Considerable resources are needed when implementing the ERP project so it is necessary to evaluate its performance Firstly theevaluation index system of implementation performance of the ERP project was built and an Analytic Network Process (ANP)which can fully take the relationship between evaluation indexes into account was employed to determine the index weightSecondly an improved matter-element extension model which can overcome the limitations and inadequacies of traditionalmatter-element extension model when performing the comprehensive evaluation was proposed to evaluate the implementationperformance of the ERP project Finally taking an enterprisersquos ERP project as an example a comprehensive evaluation was doneand the empirical analysis result shows that this proposed hybrid evaluation model is feasible and practical
1 Introduction
The Enterprise Resource Planning (ERP) system which isbuilt on the information technology and systematic manage-ment thoughts can provide a decision-making managementplatform for enterprisersquosmanagement teamand staffTheERPsystem plays a significant role in improving the business pro-cesses and competitiveness of an enterprise The implemen-tation of ERP changes the organizational and business modewhich brings a huge impact on each enterprisersquos departmentSince considerable enterprise resources are needed whenimplementing ERP project it is quite necessary to build areasonable and effective comprehensive evaluationmethod toevaluate the performance of ERP project
Many evaluation models have been used to evaluateproject performance such as analytic hierarchy process(AHP) [1] fuzzy analytic hierarchy process (FAHP) [2]data envelopment analytic hierarchy process (DEAHP) [3]balanced scorecard (BS) [4] and neural network analysismethod [5] In addition many studies have also been con-ducted on evaluating ERPproject performance Chen andLin
[6] proposed a fuzzy linguistic performance indicator basedon network flowmodel to assess the performance of ERP sys-tems Zhan et al [7] presented an evaluation model based onthe Triangle Whiten Function Xu [8] used an AHP methodto evaluate the performance of ERP considering the feedbackand dependence factors Razmi et al [9] proposed a fuzzyanalytic hierarchy process model (FAHP) which combinesfuzzy theory with analytic hierarchy process to evaluate theERPproject Chang et al [10] constructed a conceptualmodelto measure the performance and competitive advantages ofERP from a supply chain management perspective Hanet al[11] used ABCDmonitoring table and SPA project evaluationmethod to assess the ERP projectThe AHPmethod does notconsider the relationship between different indexes of controllevel in the index system which weakens the objectivity ofthe evaluation result BP neural network evaluation methoddoes not determine the index weight but it requires a largeamount of training samples Although data envelopmentanalysis method is relatively objective it is not suitable forqualitative analysis ABCDmonitoring table and SPA projectevaluation method can cover a wide range of indexes but

