I INTRODUCTION

1.1 Introduction to ECONPACK. The Army, like other institu-tions, is confronted by the basic economic problem of scarcity.Resource and budgetary limitations make it impossible to under-take all actions which are deemed desirable, thus necessitatingchoices among alternative uses of resources and funds. Aneconomic analysis (EA) helps to determine which, among variousalternatives, is the economicallv' best" course of action forachieving a given objective. ECONPACK is a software packagedeveloped to facilitate performance of EAs for Department of the iArmy military construction projects.

ECONPACK provides simple automated assistance in performing thenecessary calculations and in producing certain specified reportformats for EAs. It can also be used for the performance ofsensitivity analyses, which are especially useful in s tuationsinvolving substantial uncertainty about future costs. "

ECONPACK is available on the PAX-TYSHARE system. If a problemis incurred in running this program or in understanding what theprogram wants for input, contact Huntsville Division - ECONPACKComputer Assistance - AV 742-5266, FTS 873-5266, or CO.4 (205)895-5266, or PAX ID of BIRD.

1.2 Purpose. The immediate purpose of the ECONPACK program isto assist in the performance of economic and sensitivity analysesI. for Department of the Army military construction projects.

Advantages of using a computer program for doing EA calculationsinclude:

A. The ability to do repetitions of calculations accuratelyand with relative ease.

B. The ability to test the implications of cost projectionsby incorporating sensitivity analysis into the economicanalysis process.

C. The ability to generate standardized reporting formats "

for results.

Additionally, the ECONPACK program is structured so that:

A. Individuals having limited expertise in economic

techniques can successfully produce EAs.

B. EA output can be automatically added to a DD Form 1391prepared via the PAX System's DD Form 1391 Processor.

Use of ECONPACK in performance of EAs is beneficial for personnelat the preparation level as well as the review level for fundingrequest documentation. In this regard, the following broadpurposes of ECONPACK are particularly important:

A. To increase the effectiveness of the economic analysesprepared at installations and reduce the effortrequired by regenerations that would otherwise benecessary to bring the analyses up to OSD andCongressional standards.

B. To minimize the frustration generated at preparationlevels by reducing the number of times an analysis isreturned for regeneration.

C. To increase the effectiveness of economic analyses inminimizing the life cycle costs of constructing andoperating Army installation facilities.

D. To increase the effectiveness of documenting andcommunicating Arm., construction needs to OSD and theCongress.

EAs are intended to identi'v the least costlv alternative tofulfill a construction requirement. ECONPACK is i;itended tocontribute to the effectiveness and efficiencv with wich EAs are

conducted.

1.3 Economic Analysis

1.3.1 The Meaning of Economic Analysis. Economic scarcityrequires that choices be made in the use of resources. Ingeneral, economic analysis refers to an examination cr applica-tion of the process by which such choices are made. Economistshave developed standardized concepts, techniques, and principleswhich serve to rationalize and simplify the decision-makingprocess. An economic analysis for the Army's military construc-tion program employs the methodology of economics to svstemati-cally evaluate the economic aspects of a situation of choice andto determine the optimal course of action.

There are, of course, many contexts in which EAs are necessary orappropriate. Military construction EAs typically address thequestion of which of two or more alternatives will best accom-plish a given objective. The alternatives are mutually exclusivein the sense that which ever alternative is chosen will -adequately accomplish the objective, thereby eliminating the need

1-2

-" i-2~~* *~ - **~ S*l .- ] ~ ~ p

to also adopt any other alternative. The optimal (or economi-cally best) solution is to select the alternative which, incomparison with the other alternatives, yields one or more of thefollowing:

A. The same benefits at less cost.

B. Greater benefits at the same cost.

C. A higher ratio of benefits to cost.

The preferred alternative, in other words, will normally be theone which provides the greatest net benefits (i.e. benefits minus Lcosts).

The logic of the EA process allows for variability of bothbenefits and costs among the alternatives under consideration.In practice, however, most military construction EAs take theform of a choice among mutually exclusive alternatives whichproduce equivalent benefits or effects, but which have differentoverall cost levels. In a situation of this sort, the least .'costly alternative is the most economical. The design ofECONPACK is oriented to this approach to EAs.

1.3.2 The Economic Analysis Process. A comprehensive EA

consists of seven basic ccmponents:

A. Establishment and statement of objective.

B. Identification of alternatives. .""

C. Formulation of assumptions.

D. Determination of costs and benefits for eachalternative.

E. Comparison of alternatives.

F. Performance of sensitivity analysis.

G. Report of results and recommendations.

1.3.2.1 Establishment and Statement of Objective. The objectiveis the result to be achieved; that is, it states what the alter-natives are to accomplish. The statement of the objective shouldclearly define and quantify (to the extent possible) the functionto be accomplished. Ideally, the statement of the objective %should not presume a specific means of achievement (i.e., courseof action to bring about the desired result). If such a presump-tion is made, the statement of the objective tends to undermine

1-3

LA

........................... . . . . . . . . . . . . . . .. . . . . .. ..

=, . .. .

the analytical purpose of the EA by pre-judging the result.Compare, for example, the following statements of objectives:

A. To provide housing for 100 unaccompanied officers.

B. To construct a 100-person Unaccompanied Officers Quarters.

Statement A is preferred because it does not preclude a conclu-sion to construct a 100-person Unaccompanied Officers Quarters;it allows for the evaluation of alternative means of housingprovision.

A quantitative statement of the desired effect or objective isbeneficial because it provides an explicit test of the adequacyof possible alternative courses of action. A proposed alterna-tive may not be a viable option even if it has large net benefitsif it is judged inadequate to fully meet an actual need. Forexample, a bridge with the capacity to support 15 tons may have alarge net benefit, but is inadequate if there is a real need totransport 20-ton objects across the river.

Establishment of-and perhaps the statement of-the objective isoften a policy matter which lies beyond the scope of the indivi-dual responsible for an EA. The "analyst", however, needs torecognize the significance of this step in the EA process.

1.3.2.2 Identification of Alternatives. After the objective isestablished and properly stated, the next step is to consider allreasonable ways of satisfying that objective. Since the EAsbasic purpose is to help the decision-maker allocate resourcesefficiently, it is vital that careful attention be given toidentification of all possible alternatives which could beoptimal. The recommendation resulting from the EA will, afterall, come from among those options evaluated.

In order for a possible alternative to be considered reasonable,it should be consistent with Army regulations and legal require-ments. Adequacy and economic feasibility are other keyconsiderations in identification or definition of reasonablealternatives. Adequacy refers to the capacity of the potentialalternative to meet the actual scope or objective. For apotential alternative to be economically feasible, it must becompatible with funding realities.

1.3.2.3 Formulation of Assumptions. EAs are forward-looking inthe sense that they are focused on current decisions which leavebenefit and cost implications for future years. To the extentpossible, EAs should be based on objective "facts." The future,however, is not known completely and with certainty. Therefore,it is often necessary to make some assumptions about the future

1-4

-... .

in order to proceed witn an EA. Although some assumptions may beunavoidable, the analyst needs to keep in mind the possibilitythat the specific assumptions incorporated in the analysis mayprove to be incorrect. This possibility provides the rationalefor performance of sensitivity analysis as part of acomprehensive EA.

Examples of the kinds of assumptions which may be necessary in anEA include: the functional life of an asset, the level or extentof future requirements for a particular function, and the useful-ness of a facility after the present objective is fulfilled.Although these assumptions are made with regard to an uncertainfuture, they need not be made arbitrarilv. Fortunately, it is Loften possible to base these assumptions (or "estimates") onhistorical or technical factual information.

1.3.2.4 Determination of Cost and Benefits For Each Alternative.In practice, this step is often the most difficult and time-consuming component of an EA. The exact information needed will I.depend on the nature of the problem. The analyst must decidewhat data are needed, how relevant data are to be collected anddocumented, and when the data in-hand are sufficientlv reliableto be used in an EA.

This fourth component of the EA process is closely related to theissue of assumptions just discussed. The assumptions which mustbe made to proceed with an EA involve costs and benefits.Conceptualizing assumptions separately is useful, however,because it serves to make the analyst aware of the care whichshould be used in interpreting results. For example, although

cost figures for various expense categories are stated in dollar iterms and aggregated regardless of whether they are actuallyknown or estimated, the interpretation given to the aggregatedcosts is likely to be affected by the degree of uncertaintyinvolved.

Costs and benefits must be determined for the entire useful lifeof the project. Since timing is important in investment decisionmaking, appropriate estimates are needed for the vear in which acost is to be incurred or a benefit is to be received. Even ifactual dollar amounts are known, it should be realized thatassumptions may be necessary with respect to timing. Whileconceptual separation of assumptions from known information is -

desirable, functional overlap between assumptions and datacollection is inevitable in most cases.

The costs and benefits associated with each alternative underconsideration should be quantified whenever possible, so they mav-be systematically included in the EA calculations. Quantifica-tion, however, mav not be possible in all cases. When meaningful

" - quantification is not possible, the analyst should still attempt

1-5

. . . . . .. &

to document significant (nonquantifiable) costs and benefits sothat these may be considered when arriving at alternative coursesof action.

1.3.2.5 Comparison of Alternatives. Since the aim of an EA isnormaily to choose among alternative courses of action, compari-son of the costs and benefits is the central focus of the EAprocess. To the extent that the relevant costs and benefits canbe accurately measured or reliably estimated, the comparison ofalternatives can be greatly facilitated by computer assistance.At this stage on an EA, the quantifiable benefits of the alterna-tives are equivalent, thus, further facilitating comparison. Insuch cases, the EA computations lead to aggregated cost measureswhich are readily comparable; other things being equal, the leastcost alternative is optimal.

In comparing alternatives, it is important to considernonquantifiable benefits and costs as well as the quantifiableones which enter into the calculations. This is especially truein situations in which the quantitative results of two or morealternatives are equal (or almost equal). That is, the smallerthe quantitative variation among alternatives, the greater theimportance of other considerations.

The process of comparing alternatives also presents anopportunity to reevaluate the reliability of the cost and benefitestimates incorporated in the analysis. This is particularly "%advisable when both aggregated costs and aggregated benefits oftwo or more alternatives are approximately the same.

1.3.2.6 Performance ot Sensitivity Analysis. When the resultsof the above step do not reveal a clearly superior alternative,it is useful to include one or more sensitivity analyses as partof the EA. A sensitivity analysis allows the analyst to engagein a "what if" process to determine how critical the particularassumptions used in the EA are to the EA results. In the sensi-tivity analysis, selected parameters or assumptions are allowedto vary by a specified percentage to determine whether or not anerror in estimation of costs is likely to lead to an inappro-priate ranking of alternatives.

Since the purpose of the sensitivity analysis is to test howsensitive the results are to variation in costs, it is especially ourimportant tc subject expense items, which are relatively large ""and uncertain to sensitivity analysis. If small variations inexpense items cause a change in alternative ranking, the analystmay be well-advised to reevaluate estimates and refine them in e:order to reduce the degree of uncertainty.

W- I ! ++ l!

By including the results of the sensitivity analysis in the finalEA presentation, the analyst assures the decision-maker andreviewer that uncertainties have been considered.

1.3.2.7 Report of Results and Recommendations. The EA reportshould be comprehensive and should include data sources. To theextent possible, it should serve as a "stand-alone" document forthe decision-maker to use in deciding on appropriate use ofresources. From the perspective of the analyst, the ranking ofalternatives by comparison of costs and benefits (step five ofthe EA process) and the sensitivity analyses (step six) arelikely to appear straightforward and self-explanatory. Thedecision-maker, however, needs additional information. -

The structure of the report should begin with a summary of theanalysis, including recommendations based on the content of theEA. The actual decision may be based on non-economic as well aseconomic considerations. The EA recommendations should notautomatically be interpreted as the "right answer" for decision-making purposes, but rather as an important input into the finaldecision-making process. The analyst should therefore limitrecommendations, based on ECONPACK, to the economic aspects ofthe problem.

Following the summary and recommendations, the EA report shouldprovide a step-by-step explanation of the basis for therecommendations. This explanation should ideally follow thestructure of the EA process itself. That is, it should include:statement of objective (requirement to be met); definition ofalternatives; explanation of assumptions; cost and benefit dataand sources; comparative ranking of alternatives based on costsand benefits; and sensitivity analysis result.

1.3.3 Summary of Governing Regulations. The Department of Armyhas two regulations governing the use of economic analysis. AR11-28, Economic Analysis and Program-Evaluation for ResourceManagement, provides guidelines for conducting an economicanalysis of Army projects. AR 414-15, Military Construction,Army Program Development, applies these general rules to militaryconstruction projects. Both regulations are summarized below.To obtain a copy of regulation AR 11-28, contact HQDA (DACA-CAF),Washington, DC, 20310. To obtain a copy of AR 415-15, contact:HQDA (DAEN-ZCP-M). Washington, DC, 20314.

Summarv of AR 11-28

Purpose: Economic considerations are essential in determininghow to allocate limited resources. An economic analysis is amethod for assuring that mission managers establish the

"" objectives of a proposed project, research alternative means

for meeting the objectives, and determine the cost andbenefits of each alternative. An economic analysis summaryshould "answer concisely the fundamental question the missionmanager is faced with--will the results (benefits) be worththe costs if the action is approved?."

ECONPACK does not constitute a complete economic analysis becauseit does not attempt to account for the benefits of a project.ECONPACK does, however, provide information which is essential tothe overall cost/benefit analysis.

Applicability: All proposed construction projects submitted toheadquarters for approval must be accompanied by an economicanalysis or a statement justifying why an economic analysis wasnot performed. In general, an economic analysis is requiredwhenever a project requires funding for the first time or wouldrequire an adjustment to a previously established budget. Aneconomic analysis is not required if the following apply:

1. "The benefits of the analysis are not worth the minimum levelof effort to do the analysis.. .The degree and depth of theanalysis, should be commensurate with the complexity o.1 theaction proposed... In some cases, the analysis may involve only anhour s research, but it provides the basis for a more informedand considered decision." O L2. "DoD instruction/directives prescribe equipment age orcondition replacement criteria, labor and equipment trade-offstandards, or requirements computations."

3. "The proposed actions are mandated by statute, regulation ora directive of higher authority which preclude any choice ortrade-off among alternatives..'.This exception does not apply ifthe proposal is the result of a congressionally approved Armyrequest, rather than an action initiated by Congress."

Responsibility: The economic analysis should be performed at thesame organizational level that originated the request forresources. The responsibility for assuring that the analysis isperformed rests with the mission manager. Each command levelmust also evaluate the completeness and accuracy of the economicanalyses it submits.

Ingredients of an Analysis: Each analysis must contain theseminimum elements:

--The objective of the proposed action.

--Specification of assumptions and constraintsunderlying the analysis. "

--Identification of alternatives.

SUMMARY OF 415-15

S" Purpose: This regulation applies the general principles set outin AR 11-28 (see pages 1-7 through 1-9) to military constructionprograms.

Applicability: This regulation applies to the Active Army. The LZArmy National Guard and the US Army Reserve are also covered whenthey are tenants on Active Army installations.

Requirements: AR 415-15 requires a detailed project-" justification for most military construction proposals. This

detailed justification is contained in Block 11 of DD Form 1391,which consists of 18 justification paragraphs. This summary willexplain two paragraphs dealing with economic analysis, and athird section concerning special requirements paragraphs.

AR 415-15, 8-5, Consideration of Alternatives: This sectioncovers paragraph four of the justification form, which requiresanalysts to evaluate all alternatives to a proposed project.Examples of possible alternatives include similar on-postfacilities, available off-post facilities, and nearby militaryfacilities. A summary of the analysis of the alternatives mustbe given. Key economic data should be included under paragraph11 of the justification.

AR 415-15, 8-12, Economic Justification: All militaryconstruction projects justified on an economic basis must includean economic analysis, which is to be summarized in paragraph 11of the justification. The summary should include all keyeconomic data and an explanation of the economic analysis, SRP-1.SRP-1 will include the actual economic analysis. If an analysiswere not performej, the justification for waiving it should bestated here.

AR 415-15, 9-2, Special Requirements Paragraphs (SRP): TheSpecial requirements paragraphs of DD Form 1391 provide for the rinclusion of extended analytical and statistical material andother special documents.

~'~%1.3.4 Types of Economic Analysis. Army guidance categorizes EAsinto two separate types: primary economic analysis and secondaryeconomic analysis. The structure of the economic analysisprocess is similar whether the EA being produced is primary orsecondary. However, budgetary effects, report formats, andcertain computations, differ somewhat depending on analysis type.

1.3.4.1 Primary Economic Analysis. A primary EA is designed todetermine whether an existing situation or procedure should bechanged in some way to take advantage of dollar savings availablethrough some other situation or procedure. In a primary EA,then, direct comparison is made between new alternatives (newways of meeting an existing requirement) and the status quoalternative (the way the requirements is currently being met).If two or more new alternatives are being considered, each iscompared directly to the status quo alternative.

In this framework, the objective or requirement is already beingmet. The question is whether it could be met more efficiently(i.e., at less cost) in a different manner. The focus, then, ison the net savings which may be possible by substituting a newapproach to meeting the requirement in place of the status quoapproach.