the quantification of indexes is very difficult Therefore amore practical and objective evaluation method needs to beproposed
The matter-element extension analysis model transformspractical problem into a formal one using matter-elementand extension theory and presents grade of things throughcalculating the correlation between the matter-element tobe evaluated and each level In addition the matter-elementextension analysis can be also used though there are fewsamples Li and Zhang [12] assessed the performance of theemployees through establishing a qualitative and quantitativeperformance evaluationmethod based on thematter-elementextension theory and results shows that this method is moreobjective Zhou [13] established a performance evaluationmodel based on matter-element and correlation functionQualitative and quantitative evaluations on the performanceof conglomerate merger were done However if index valueexceeds the controlled field correlation function cannot becalculated Therefore the traditional matter-element exten-sion model needs to be improved
In order to evaluate the performance of enterprisersquos ERPproject a hybrid evaluation model combining ANP andimproved matter-element extension model was proposedFirstly the evaluation index system was built secondly anANP was used to determine the weight of each index whichfully took the relationship among various indicators intoaccount and then an improved matter-element extensionmodel which can overcome the limitations and inadequaciesof traditional matter-element extensionmodel was proposedFinally taking an enterprisersquos ERP project as an example thecomprehensive evaluation was done and empirical analysisresults show that this hybrid evaluation model is feasible andpractical
2 Building the Performance Evaluation IndexSystem of ERP Project
21 The Implementation Effect of ERP Project ERP systemrequires a large number of enterprisersquos resources and changesthe organizational and business mode in enterprise Theimplementation of ERP project brings multiple effects onenterprise
ERP project involves many aspects of enterprise man-agement such as production management financial man-agement sales management purchasing management andinventory management [14] Therefore the implementationof ERP project not only relies on IT departments but alsorelies on the collaboration of other departments in enterpriseManagers must be familiar with management and technicalbusiness based on ERP Tasks are completed by professionalstaff so the overall quality of employees production effi-ciency and production capacity will increase correspond-ingly
Based on the financial system financial capital operationreaches a dynamic equilibrium Meanwhile turnover rate ofthe total funds and enterprisersquos return on equity improveaccordingly
The implementation of the procurement and inventorysystem provides many inventory analysis methods for thesupply department This system can not only ensure theprocurement of purchased parts timely but also improveinventory levels which can reduce the backlog of inventoryfunds and accelerate the efficiency timeliness and accuracyof the inventory turnover of delivery The implementation ofprocurement and inventory system will raise overall level ofoperational management market share and new customeracquisition rate
A good operation of ERP system makes data integralaccurate consistent and timely Data sharing becomes accu-rate and timely accordingly ERP project can also supportbusiness decision improve forecasting production plan andensure a stable and efficient operation in an enterprise
22 Building the Evaluation Index System In order to evaluatethe implementation performance of enterprisersquos ERP projectsaccurately it is necessary to establish a reasonable evaluationindex system and grading standard Based on former analysisabout the effect of implementing ERP system we use Delphimethod to build a performance index system of ERP project[5 14] The finance management operations managementand customer management are criterion layer indexes Inaddition 11 extended indexes are concluded in the subcrite-rion layer The index system is shown in Figure 1
3 The Establishment of the HybridEvaluation Model
31 Basic Theory of Extension Analysis Matter-element ex-tension model [13 15 16] is based on matter-element theoryand extension set theory We can determine the level of onething through establishing classical field controlled fieldevaluation level and correlation function However there aresome limitations and deficiencies
(1) When any matter-element index value beyond itscontrolled field the correlation function values areunavailable so thismodel cannot perform evaluation
(2) The level of one thing is obtained by calculating cor-relation function in this model From the perspectiveof algorithm correlation degree can be regarded as anextension of membership degree in fuzzy mathemat-ics so the correlation degree principle is equivalentto the maximummembership principle [15] In somecase however the maximum membership principlecannot reflect the ambiguity of objectrsquos boundary Itwill lose information and lead to the deviation ofresults
Aiming at the limitation of (1) point the classical domainand the matter-element to be evaluated should be normal-ized Aiming at the limitation of (2) point the maximummembership degree criterion should be replaced by thecorrelation degree criterion

method [13 15] is as follows first of all the object is dividedinto119895 levels and the range of each level is determined bydatabase or experts secondly determine the weight of eachindex Finally calculate the closeness degree and determinethe level of matter-element
Matter element is the logic unit of matter-element exten-sion model it uses an ordered triple 119877 = (119875 119862 119881) to describethings 119875 119862 119881 represent the name the characters and thevalue of one thing respectively The basic steps of improvedmatter-element extension model are as follows

(2) Normalization [16]
When an actual value of index exceeds the controlledfield the correlation function cannot be calculated namelythe denominator is zero In this case matter-element andextension model cannot be used to evaluate the performanceof ERP project Therefore the classical domain and matter-element evaluation should be normalized

(3) Weight determination
The Weight of the evaluation index directly affects thequality and feasibility of a comprehensive evaluation Sothe determination of index weight is very important to theresult of enterprise performance comprehensive evaluationSince the evaluation index system is complex and related anAnalytic Network Process is used to determine the weight ofeach index which can fully take all characters of indexes intoaccount
(4) Establish and calculate the closeness function
Zhang [17] used closeness degree criteria instead of max-imum degree of membership criteria and made a theoreticalanalysis He put forward an asymmetric closeness formula(119901 = 1) as follows
119873 = 1 minus1
119899 (119899 + 1)

where 119873 represents the value of closeness function 119863represents the distance 119908119894 is the weight
The value of closeness function about each index of thematter element to be evaluated with each level is calculatedas follows
119873119895 (1199010) = 1 minus1