As an example of a situation in which a primary EA would beappropriate, consider an installation which currently purchasescertain maintenance services from a local company. Continuationof this practice would represent the status quo alternative. Ifthe same maintenance services could be obtained by employment ofadditional personnel at the installation, this would represent anew alternative. A primary EA would not be concerned withjustification of the need for the maintenance services, but itwould address the question of whether or not the services couldbe obtained at less cost (i.e., with a positive net savings) ifthe new alternative (additional personnel) were instituted inplace of the status quo alternative (purchase from a localcompany). If the new alternative turns out to be less costly andis adopted, the effect is to reduce budgetary outlays.

1.3.4.2 Secondary Economic Analysis. A secondary economicanalysis is designed to determine which of two or more ,.

alternative courses of action would most economically fulfill an -a

objective or requirement which is not currently being met. Sincethe objective is not already being satisfied, in this case, thereis no status quo alternative; all alternatives begin on an equal %- .,

footing and each must be compared against each of the others. In .5'

the absence of a status quo alternative as a fixed standard ofreference, the focus of this type of analysis is on net lenefits I I(benefits minus costs) rather than on net savings. In the commonuse of equivalent benefits for each of the alternatives under

1-10

>I.......... 0 .5.--- - -- ,

. . . . . . . . . . S S

'.4

use of equivalent benefits for each of the alternatives under

consideration (i.e. benefits or effects sufficient to meet theneed specified in the objective), the problem becomes one of costminimization. Overall costs are calculated for each of thealternatives and then ranked; other things being equal, theleast-cost alternative is preferred.

While this analysis type does not directly calculate net savingsfrom a status quo situation, the savings resulting from onealternative (e.g., "3") can easily be calculated as the overallcost difference between the two alternatives (e.g., overall costof alternative A minus overall cost of alternative B). Thus, thesecondary analysis framework also allows the issue of savings tobe addressed, though in a less direct fashion. Interpretation ofthese savings, however, requires further consideration. In thecontext of meeting a new requirement, an increase in budgetaryoutlay will be required; the saving represents a relative ratherthan an absolute saving. That is, while budgetary outlay willincrease (thus no absolute saving), the increase in outlay withthe most economical alternative will be smaller than would occurif a different alternative were to be chosen (thus a relativesaving).

It should also be noted that in situations where a primaryanalysis can be conducted (i.e., where a status quo alternativedoes exist), the analyst may choose to conduct a secondary

analysis. In this case, the status quo alternative is simplyspecified as one of the several alternatives to be consideredequally with the other alternatives. This allows for directcomparison of all alternatives (including the status quo) andranking by overall cost levels.

1.3.5 Report Formats. ECONPACK report options include requiredformats for automated inclusion in the DD Form 1391 as preparedvia the DD1391 Processor. These standardized report formatssummarize the essential data included in an EA, and thereforeconstitute a substantial component of a comprehensive EAsubmission. In running the ECONPACK program, user specificationof analysis type (primary or secondary) automatically dictateswhich of the two required formats (A-i or A) will be included;therefore no separate format specification is required. Anoptional format (B) can be used along with the required formatsfor both primary and secondary analyses. Formats A-i, A, and Bare shown in Appendix C.

1.3.5.1 Format A-i. Format A-i is required for a primaryanalysis. This format summarizes the calculation steps used todetermine the net present value of the cost for the proposedchange (i.e., new alternative) and the net present value of thesavings estimated to result from the proposed change.

.1-11

.. . ,

Format A-i also includes the savings to investment ratio (SIR)and the discounted paybacks period (DPP) for the new alternative.

-: Both of these measures are indicators of the attractiveness ofimplementing the proposed new alternative in place of the statusquo alternative. The SIR is net savings divided by net invest-ment (both in terms of present value). The DPP is the number ofyears from the time the project (alternative) is initiated to the Ltime when the present value of investment costs is equal to thepresent value of savings. The larger the SIR (i.e., the greatersavings are relative to the investment required to achieve them)and the smaller the DPP (i.e., the shorter the period requiredfor savings to offset the investment costs which generate them),the more attractive is the alternative.

1.3.5.2 Format A. Format A is required for secondary analysis.This format summarizes the calculation steps leading to the netpresent value of the project costs for a given alternative.There is one Format A for every alternative included in asecondary analysis. Using Format A, the analyst and thedecision-maker can directly compare the costs (in present valueterms) of all alternatives under consideration.

1.3.5.3 Format B. Format B, "Summary of Project Benefits," isoptional. it provides an !xplanation of any benefits which mayresult from an alternative under consideration.

In the case of primary analysis, the savings resulting from aproposed change can be thought of as benefits. For secondaryanalysis, most EAs involve determining which alternativerequires the least cost to reach a given objective cr benefitlevel. Format B can be used for a discussion ef projecteffectiveness. Some project alternatives may have significantnonquantitative advantages or shortcomings which can be indicatedby use of Format B.

1.3.6 Non-Housing vs. Housing Analysis

1.3.6.1 Non-Housing Analysis. In a non-housing analysis, thefollowing assumptions are made automatically:

A. A ten percent (10%) discount rate.

B. Continuous discounting.

C. No inflation.

*D. No residual schedules.

1.3.6.2 Housing Analysis. Greater user flexibility is allowed

in the performance of EAs using ECONPACK if a housing analysis isspecified.

ECONPACK is structured to allow a discount rate of other than 10percent to be used. Given a fixed expense stream for futureyears, use of a higher discount rate will result in a lowerpresent value of costs whereas, use of a lower discount rate willresult in a higher present value of costs. It should be noted,however, that current DoD policy for EAs requires that a 10percent discount rate be used.

Continuous discounting assumes that costs for a given year arespread evenly throughout the course of the year. In some cases,however, the costs may occur at a particular point in time (e.g.,at the end of the year). In this situation, use of the end-of-year discounting convention will provide a truer measure of thepresent value of the costs. In a housing analysis, the user canspecify use of a discounting convention other than that ofcontinuous discounting.

In general, DoD policy requires that EAs be done in constant(i.e., uninflated) dollars. Although the general inflation rateis not applied to constant dollar cost estimates for futureyears, ECONPACK allows for the use of differential inflation inthe performance of EAs. Differential inflation is the differencebetween the rate of inflation for a particular expense item and -

the general inflation rate for the economy as a whole.

Specification of an EA as a housing analysis enables the user tomake use of residual schedules, an option not available in a non-housing analysis. Residual schedules make it possible to deter-mine residual (or salvage) values for assets at any point duringthe period of analysis. The analyst is thus given increasedflexibility in treatment of asset valuation.

If the extra features available in a housing analysis areneeded in an EA which is not actually concerned with a housingproblem, the analysis should be classified as "housing" in theoperation of ECONPACK.

1.4 ECONPACK User Modes. The User can prepare an ECONPACK inputfile in either of two ways. The input file can be entered bymeans of a terminal prompting mode or by means of a file inputmode utilizing the computer system editor program.

1.4.1 Terminal Prompting Mode. Use of this mode requires littleknowledge of the computer system and relatively limited expertisein economic analysis. It is, therefore, especially appropriate

. . . ...

beginning to produce EAs using ECONPACK to become familiar withthe terminal prompting mode even if the user expects ultimately rto use the file input mode.

The terminal prompting mode is interactive. Entering data orcreating an input file is accomplished by responding to a seriesof prompts. This prompting sequence leads the user step-by-stepuntil the input file is created and the program is ready forexecution.

Chapter 5 of this manual discusses the terminal promptingmode.

I1.4.2 File Input Mode. The file input mode is a less rigidlystructured means of creating and editing input files on ECONPACK.This less rigid structure has a significant advantage in that itallows greater user flexibility than is possible with theterminal prompting mode. Also, it allows for certain options notavailable with terminal prompting. On the other hand, the fileinput mode has the disadvantage of requiring substantiallygreater knowledge of the computer system and of the economicanalysis process since the user is not explicitly directedthrough the input procedur.-

CHAPTER 2SELECTED ECONOMIC CONCEPTS USED IN ECONOMIC ANALYSIS"L

2 ECONOMIC CONCEPTS IN ECONOMIC ANALYSIS

2.1 Introduction. The purpose of this chapter is to provide

background information about a few economic concepts which needto be understood by creators of military construction EAs.Further, the terminology introduced should be helpful to noviceusers of the ECONPACK software package. This chapter is notdesigned to define "all" of the concepts employed in EAs.Appendix A of this manual is a glossary which can be referred tofor definition of concepts unfamiliar to the user. b.

2.2 Discounting. Most military construction EAs are essentiallycost minimization problems - i.e., analysis of how a given objec-

tive can be fulfilled at least cost. The dollar costs are not,however, completely comparable because they occur at differentpoints in time. The discounting process serves to adjust dollaramounts so that costs incurred at different points in time can bedirectly and meaningfully compared. This adjustment reflects thefact that the significance attached to a particular dollar amountto be paid (or received) at a later date is less than thesignificance attached to the same dollar amount to be paid (orreceived) now.

The discounting process can most easily be understood by firstexamining its opposite, the compounding process. Assume that arenewable loan of $1,000 is made at an annual interest rate of10 percent. The $1,000 used to make the loan is money held now;

therefore it represents a present value (PV). If the loan isrepaid after one year, the repayment amount is $1,100, of which$1,000 is principal and $100 is interest. This $1,100 to bereceived one year from now represents a future value (FV).Letting the subscript indicate the number of years until repay-ment, and "i" represent the interest note, this relationship canbe expressed as:

FV=PV(1+i).

Substituting our assumed values for P\V and i yields:

FV=$1,000(1+0.1)= $1,000 (1.1)= $1, 100.

If, instead of receiving repayment at the end of one year,the loan is renewed for a second year, its future value at theend of two years is $1,210. The interest received for the secondyear of the loan is $110, or $10 more than the interest accruedduring the first year. This represents interest accrued on otWh

"'-the $1,000 principal amount and on the $10() interest at(rued"

2-1.

77b -7Z

in the first year. The calculation is as follows: C;,FV 2=F (1+i) = $1,100 (1+0.1)= $1,210.

Since FV is PV (1+i), substitution reveals that:

V pV (l+i)(1+i) =$1,000(1+0.1)2 = $1,000 x (1.1)2=

$1,000 x 1.21 -$1,210.

Extending and generalizing this pattern leads to the followingexpression as the formula for calculation of future value for nyears:

FVn PV (l+i) n .

Discounting, is the opposite of compounding. Whereas compoundingis the process of converting present to future values,discounting is the process of converting future values to presentvalues. The present value of a given future amount to bereceived at a specific future date (i.e., after a specific periodof time) is equal to the present amount that would accumulate tothat future amount by that date given a particular interest rate.For example, the present value of $1,210 to be received two yearsfrom now is $1,000 if the appropriate interest note is 10percent. The fornula for calculation of present value (for theend-Of-ye3r ccnv.3ntjon) c.in easily be derived from the formulafor fttuie ,,ilve caicul.t.on. Since j

FVn =PV (1+i)

it follows that

PV=(FVn)(l/(I+i)n)

The interest rate (i) in this formulation is known as thediscount rate. Current DoD policy requires a 10 percent discount -.

rate for EAs. ".-

.-I'2.3 Inflation and Differential Inflation. The term "inflation"refers to a general rise in price levels in an economy. If theexpected inflation rate is judged to affect all costs of an EAequally, no special treatment is necessary. However, if certaintypes of costs are expected to suffer from a higher level ofinflation than the general economy, ECONPACK has the capabilityto handle this situation with the differential inflation feature.Specifically, the user can apply a differEntial inflation factorto any expense item in the EA. Since the concept is "differen-tial" inflation, the user would use a factor representing thedifference between the expected general level of inflation and theexpected level of inflation for a particular expense item.

J. %,

For example, if the expected general level of inflation is 10percent and the expected level of inflation for a particularexpense item is 15 percent, the differential inflation factorwould be 5 percent.

2.4 Determination of Asset Value Over Time. Most assets do notretain their full value over time. In private sector applica-tion, this phenomenon is dealt with through the depreciationprocess. Depreciation, as used in the private sector, isoriented primarily toward tax effects rather than toward actualerosion of asset value over time. Since the government pays notaxes, depreciation per se is irrelevant and should not be in-cluded in EAs of government investments. Realistic valuation of_.-government assets, however, does require that account be taken ofthis reduction in asset value. ECONPACK allows for such asset .

value adjustment in two ways: utilizing a residual schedule orstating a salvage value.

2.4.1 Residual Schedule Method. At this point, it is useful to

define four key concepts:

I) Residual Start Value: The asset's original value.

2) Residual Factor: The proportion of the original assetvalue retained in a given year.

3) Residual Value: The dollar amount of asset valueretained in a given year (i.e., the residual start valuemultiplied by the residual factor for a given year).

4) Residual Schedule: A list of residual factors.

The user may choose from among three "sub-options" if electing to.. employ the residual schedule concept instead of the salvage value

concept: the straight line depreciation schedule (SL), theamortization declining balance schedule (DB), or a user specifiedschedule (US). The last schedule would be prepared based on theuser's judgment of asset value erosion for the particular type ofasset.

2.4.2 Salvage Value. A second way to recognize depreciation isby stating a user specified salvage value (also referred to as"terminal value"). Normally, a salvage value is a nominal sum 2.at which an asset is valued at the end of its functional life. -.

TECHNICAL INFORMATION

3 TECHNICAL INFORMATION

3.1 Introduction. The purpose of this chapter is to explainsome of the capabilities of ECONPACK, provide more detailedinterpretations of selected EA terms, and explain key proceduresfor using ECONPACK.

3.2 File Space. Each user is allotted a fixed amount ofdisk storage space. The report file from several analyseswill consume much of this space. Also, a certain amountof disk space is temporarily required during programexecution. One analysis may require 600 blocks of freedisk space. The user may ascertain available disk spacein two ways:

1. This information will be made available almostimmediately after choosing the ECONPACK option from .-the PAX Menu.

2. Enter the CMS mode by choosing Option 7 from theECONPACK MAIN MENU. At the C>, type QUERY DISK A (CR).This will display the percentage of disk space availablefor the label under which the user logged in.

To leave CMS and return to ECONPACK, type ECONPACK (CR) atthe C>. To return to the PAX Menu, type LOG (CR) at the C>.

If additional disk space is needed, call Jean Sherwood at AV 285-0578,FTS 272-0578, or COMM (202) 272-0578 and request additional cylindersbe added.

3.3 Negative Inputs. The user may be required to use negative inputson at least two occasions:

1. Normally an expense item is a cost. However, if the userdesires to show an influx of funds for a particular alternative, theminus (-) sign may be used to indicate an expense item as a negativeinput. Negative expense items should be avoided in performing asensitivity analysis.

2. The terminal prompting routine will ask if each

alternative has a salvage value (also known as a .'terminal value). Usually a salvage value is a positivenumber, indicating a nominal value at which an asset isvalued. However, if an expenditure of funds would be

3-1

'>. . - . . - . . - .. . . ... .. .. . . . .-. ..3

°-s.- .-. .-.. .-.-.- " b . . -- - .

required to remove an alternative, the user may reflect , "this fact by stating the salvage value in negative -

terms. (For example, demolition costs are expressed asnegative numbers.)

3.4 Entering Maintenance and Repair Costs. Normally, certainccsts must be incurred on a periodic basis to keep a facilityusable (maintenance costs) or to refurbish a facility (repaircosts). It is important to correctly state the timing of thecosts for a consistent and correct EA.

To illustrate, assume an alternative calls for constructing afacility with a 25 year economic life. Further, assume that itwill take 3 years to construct the building. rhus, the period ofanalysis is 28 years.

Assuming maintenance costs of $50,000 a year are expected, thecorrect data entry would be three years of no cost followed bv 25years of $50,000/year, expressed as 3*0 25*50000, since nomaintenance costs would be incurred during the three-yearconstruction phase.

Assuming the analyst predicts that a neu roof costing $50,000 willbe needed1 in vear :0, the correct data entrv for the repair costwouid be 12*0 5030() 15*0 siowing no costs during the first 12vears of the perioa of anaivsis, a $50,OCO cost in the 13th year,and 15 more years of zero repair costs.

3.5 Warnings. If using the terminal prompting mode, do not usesingle quotes in any input as it will cause major errors in theanalysis routine.

All cost data should be entered in actual dollars and not in thou-sands or millions of dollars. Do not use commas or dollar signs.Use whole numbers.

If the user supplies an input filename which is the same as an -

input filename which already exists, then the input file createdwill erase the existing file and replace it with the new file.

3.6 Limits on Files Created. The following limits apply tofiles created with the terminal prompting mode:

3.7 Procedures For Using ECONPACK. The procedures presented in

this section provide instructions for using ECONPACK. Thespecific procedures explained are:

1. Logging on to the Economic Analysis Computer Program

(ECONPACK)

2. Selecting the IBM or QED Edit Choice/Mode k3. Verifying An Edit Choice

4. Changing An Edit Choice

5. Logging off ECONPACK and the PAX System

NOTES:

1. In all procedure sections, data to be entered by theuser is underlined. Parentheses () indicate keys on thekeyboard to be used during the computer/userinteraction. (Ex. - (CR) means the user should type thecarriage return key once.) Additional notes areenclosed in brackets.

2. Once the user has initiated the prompting routine tocreate an input file, the command /QUIT may be enteredat any prompt to terminate the routine. The system willprompt the user to indicate whether or not the partiallyconstructed input file is to be saved on the user'sSystem Disk.