33 Analytic Network Process Method Analytic NetworkProcess [18ndash20] was developed from analytic hierarchyprocess This method fully considers the interdependencebetween elements mutual influence between elements in thesame level and dominance relation from the lower level Allelements form a network structure of ANP An ANP consistsof two parts The first part is the control layer includinggoal and criterion In this layer each criterion is independentand controlled only by target element The second part isthe network layer it is controlled by control layer and theelements in the network layer influence each other (Figure 2)
331 Basic Operation Process Suppose the elements in thecontrol layer are 1198611 1198612 119861119898 and the elements in the net-work layer are 1198621 1198622 119862119899 119862119894 consisting of 1198901198941 1198901198942 119890119894119899Taking 119861119896 as a principle and 119890119894119896 as a subprinciple we comparethe influence of 119890119894119896 from other elements in the 119862119894 formthe comparison matrix119882119894119895 and calculate the weight matrixrespectively In a similar way we can obtain the influence

Taking119861119896 as standardwe compare the influence degree ofeach element to119862119894 and we can get weightedmatrix as follows

The matrix 119860 is multiplied by the matrix 119882 then weget the weighted matrix 119882 = 119886119894119895119882119894119895 119894 = 1 2 119899 119895 =

34 The Calculation Process of the ANP-Improved Matter-Element Extension Model In summary the steps of compre-hensive evaluation based on the ANP and improved matter-element method are as follows
Step 1 Determine the classical domain controlled field andmatter element to be evaluated
Step 2 Normalize the classical domain controlled field andmatter element to be evaluated when the measure data ofindex exceeds controlled field
Step 3 Calculate the index weight based on the ANP
Step 4 Calculate the value of closeness function of eachgrade

45 Sensitivity Analysis Sensitivity analysis is performedaccording to the performance evaluation index systemof ERPproject When the index value or weight of index changesits level variable characteristic value 119895lowast also changes corre-spondinglyWhen the index value changes by 5 10 minus10minus20 minus30 minus40 minus50 respectively the level variablecharacteristic value 119895lowast changes as shown in Figure 2 Whenthe weight of index changes by plusmn10 plusmn20 plusmn30 plusmn40or plusmn50 the level variable characteristic value 119895lowast changescorrespondingly just as the Figure 3
As we can see from Figure 7 the project performanceindexes 1198881 1198882 1198888 11988811 have large effect on the evaluation resultswhich means that the sensitivity of 1198881 1198882 1198888 11988811 is very strongFor example when the 11988811 index changes the range ofthe 119895lowast value varies from 12 to 18 Although ERP projectperformance level does not change the level gradually tendsto ldquogoodrdquo level from ldquohighrdquo level With the change of index1198883 1198884 1198885 1198886 1198887 1198889 11988810 the 119895
lowast value changes a little from 15 to165 It indicates that the variation of index value will notchange the level which the project performance tends to orbelongs to
In Figure 8 we can know that the change of 1198881 and 11988811indexes affects the 119895lowast value obviously but other indexes haveless effect on the 119895lowast value In a word 1198881 and 11988811 are sensitiveindexes in the ERP project performance evaluation