3. ESCAPE KEY. Once execution of the analysis programbegins, the user should not stop the execution unlesssomething is obviously wrong.

If a need to stop the analysis arises, depress theESCAPE key once. The system should respond with a ??>prompt. At the ??> prompt, enter HX and depress (CR).This halts execution. The user will then receive Fanother prompt at which an option from the MAIN ECONPACKMENU should be entered.

4. /HELP. The user can enter /HELP at any prompt, in the% terminal prompting mode, for a message from ECONPACK as

to the appropriate response for a prompt. -

5. ASSISTANCE IN LOGGING ON, COMMUNICATIONS, or EQUIPMENT ,vINTERFACE. TYMSHARE'S 24-hour HOTLINE (COMM-703-893-4243) or FTS (202-893-4243) is available whenever a userneeds assistance with logging on, communications, or

equipment interface.

3.7.1 Logging on to the Economic Analvsis Computer Program

(ECONPACK)

STEP 1: ESTABLISH TELEPHONE COMMUNICATION WITH THE COMPUTER.

The user must first establish telephone communicationwith the computer. This step is accomplished in variousways dependent upon the type of equipment being used aswell as how that equipment has been set up. Some users

may simply have to turn the equipment on, hit aspecified key on the keyboard, and the communicationsline will automatically be accessed. Others may have todial the assigned telephone number, listen for a high-pitched sound, and then insert the telephone receiver inthe terminal's coupler or release a specified button onthe equipment's m)dem. Once the appropriate steps havebeen followed to e3stablish telephone communication withthe computer, the svstem will quickly prompt the user toenter a "terminal identifier". To prompt the user, thesvstem will either display a string of garbage-like ucharacters or actually print the words "PLEASE TYPE YOURTERMINAL IDENTIFIER". The user should respond byentering the terminal identifier. A terminal identifierindicates to the computer the type of equipment requiredto communicate with the user's terminal. If the wrongidentifier is entered, telephone communication willprobably be terminated. [See Appendix B for a list ofappropriate terminal identifiers for various equipment. I

EXAMPLE:

Establish communications line. L.PLEASE TYPE YOUR TERMINAL IDENTIFIER A

STEP 2: "LOG ON" TO THE COMPUTER AND THE PAX SYSTEM.

Once the terminal identifier has been entered, thesystem will prompt for the System User ID and SystemPassword assigned the user's activity. These two wordsidentify the user, the programs that user may access,and the activity to be billed for the session. (If the

correct System ID and Password are not entered within 2 . '

communication, the computer will automaticallydisconnect.] The system then prompts for a "projectcode." The user should enter his/her initials. The

system then responds by printing the date and time theuser logged on to the computer.

. *

Once logged on to the computer, the user has immediateaccess to the PAX System. The system indicates thePAXMAIL status for the user's System ID. [PA- MAIL is afeature of the PAX System which allows PAX users tocommunicate with each other.] The system then respondswith "LOG ON" messages which provide a variety of urgentinformation. Following the LOG ON message is a displayof the PAX SYSTEM MENU, in which the system lists thecomponents of the PAX System available to the user. Thenumber of components available to each System ID willvary. The system then prompts the user to make aselection.

The following presents a discussion of each menu option.

4.2 MAIN ECONPACK MENU Option 1: Create an Input File. This

option allows the user to input the data file for an EA. Thecomputer program, by a prompting routine, will ask for all theneeded data. Chapter 5 discusses this aspect of ECONPACK in moredetail.

The prompter uses the data input option to form "blocks" ofinformation which are used by the main program to perform the EA.These "blocks" and their explanations are listed in the following:

CHAPTER 5TERMINAL PROMPTING MODE

5 TERMINAL PROMPTING MODE

5.1 Introduction. This chapter is for analysts who wish to usethe prompting mode rather than the file input mode. The terminalprompting mode is especially appropriate for the person who doesnot use ECONPACK frequently. Knowledge of creating a file usingthe Conversational Monitoring System (CMS) is unnecessary.

5.2 General. A sample interactive session in which a file iscreated is given in this chapter. The analyst must organize theinput data so that it is readily available when the programrequests it. The following outline for data/notes is recommended:

Report titleOrganization titleProject titleObjective of analysisPeriod of analysisStart yearBase yearInflation index schedile (if applicable)Residual schedule (if applicable)Type project (non-housing or housing)Type analysis (secondary or primary)For each alternative:

List of expense items and amountsSalvage value (if applicable)Source of dataQuantifiable benefits and sourceNon-quantifiable benefits and source

Titles of sensitivity analysesList of which expense items to change and limits on changes . -

in sensitivity analyses.

5.2.1 Non-housing vs. Housing. The program gives prompts forthe information needed to perform the EA. There are two keychoices early in the prompting sequence which determine what kindof analysis is to be performed. One is:

DO YOU WISH TO DO A HOUSING ANALYSIS?

A "yes" answer allows the analyst several features which arenot normally used in a non-housing analysis. These are: ..".

5-1

I..

% '

The option to include an inflation schedule. If anexpense item(s) is expected to increase in price at a ratehigher than the rate for the general economy, one may setup a schedule of the differential rate.

* The option to include a residual (salvage) valuedepreciation schedule. With this option, the program will

calculate the residual value which would apply at any pointduring the period of analysis. It calculates thisresidual based on a user-selected preset type of deprecia-tion, as well as a start value and time frame, also set bythe user.

The option to use other than mid-year discounting. KIf a non-housing EA requires the above, the analysis should bedone using the housing option.

A "no" answer results in a standard EA run, using a 10 percent(10%) discount rate, mid-year discounting , no inflation, and noresidual schedules.

5.2.2 Secondary vs. Prinary. Another key question is:

ENTER THE ANAL'SIS TYPE PRIMARY OR SECONDARYIL-L-

This determines the type of special format reports that will begenerated. For a primary, the Format A-i report will be pro-duced, while a Format A report will be produced for a secondaryanalysis.

5.3 Sample Input Session. The following example demonstrates useof ECONPACK to interactively input a file for an EA:

The analyst lists the following information for easy referencewhen using ECONPACK:

Requirement - to house an additional 100 officers at Ft.Anywhere. There are three alternatives: construct new quartersrenovate existing buildings, or have them live on the economy innearby towns.

A sample interactive input session is presented in this section.The following paragraphs discuss the printout in detail.

5.3.1 Initial Information. The report title, organization, dateof analysis, project title, objective and action officer are allgiven here. [Normally, also enter the telephone number of theaction officer.]

In this example, the analyst prints out the initial informationblock for review. Information can be changed by entering "C".

5.3.2 Data Information. The total period of analysis is 17years--occiparicy is in 1992 and construction begins in 1990 foralternative 1.

The start year is the first year of the period of analysis forwhich cost data are included. The base year is the year to whichall costs will be converted to present value amounts.

One differential inflation index will be used for allowances. Itis 2.2 percent per year and starts in 1991.

Two residual schedules are used--one for depreciating the newconstruction and one for the renovation.

5.3.3 Alternative Data. Note that the lives of the alternativesare 15 years beginning in 1992. For the residual calculations,end-of-year discounting is normally selected.

5.3.4 Graph Information. All three alternatives are selectedfor graphing.

~'-'. 5.3.5 Sensitivity Analysis. The analyst varies the O&M costsfor renovation as much as 50 percent to see if this affects the rranking of the alternatives.

5.3.6 Other Prompting Sequences. The sequence given aboveexemplified a secondary housing analysis. The sequence is similarfor a secondary housing analysis and for non-housing primaryand secondary analyses.

The differences between the kinds of analyses are that someadditional input data is requested for a primary housing analysisand less data for non-housing analyses.

5.4 Execution. Once all the information is entered, the analysthas the choice of executing ECONPACK with the new input file. Ifthe response is "N" then the input file is saved and the analystis returned to the MAIN ECONPACK MENU. .,,-

The standard report for this example is given in Appendix D.

5.6 Terminal Prompting Format. The sample terminal promptingsession uses the following format: k

CHAPTER 7FILE INPUT MODE

7 FILE INPUT MODE --

7.1 Introduction. This chapter is for analysts who chooseto create their input file(s) using the CMS editor on theTYMSHARE system. This chapter presents the details of re-quired input for doing an ECONPACK EA run. It is important

*' that the analyst become well acquainted with the generallayout of an input "file". A word of caution: filescreated in this manner are not necessarily usable with theterminal prompting mode, described in Chapter 5.

The ECONPACK computer program is a very flexible piece ofsoftware, containing many optional features for doing EAs. Theterminal prompting mode discussed in Chapter 5, while requiringlittle knowledge of the computer system, offers little freedom inutilizing these options. In the file input mode discussed inthis chapter, the user/analyst has freedom to use any of theavailable options, along with the responsibility to devote morethought to the process.

This chapter is designed to "stand alone". Due tonecessity, economic concepts and computer commands areinterspersed. For the user's convenience, a command summaryis presented on the left side of the page. These summariesprovide a quick reference for the commands explained indetail on that particular page.

7.1.1 Sample Input File. The input file consists of severalmajor sections, or "blocks", summarized below:

A description of these major blocks is presented on thefollowing pages.

NOTE: Input data lines are limited to 72 characters (includingquotes and ampersands). Ampersands may be used to indicatecontinuation of data on the following line. NO BLANK LINES ARE

3. Data (Continued) Specification of a base year whichis later than the start year willcause the net present value figuresfor alternatives to be larger; butdetermination of the least costlyalternative is unaffected by thischoice.

In an EA, it is the relativedifferences between alternatives,and the order of preference that is -'-

important, not the actual amounts L'involved. The key to correctlycomparing these numbers is that thesame point in time be used.ECONPACK guarantees this byautomatically applying the samestarting point and the same periodof analysis to all alternatives.

By allowing the user to specify aBASE-YEAR in addition to a START-YEAR, a convention preferred bysome analysts is made possible.This convention is to convert allthe costs of an alternative to apresent value amount as of thebeginning of the economic life ofthe facility.

Consider, for example, the case ofthree alternatives designed tosatisfy an objective from FY 1995through 2004. If one of thealternatives requires a 3-yearconstruction period and the othersrequire only 1 year each, then theperiod of analysis should be from1992 through 2004. This allows thecosts for the alternative requiring3 years of "lead" time forconstruction to be included (for1992, 1993, and 1994).

The program convertsthis amount to a present worth andsubtracts the resulting value fromthe present value of the expenseitems to arrive at a net presentvalue of the cost of thealternative.

H. SALVAGE VALUE The SALVAGE VALUE statement[Optional; if used, consists of the required identifierfollow with the phrase SALVAGE VALUE followed byamount of the the amount of the salvage value.salvage value.] This amount should be in

If aresidual or return of some kind isknown to be part of a alternativeat some point during the period ofanalysis other than at the end ofthe last year (e.g., if thealternative involves the sale ofsome equipment or its release forsome other productive governmentuse), then this effect can beincluded simply as a cost item witha negative sign.

By making use of the RESIDUAL VALUEfeature, the salvage valuecalculations can be included usinga preset residual factor schedule.

4. Alternatives This feature calculates what the(Continued) salvage (residual) value would be

in each year if the project were tobe terminated in that year, andsubtracts this amount, in presentvalue terms, from the cumulativepresent value of the expensesincurred for the alternativethrough that year. As a result,the analyst is able to see thecomparison of alternatives forassumed project termination notonly at the end of the period ofanalysis, but at the end of everyyear in the period of analysis aswell.

There are three "sub-options" for _)calculating depreciation: the . -

straight-line method, the

amortization declining balancemethod, or the user's own method.The user may specify an inflationindex to apply to the residualfactor, if applicable. A discountfactor may also be specified.

When doing an EA run which includessalvage or residual values, allalternatives must use the sameconcept. Either all alternativeshaving such an occurrence shoulduse the residual value feature, orthey should all use the salvagevalue statement approach. Theprogram will run with a mixture ofthese two concepts, but the resultswill be somewhat misleadin6. Theend results to the last year of theperiod of analysis will beappropriately comparable.

ful, since the residual featuremethod shows net cumulative present

4. Alternatives A review of the summary shows that(Continued) for a secondary analysis, if a

special format report is to begenerated, then every expense itemin the alternative must be identi-fied as either an R&D, an invest-ment, or a recurring annualexpense. A similar requirementexists for each of the other twocategories of alternatives.

Explanations for these formatreport statements are providedlater. For either of the formatreports, the computer program addstogether, for each year in theperiod of analysis, all if theexpense items for each category asidentified by these report formatstatements.

In the case of secondary analysis,sums for the three categories areprinted out in the Format A report,left to right. Then the sum andthe discounted sum are printed outfor each year in the period ofanalysis. These discounted annualamounts are then summed to show thecumulative present value of allcosts, excluding any salvage/residual value which may beinvolved for the entire period ofanalysis. The uniform annualequivalent of this amount is thenshown, followed by the samefigures adjusted by subtracting theapplicable salvage/residual value.

In the case of primary analysis, asimilar process takes place.Primary analysis looks at the EA ina slightly different way, asreflected by the A-i format.

4. Alternatives The issue addressed in a primary EA(Continued) is whether a proposed alternative

to the status quo will result insavings sufficient to offset anycosts required to implement such a

change.

The A-i format shows thesubtraction of the sum of therecurring costs for the proposedalternative from the recurringcosts for the existing situation.This difference is shown for eachyear, is discounted, and thesediscounted annual amounts aresummed to arrive at a total presentvalue of "savings" resulting fromthe proposed change. Then, in astep-by-step summary, the net costof implementing the change requiredto generate the savings is shown.First, the present value of all '

costs identified as new investmentcosts is shown. Added to this isthe present value of any existingassets to be used in implementingthe proposed new alternative.Then, the present value of anyitems released for other use(replaced assets) is subtracted, asis the present value of thesalvage/residual value of the newalternative. This results in a"net cost" of the new proposal.

Then the present value of thesavings (outlined in the first partof the A-i format) is entered. The

present value of any refurbishmenttype costs that would have beenrequired with a continuation of the

__ . status quo, is added to it.

8. Ranking Sensitivity ECONPACK has a sensitivity analysismodule. The automated sensitivitvanalysis routine of this programallows the analyst to system-atically determine the extent towhich changes in specified inputvalues produce changes in con-clusions. The analyst can directthe program to determine thepercentage change (up or down), in -a particular expense element or

group of expense elements, requiredto alter the rankings of the

alternatives.

Consider, for example, an EA cal-culation which shows that each oftwo proposed alternatives is lesscostly than the status quoalternative. Sensitivity analysisroutines can be set up to determinehow much larger one or more costitems in the proposed alternativeswould have to be for the status quoalternative to be least costly.Similarly, sensitivity routinescould be set up to determine howmuch of a reduction in one or morecost items comprising the existingalternative would be required tomake it the least cost.

The sensitivity analysis routinewill determine for any group ofselected cost items in one or morealternatives, for any selected num-ber of alternatives, the percentchinge required to result in aleast cost ranking other than theinitial least cost ranking. Such"what if" calculation scenarios are

potentially complex, but the usualcase, as noted above, is relativelysimple.

8. Ranking Sensitivity Choosing items to include in(Continued) sensitivity tests should be based

on common sense. For example,estimates of some expense items mayhave been made with less certainty'than others. Data sources may beweak or vague, or the estimate mayinvolve future projections whichare especially clouded withuncertainty. Such items deserve tobe tested for sensitivity.

The examples in the SampleSensitivity Analysis Blocks involvethe kind of scenario discussedabove. Alternative 1 is the statusquo, and alternatives 2 and 3 are

proposed changes, both involvingthe purchase of new equipment, anda different (and lower) set ofannually recurring costs. In theinitial ranking, both 2 and 3 wereless costly than 1. The twosensitivity blocks are set up todetermine how much more expensivethe new equipment would have to beor how much more the recurringannual cost would have to be,respectively, for the new alterna-tives to be more costly than thestatus quo. If the results showthat relatively small changes canproduce a switch in the ranking,further investigation is warranted.If, on the other hand, majorchanges would have to take place tochange the EA ranking results, thenfurther work would not beproductive, and there can be agreater degree of confidence in the . -

8. Ranking Sensitivity For example, SELECT ALTERNATIVES 1-3(Continued) 5, means that the analysis covers the

first three, and the fifth, alterna-tives in the input file. Alternative4 in this example is excluded from thesensitivity test. A reason for doingthis could be that while alternative 4is perhaps clearly the least costalternative, a strong possibility mayexist that the decision makingauthority may disfavor alternative 4for non-economic reasons. In such acase, the EA can anticipate thispossibility by establishing greaterconfidence regarding the rank orderof the remaining alternatives.

The alternative name may be used inplace of the alternative number inidentifying which alternatives areincluded in the sensitivity analysis.If this is done, the exact name mustbe used, as it appears in singlequotes in the alternative block. Ifshort, cryptic names have been used,this is a relatively easy way toselect alternatives for a sensitivitytest, with the added advantage thatthe input file becomes more self-documenting and more meaningful.