2 Mathematical Problems in Engineering
the quantification of indexes is very difficult Therefore amore practical and objective evaluation method needs to beproposed
The matter-element extension analysis model transformspractical problem into a formal one using matter-elementand extension theory and presents grade of things throughcalculating the correlation between the matter-element tobe evaluated and each level In addition the matter-elementextension analysis can be also used though there are fewsamples Li and Zhang [12] assessed the performance of theemployees through establishing a qualitative and quantitativeperformance evaluationmethod based on thematter-elementextension theory and results shows that this method is moreobjective Zhou [13] established a performance evaluationmodel based on matter-element and correlation functionQualitative and quantitative evaluations on the performanceof conglomerate merger were done However if index valueexceeds the controlled field correlation function cannot becalculated Therefore the traditional matter-element exten-sion model needs to be improved
In order to evaluate the performance of enterprisersquos ERPproject a hybrid evaluation model combining ANP andimproved matter-element extension model was proposedFirstly the evaluation index system was built secondly anANP was used to determine the weight of each index whichfully took the relationship among various indicators intoaccount and then an improved matter-element extensionmodel which can overcome the limitations and inadequaciesof traditional matter-element extensionmodel was proposedFinally taking an enterprisersquos ERP project as an example thecomprehensive evaluation was done and empirical analysisresults show that this hybrid evaluation model is feasible andpractical
2 Building the Performance Evaluation IndexSystem of ERP Project
21 The Implementation Effect of ERP Project ERP systemrequires a large number of enterprisersquos resources and changesthe organizational and business mode in enterprise Theimplementation of ERP project brings multiple effects onenterprise
ERP project involves many aspects of enterprise man-agement such as production management financial man-agement sales management purchasing management andinventory management [14] Therefore the implementationof ERP project not only relies on IT departments but alsorelies on the collaboration of other departments in enterpriseManagers must be familiar with management and technicalbusiness based on ERP Tasks are completed by professionalstaff so the overall quality of employees production effi-ciency and production capacity will increase correspond-ingly
Based on the financial system financial capital operationreaches a dynamic equilibrium Meanwhile turnover rate ofthe total funds and enterprisersquos return on equity improveaccordingly
The implementation of the procurement and inventorysystem provides many inventory analysis methods for thesupply department This system can not only ensure theprocurement of purchased parts timely but also improveinventory levels which can reduce the backlog of inventoryfunds and accelerate the efficiency timeliness and accuracyof the inventory turnover of delivery The implementation ofprocurement and inventory system will raise overall level ofoperational management market share and new customeracquisition rate
A good operation of ERP system makes data integralaccurate consistent and timely Data sharing becomes accu-rate and timely accordingly ERP project can also supportbusiness decision improve forecasting production plan andensure a stable and efficient operation in an enterprise
22 Building the Evaluation Index System In order to evaluatethe implementation performance of enterprisersquos ERP projectsaccurately it is necessary to establish a reasonable evaluationindex system and grading standard Based on former analysisabout the effect of implementing ERP system we use Delphimethod to build a performance index system of ERP project[5 14] The finance management operations managementand customer management are criterion layer indexes Inaddition 11 extended indexes are concluded in the subcrite-rion layer The index system is shown in Figure 1
3 The Establishment of the HybridEvaluation Model
31 Basic Theory of Extension Analysis Matter-element ex-tension model [13 15 16] is based on matter-element theoryand extension set theory We can determine the level of onething through establishing classical field controlled fieldevaluation level and correlation function However there aresome limitations and deficiencies
(1) When any matter-element index value beyond itscontrolled field the correlation function values areunavailable so thismodel cannot perform evaluation
(2) The level of one thing is obtained by calculating cor-relation function in this model From the perspectiveof algorithm correlation degree can be regarded as anextension of membership degree in fuzzy mathemat-ics so the correlation degree principle is equivalentto the maximummembership principle [15] In somecase however the maximum membership principlecannot reflect the ambiguity of objectrsquos boundary Itwill lose information and lead to the deviation ofresults
Aiming at the limitation of (1) point the classical domainand the matter-element to be evaluated should be normal-ized Aiming at the limitation of (2) point the maximummembership degree criterion should be replaced by thecorrelation degree criterion