E. CHANGE [Required; CHANGE:follow with numbers,indicating the The change command is used to select

For example, CHANGE 1,1,2 meansthat expense item one and two inthe first alternative are to bechanged in the sensitivity test.If, in the same sensitivity test,items 3,4,5, and 6 in alternativethree were also to be changed, thefollowing two statements wouldsuffice:

CHANGE 1 1 2CHANGE 3 3-6

(NOTE: The second change commandcouid have been written CHANGE 3 3 .''4 5 6, but the shorthand notationusing the hyphen was used.)

AVOID including expense items whichinclude negative numbers in anECONPACK sensitivity analysis module.Unusual calculation sequence and com-parison logic may follow, which can bemisleading. The use of negativenumbers ir an EA expense item is aspecial case consideration. Sensi-tivity analysis regarding such expenseitems is most safely and clearlyaccomplished if done separately fromthe automated ECONPACKsensitivity analysis module.

F. LIMIT [Optional; LIMIT:used to alter theupper limit for the This command sets the maximum positivesensitivity change for the sensitivity test. Furanalysis.) example, LIMIT 100 means that the

expense elements involved in thesensitivity test (per the CHANGEcommand) are to be changed no morethan +100% (twice the initial value).

8. Ranking Sensitivity LIMIT: (Continued)(Continued)

If no limit is set, the maximumpositive change is assumed to be+200% (i.e., a tripling of theinitial value). The maximumnegative change is automaticallyset -100% (reduction to zero).

G. RANK [Required; RANK:follow with thealternative number The rank command selects theto be ranked at least alternative which the analystcost.] wishes to be ranked at least cost

in the sensitivity test. Forexample, RANK 2 indicates that thecomputer program will check to seehow much of a change in the Lindicated expense items will berequired to result in the secondalternative being least cost amongthose alternatives selected in the

sensitivity analysis block. Rank 3would cause the same exercise tooccur for the third alternative,etc.

H. TIME [Optional; if TIME:used, follow with thenumber of years for The TIME command selects the numberwhich the sensitivity of years, from the beginning of thetests are to be period of analysis, for which theperformed.] sensitivity tests are to be

performed. For example, if theperiod of analysis is 25, and TIME15 is entered, then the changetesting will be performed only forthe first 15 years in thu period ofanalysis. If this statement is notentered, the program executionperforms sensitivity test

CHAPTER 8

TRANSFERRING A COPY OF AN ECONPACK FILE ON TO A FORM IN THE DDFORM 1391 PROCESSOR ZO

This chapter contains detailed procedures for logging on to theDD Form 1391 Processor and transferring a copy of an ECONPACK fileinto the Special Requirements Paragraph 1 block on a form in theDD Form 1391 Processor.

Below is a quick version of the procedure as presented on thesystem in the ECONPACK HELP FACILITY:

To move an 'Output to the 1391' file to the correct SRP-1,utilize the following steps.

FOR TEMPECON USERS: Those users who utilize the ECONPACKprogram found at a 1391 time of day prompt,

1: Go to the correct 1391 form, to the SRP-1 block,

2: Enter the EDIT command,

3: At the E>, use a GETFILE command to copy the file

onto your form. (ex. GETFILE HUGH FT80F001)

FOR USERS OF ECONPACK: Those users who utilize the ECONPACKprogram found at the PAX MENU prompt,

1: Go to the DD1391 Time of Day Prompt and enter thecommand TEACUP2,

2: When prompted for, enter the filename and filetypeto be moved to the 1391 form, (ex. >HUGH FT8OFO01)

3: Go to the correct 1391 form, to the SRP-1 block,

4: Enter the EDIT command,

• 5: At the E>, use a GETFILE command to copy the fileonto your form, (ex. GETFILE HUGH FT80FO01)

6: NOTE: You may want to erase the file that youcreated on your 1391 disk. This is done by goingto a Time of Day Prompt and deleting the file.

TRANSFERRING A COPY OF AN ECONPACK FILE ON TO A FORM IN THE DD"FORM 1391 PROCESSOR

STEP 1. ESTABLISH TELEPHONE COMMUNICATION WITH THE COMPUTER. . -

The user must first establish telephone communicationwith the computer. This step is accomplished in variousways dependent upon the type of equipment being used aswell as how that equipment has been set up. Some usersmay simply have to turn the equipment on, hit aspecified key on the keyboard, and the communicationsline will automatically be accessed. Others may haveto dial the assigned telephone number, listen for ahigh-pitched sound, and then insert the telephonereceiver in the terminal's coupler or release aspecified button on the equipment's modem. Once theappropriate steps have been followed to establishtelephone communication with the computer, the systemwill quickly prompt the user to enter a "terminalidentifier". To prompt the user, the system willeither display a string of garbage-like characters oractually print the words "PLEASE TYPE YOUR TERMINALIDENTIFIER". The user should respond by entering the -

terminal identifier. A terminal identifier indicatesto the computer the type of equipment required tocommunicate with the user's terminal. If the wrongidentifier is entered, telephone communication will -

probably be terminated. [See Appendix B for a listof appropriate terminal identifiers for variousequipment.]

EXAMPLE:

Establish communications line. -.

PLEASE TYPE YOUR TERMINAL IDENTIFIER A

-3122-007-

8-2

_.7%* *.. .. ---.. *

STEP 2: "LOG ON" TO THE COMPUTER AND THE PAX SYSTEM.

Once the terminal identifier has been entered, thesystem will prompt for the System User ID and SystemPassword assigned the user's activity. These two words

* identify the user, the programs that user may access,and the activity to be billed for the session. If thecorrect System ID and Password are not entered within2 1/2 minutes after the user establishes telephonecommunication, the computer will automaticallydisconnect. The system then prompts for a "projectcode." The user should enter his/her initials. Thesystem then responds by printing the date and time theuser logged on to the computer.

Once logged on to the computer, the user has immediateaccess to the PAX System. The system indicates thePAXMAIL status for the user's System ID. PAXMAIL is afeature of the PAX System which allows PAX users tocommunicate with each other. The system then respondswith a "LOG ON" message which provides a variety ofinformation. Following the log on message is a displayof the PAX SYSTEM MENU in which the system lists thecomponents of the PAX System available to the user. Thenumber of components available to each System ID willvary. The system then prompts the user to make aselection.

EXAMPLE:

PLEASE LOG IN:[Enter your assigned System User ID.] (CR)

APPENDIX AGLOSSARY

Alternative: A course of action, means, or methods by which anobjective may be achieved.

Assumptions: Explicit statements used to describe the presentand future environment upon which the economic analysis is based.ECONPACK makes two assumptions: A 10% annual discount rate and noinflation. These may be changed if the housing feature isselected.

Baseline Date: The starting point for the economic analysis,beyond which decisions deal with future courses of action. It isthe "TODAY" in the analysis. May also be referred to as thebaseline year, base year, or analysis year 0.

Base Year: The first year in which initial investments are madeor initial costs are incurred.

Beneficial Occupancy Date (BOD): For facilities to be occupiedby the using agency, this is the date the facility is ready foroccupancy.

Benefits: Outputs or effectiveness expected to be received orachieved over time as a result of undertaking a proposed

investment.

Benefit/Cost Ratio (BCR): An economic indicator of efficiency,computed by dividing benefits by costs. When benefits arequantified in dollar terms, discount both the stream and the coststream to reflect the present value of future costs and benefits.

Breakeven Analysis: A procedure for evaluating alternatives interms of a common unknown variable. It involves solving for the

- value of the variable which will make the cumulative discountedcosts for the alternatives equivalent. This value is the break-even point.

Cash Flow Diagrams: A pictorial representatio: showing themagnitudes and timing of costs associated with an alternative.

Compound Interest: Interest which is computed on both theoriginal principle and its accrued interest.

Constant Dollars: An estimate is said to be in constant dollarsif costs are adjusted so they reflect the level of prices ofa base year.

Cost: A resource input to a project, program, or activityexpressed in dollar terms. See Expense Item.

Cost Avoidance: Savings realized by avoiding a planned,nonrecurring expenditure of resources. A cost avoidance can onlyoccur when adopting a nonstatus quo alternative.

Cost Benefit Analysis: A technique for assessing the range ofcosts and benefits associated with a given option, usually todetermine possibility. Costs are generally in monetary terms,but benefits need not be in monetary terms.

Cumulative Discounted Present Value: The sum total of thediscounted annual cost for the year in question and all preceding ,

years of the project.

Cumulative Net Discounted Present Value: See CumulativeDiscounted Present Value.

Current Dollars: When prior costs are stated in current dollars,the figures given are the actual amounts paid out. When futurecosts are stated in current dollars, the figures given are theactual amounts expected to be paid, including any amount causedby future price changes.

Discount Rate: A method of accounting for how much the value ofmoney changes over time. ECONPACK incorporates a 10% discountrate which reduces the worth of future dollars by 10% annually.An option exists to change this rate in certain type analyses.

Discounted Cumulative Annual Outlay: See Cumulative DiscountedPresent Value.

Discounted Payback: A technique for determining the time periodover which accumulated present value savings are enough to offsetthe total present value investment costs of a proposedalternative to the status quo.

Discounted Present Value: A monetary expenditure (or savings) 6multiplied by the discount rate. The resulting figure representsthe worth of the future amount in base year dollars.

Discounted Present Value Salvage: The salvage value of analternative discounted to represent its value in base yeardollars. ECONPACK discounts the salvage value from the finalyear of the project to the beginning of the start year.

Economic Analysis: A systematic method for quantifying the costsand or benefits of proposed projects. Basically, it consists ofsix steps: stating the objective, listing assumptions,defining alternatives, determining costs and benefits, comparingand ranking alternatives, and performing a sensitivity analysis.

A-2

,% a

Economic Life: The period of time over which the benefits froman alternative are expected to accrue. The economic life of analternative may be limited by its mission life or physical life.

Equivalent Uniform Annual Cost (UAC): See Uniform Annual Cost.

Expense Item: A term used by ECONPACK to represent a category ofexpenditures (costs). Each ECONPACK alternative must be composedof one or more expense items, which must be assigned a monetaryvalue for each year of the project's economic life. See Cost.

Historical Cost: The cost of any objective, based on actualasset outlay, determined after the fact. Any method of costdetermination may be used, but the sources of costs must bedocumented in the source derivation part of the output report.

Incremental Cost: The change in a cost associated with a changein the level of output.

Inflation: A persistent rise in the general level of prices overtime.

Input File: A file which lists the objective of an economicanalysis, alternatives, expense items, and other data needed toperform the analysis. '

Intangible Benefits: Those improvements in system performancewhich cannot be quantified in terms of dollars or other measures.

Interest: A price (or rent) charged for the use of money.

Investment Cost: One-time costs sociated with acquisition ofreal property, nonrecurring services, nonrecurring operations,and maintenance (start-up) costs and other one-time costs.Despite their one-time nature, investment costs may extend overperiods of more than one year.

Lead Time: The period of elapsed time between initial funding or

decision and the commencement of the economic life.

Life Cycle: The time from the beginning date of an alternative's

use to the end of the program/project life.

Maintenance and Repair Cost: The total of labor, material, andother costs of performing corrective and preventive maintenanceand repair on a facility and/or its systems and components.

Net Discounted Costs: Discounted dollar costs minus discounteddollar benefits (this can be negative value). ..

A-3 ,. .°.

• %

Nonrecurring Cost: Cost which occurs on a one-time basis; to bedistinguished from annually recurring costs.

Net Discounted Present Value: A cumulative discounted presentvalue amount that also accounts for the discounted present valueresidual amount.

Objectives: The result the decision maker wants to attain. Itis the desired end product of a program and must be stated in anunbiased way, e.g., "To house 400-additional personnel, "not" tobuild a 400-man barracks."

Output: The products, functions, tasks, services, orcapabilities for which an organization exists to produce,accomplish, attain, or maintain.

Output File: Once an input file has been run through ECONPACK,an output file representing the results of the analysis iscreated.

Output Measures: Useful descriptors of functions, tasks, ormissions performed by an organization expressed in relation tothose assigned.

Period of Analysis: The time span over which the economicanalysis takes place. This period usually corresponds to the Ceconomic life of the project.

Physical Life: The estimated number of years that a machine,piece of equipment, or building can physically be used inaccomplishing the function for which it was procured orconstructed.

Present Value: The worth of future benefits or costs expressed inthe value of money at the time of the project's base year.Present value is computed using an annual discount rate.

Present Worth: Same as present value.

Project: A major mission-oriented agency endeavor which fulfillsstatutory or executive requirements, and which is defined interms of the principal actions required to achieve a significantend objective.

Project Life: The lead time plus the economic life.

Ranking: The end result of ECONPACK's economic analysis.ECONPACK ranks each alternative sequentially from lowest cost tohighest cost.

A-4

Recurring Costs: Expenses for personnel, material consumed inuse, operating overhead, support services, and other items whichrecur annually in the execution of a given program or workeffort.

Residual Value: The remaining monetary value, if any, of analternative at a specified point in time.

Salvage Value: The remaining monetary value, if any, of aproject at the end of the project life. The value may benegative (i.e., it may cost dollars to remove the item).

Savings/Investment Ratio (SIR): The ratio of discounted futurecost savings (or avoidance) to the discounted investment costnecessary to effect those savings. An SIR of 1 indicates thatthe present value of savings is equal to the present value ofinvestment.

Sensitivity Analysis: A method for determining how changes inexpense item costs will affect the ranking of alternatives.

Sunk Cost: A past cost which is incurred before thebaseline date. Because sunk costs have been irrevocablyexpended or committed, they have no significance in choicebetween alternatives.

Tangible Benefits: Those improvements in system performancewhich can be quantified. They do not include savings inrecurring operating expenses. These savings are reflected asreductions in cost. 14%

Terminal Value: The expected value of land, buildings, orequipment at the end of economic life or project life.

Time Value of Money: The use of money costs money: a dollartoday is worth more than a dollar tomorrow because of theinterest costs related to expenditures and benefits which occurover time. Annual savings or cash inflows projected for tomorrowhave present values less than their undiscounted dollar values.

Total Annual Outlays: The sum total of all costs for a givenyear.

Uniform Annual Cost (UAC): See Uniform Annual Equivalent.

Uniform Annual Equivalent: The amount of money (discounted),which if paid in equal annual installments over the life of aproject, would pay for the project. The alternative with thelowest uniform annual equivalent amount is the least-costlyalternative.

Both of these commands cause the system to suppress the printingof output associated with the current command or program and1* issue the next prompt in the program's prompting sequence.[NOTE: KX(CR) may also be used but only in extreme cases. Thiscommand can result in the user being logged off the system. ]

B.3 Terminal Identifiers. Before a user can gain access to thehost computer, a specific alphabetic character must be entered toindicate the type of equipment being used to access the system.This character is identified as the TERMINAL IDENTIFIER. TableB-i lists the terminal identifier to be entered for specifictypes of terminals. Table B-2 lists terminal identifiersaccording to specific manufacturers and models. For equipmentnot listed in Table B-2, it is recommended the user first enterthe terminal identifier "A". If that is ineffective, theidentifier "E" should be entered.

B.4 Additional Communication Parameters. Some word processors

and microcomputers require additional information in order toconnect to the Tymshare System. Listed below are some additionalcommunication parameters.

Code ASCII

Duplex full

Parity mark or none

Parity bits - 1

Word length 7

Start bits 1

Stop bits 1".

Baud 300 or 1200

Modem Many phone numbers are compatiblewith any 300 baud mode, 1200 baudBELL, and Vadic modems. (Check phonenumbers listed in PAX NEWSLETTERS).

End of line -5-

(transmit toTYMSHARE) CR

End of line(transmit toTYMSHARE) CRLF (LF)

Some terminals require the use of control characters before theuser enters the System User ID at the PLEASE LOG IN: prompt.The control characters are accessed by simultaneously depressingthe control (CTRL) key and the alphabet key.

CTRL X Entered for terminal transmission from papertape, cassette, internal buffer, or disk torequest that TYMSHARE control the flow ofterminal output with X-ON (DC-I, CTRL Q) andX-OFF (DC-3, CTRL S) to prevent data loss. F

CTRL H Initiates half duplex operation by suppressingTYMSHARE echoing of input characters.

CTRL P Provides for even parity for computer outputrather than no parity.

%I

CTRL R Allows terminal control of received data flowwith X-ON (DC-I, CTRL Q) to signal terminalready and X-OFF (DC-3, CTRL S) to signal .terminal busy.

B.5 Line Noise. Sometimes a user may have trouble with noise, ri.e., random characters showing up in the print. Often thesource of the noise can be very difficult to determine.Presented below are some possible solutions to noise problems:

Poor connection Try hanging up the phone andredialing.

Poor phone line Some buildings have poor phone lines.If possible, try using a phone in adifferent building.

Noisy power supply Large ventilating units, welders,motors, etc. can transmit electricalnoise over power lines to computerequipment. The computer terminalshould be on a separate circuit. Tryoperating the terminal in a differentlocation. An isolation transformermay help.

Installation PBX Some installation switchboards add(switchboard) noise to telephone lines. A direct

off post line may imprcve the noiseproblem. A direct line is one wherea special access code is notrequired to dial a commercialnumber.

1200 baud 1200 baud modems are quite sensitiveto noise. If there is a noiseproblem, try using a 300 baud modem.

Acoustical coupling - The carbon microphone supplied withthe telephone may not be good enoughfor computer communications. Tryswitching the microphone with anothertelephone. Also, electret condenserreplacement microphones are availablewhich are better than carbonmicrophones for use with a modem.