Figure 1 The performance evaluation index system of ERP project
method [13 15] is as follows first of all the object is dividedinto119895 levels and the range of each level is determined bydatabase or experts secondly determine the weight of eachindex Finally calculate the closeness degree and determinethe level of matter-element
Matter element is the logic unit of matter-element exten-sion model it uses an ordered triple 119877 = (119875 119862 119881) to describethings 119875 119862 119881 represent the name the characters and thevalue of one thing respectively The basic steps of improvedmatter-element extension model are as follows

(2) Normalization [16]
When an actual value of index exceeds the controlledfield the correlation function cannot be calculated namelythe denominator is zero In this case matter-element andextension model cannot be used to evaluate the performanceof ERP project Therefore the classical domain and matter-element evaluation should be normalized

(3) Weight determination
The Weight of the evaluation index directly affects thequality and feasibility of a comprehensive evaluation Sothe determination of index weight is very important to theresult of enterprise performance comprehensive evaluationSince the evaluation index system is complex and related anAnalytic Network Process is used to determine the weight ofeach index which can fully take all characters of indexes intoaccount
(4) Establish and calculate the closeness function
Zhang [17] used closeness degree criteria instead of max-imum degree of membership criteria and made a theoreticalanalysis He put forward an asymmetric closeness formula(119901 = 1) as follows
119873 = 1 minus1
119899 (119899 + 1)
119899

where 119873 represents the value of closeness function 119863represents the distance 119908119894 is the weight
The value of closeness function about each index of thematter element to be evaluated with each level is calculatedas follows

33 Analytic Network Process Method Analytic NetworkProcess [18ndash20] was developed from analytic hierarchyprocess This method fully considers the interdependencebetween elements mutual influence between elements in thesame level and dominance relation from the lower level Allelements form a network structure of ANP An ANP consistsof two parts The first part is the control layer includinggoal and criterion In this layer each criterion is independentand controlled only by target element The second part isthe network layer it is controlled by control layer and theelements in the network layer influence each other (Figure 2)
331 Basic Operation Process Suppose the elements in thecontrol layer are 1198611 1198612 119861119898 and the elements in the net-work layer are 1198621 1198622 119862119899 119862119894 consisting of 1198901198941 1198901198942 119890119894119899Taking 119861119896 as a principle and 119890119894119896 as a subprinciple we comparethe influence of 119890119894119896 from other elements in the 119862119894 formthe comparison matrix119882119894119895 and calculate the weight matrixrespectively In a similar way we can obtain the influence

Taking119861119896 as standardwe compare the influence degree ofeach element to119862119894 and we can get weightedmatrix as follows

As we can see from Figure 7 the project performanceindexes 1198881 1198882 1198888 11988811 have large effect on the evaluation resultswhich means that the sensitivity of 1198881 1198882 1198888 11988811 is very strongFor example when the 11988811 index changes the range ofthe 119895lowast value varies from 12 to 18 Although ERP projectperformance level does not change the level gradually tendsto ldquogoodrdquo level from ldquohighrdquo level With the change of index1198883 1198884 1198885 1198886 1198887 1198889 11988810 the 119895
lowast value changes a little from 15 to165 It indicates that the variation of index value will notchange the level which the project performance tends to orbelongs to
In Figure 8 we can know that the change of 1198881 and 11988811indexes affects the 119895lowast value obviously but other indexes haveless effect on the 119895lowast value In a word 1198881 and 11988811 are sensitiveindexes in the ERP project performance evaluation
5 Conclusions
ERP system has been introduced into enterprises for manyyears It is necessary to evaluate the performance of theERP project in enterprise However the factors which affectthe performance of ERP project are complex and relatedSo a hybrid evaluation method of ERP project performancewhich considers these peculiarities was proposed In order
Mathematical Problems in Engineering 9
to analyze the performance of ERP project an index sys-tem of comprehensive benefit evaluation including financecustomer and operation management is established in thispaper An ANP was proposed to determine the weight ofeach index which fully took the relationship between variousindicators into account Due to the limitations and inadequa-cies of traditionalmatter-element extensionmodel when per-forming the comprehensive evaluation an improved matter-element extensionmodel was proposed And then taking oneenterprisersquos ERP project as an example the comprehensiveevaluation was done The empirical analysis results show theperformance of ERPproject in our case belongs to ldquohighrdquo leveland our proposed hybrid evaluation model is feasible andpractical Finally a sensitivity analysis is performed to findsensitive index in the ERP project evaluation The analysisresults show that total asset turnover ratio and data transferefficiency are sensitive indexes so this enterprise should paymore attention to them

Figure 1 The performance evaluation index system of ERP project
method [13 15] is as follows first of all the object is dividedinto119895 levels and the range of each level is determined bydatabase or experts secondly determine the weight of eachindex Finally calculate the closeness degree and determinethe level of matter-element
Matter element is the logic unit of matter-element exten-sion model it uses an ordered triple 119877 = (119875 119862 119881) to describethings 119875 119862 119881 represent the name the characters and thevalue of one thing respectively The basic steps of improvedmatter-element extension model are as follows

(2) Normalization [16]
When an actual value of index exceeds the controlledfield the correlation function cannot be calculated namelythe denominator is zero In this case matter-element andextension model cannot be used to evaluate the performanceof ERP project Therefore the classical domain and matter-element evaluation should be normalized

(3) Weight determination
The Weight of the evaluation index directly affects thequality and feasibility of a comprehensive evaluation Sothe determination of index weight is very important to theresult of enterprise performance comprehensive evaluationSince the evaluation index system is complex and related anAnalytic Network Process is used to determine the weight ofeach index which can fully take all characters of indexes intoaccount
(4) Establish and calculate the closeness function
Zhang [17] used closeness degree criteria instead of max-imum degree of membership criteria and made a theoreticalanalysis He put forward an asymmetric closeness formula(119901 = 1) as follows
119873 = 1 minus1
119899 (119899 + 1)
119899

where 119873 represents the value of closeness function 119863represents the distance 119908119894 is the weight
The value of closeness function about each index of thematter element to be evaluated with each level is calculatedas follows
119873119895 (1199010) = 1 minus1
119899 (119899 + 1)

33 Analytic Network Process Method Analytic NetworkProcess [18ndash20] was developed from analytic hierarchyprocess This method fully considers the interdependencebetween elements mutual influence between elements in thesame level and dominance relation from the lower level Allelements form a network structure of ANP An ANP consistsof two parts The first part is the control layer includinggoal and criterion In this layer each criterion is independentand controlled only by target element The second part isthe network layer it is controlled by control layer and theelements in the network layer influence each other (Figure 2)
331 Basic Operation Process Suppose the elements in thecontrol layer are 1198611 1198612 119861119898 and the elements in the net-work layer are 1198621 1198622 119862119899 119862119894 consisting of 1198901198941 1198901198942 119890119894119899Taking 119861119896 as a principle and 119890119894119896 as a subprinciple we comparethe influence of 119890119894119896 from other elements in the 119862119894 formthe comparison matrix119882119894119895 and calculate the weight matrixrespectively In a similar way we can obtain the influence

Taking119861119896 as standardwe compare the influence degree ofeach element to119862119894 and we can get weightedmatrix as follows

The matrix 119860 is multiplied by the matrix 119882 then weget the weighted matrix 119882 = 119886119894119895119882119894119895 119894 = 1 2 119899 119895 =

34 The Calculation Process of the ANP-Improved Matter-Element Extension Model In summary the steps of compre-hensive evaluation based on the ANP and improved matter-element method are as follows
Step 1 Determine the classical domain controlled field andmatter element to be evaluated
Step 2 Normalize the classical domain controlled field andmatter element to be evaluated when the measure data ofindex exceeds controlled field
Step 3 Calculate the index weight based on the ANP
Step 4 Calculate the value of closeness function of eachgrade
The119873119895lowast(1199010) = max119873119895lowast(1199010) (119895 = 1 2 119898) means thatthe matter element to be evaluated belongs to the 119895lowastth level

45 Sensitivity Analysis Sensitivity analysis is performedaccording to the performance evaluation index systemof ERPproject When the index value or weight of index changesits level variable characteristic value 119895lowast also changes corre-spondinglyWhen the index value changes by 5 10 minus10minus20 minus30 minus40 minus50 respectively the level variablecharacteristic value 119895lowast changes as shown in Figure 2 Whenthe weight of index changes by plusmn10 plusmn20 plusmn30 plusmn40or plusmn50 the level variable characteristic value 119895lowast changescorrespondingly just as the Figure 3
As we can see from Figure 7 the project performanceindexes 1198881 1198882 1198888 11988811 have large effect on the evaluation resultswhich means that the sensitivity of 1198881 1198882 1198888 11988811 is very strongFor example when the 11988811 index changes the range ofthe 119895lowast value varies from 12 to 18 Although ERP projectperformance level does not change the level gradually tendsto ldquogoodrdquo level from ldquohighrdquo level With the change of index1198883 1198884 1198885 1198886 1198887 1198889 11988810 the 119895
lowast value changes a little from 15 to165 It indicates that the variation of index value will notchange the level which the project performance tends to orbelongs to
In Figure 8 we can know that the change of 1198881 and 11988811indexes affects the 119895lowast value obviously but other indexes haveless effect on the 119895lowast value In a word 1198881 and 11988811 are sensitiveindexes in the ERP project performance evaluation
5 Conclusions
ERP system has been introduced into enterprises for manyyears It is necessary to evaluate the performance of theERP project in enterprise However the factors which affectthe performance of ERP project are complex and relatedSo a hybrid evaluation method of ERP project performancewhich considers these peculiarities was proposed In order
Mathematical Problems in Engineering 9
to analyze the performance of ERP project an index sys-tem of comprehensive benefit evaluation including financecustomer and operation management is established in thispaper An ANP was proposed to determine the weight ofeach index which fully took the relationship between variousindicators into account Due to the limitations and inadequa-cies of traditionalmatter-element extensionmodel when per-forming the comprehensive evaluation an improved matter-element extensionmodel was proposed And then taking oneenterprisersquos ERP project as an example the comprehensiveevaluation was done The empirical analysis results show theperformance of ERPproject in our case belongs to ldquohighrdquo leveland our proposed hybrid evaluation model is feasible andpractical Finally a sensitivity analysis is performed to findsensitive index in the ERP project evaluation The analysisresults show that total asset turnover ratio and data transferefficiency are sensitive indexes so this enterprise should paymore attention to them

33 Analytic Network Process Method Analytic NetworkProcess [18ndash20] was developed from analytic hierarchyprocess This method fully considers the interdependencebetween elements mutual influence between elements in thesame level and dominance relation from the lower level Allelements form a network structure of ANP An ANP consistsof two parts The first part is the control layer includinggoal and criterion In this layer each criterion is independentand controlled only by target element The second part isthe network layer it is controlled by control layer and theelements in the network layer influence each other (Figure 2)
331 Basic Operation Process Suppose the elements in thecontrol layer are 1198611 1198612 119861119898 and the elements in the net-work layer are 1198621 1198622 119862119899 119862119894 consisting of 1198901198941 1198901198942 119890119894119899Taking 119861119896 as a principle and 119890119894119896 as a subprinciple we comparethe influence of 119890119894119896 from other elements in the 119862119894 formthe comparison matrix119882119894119895 and calculate the weight matrixrespectively In a similar way we can obtain the influence

Taking119861119896 as standardwe compare the influence degree ofeach element to119862119894 and we can get weightedmatrix as follows

The matrix 119860 is multiplied by the matrix 119882 then weget the weighted matrix 119882 = 119886119894119895119882119894119895 119894 = 1 2 119899 119895 =

34 The Calculation Process of the ANP-Improved Matter-Element Extension Model In summary the steps of compre-hensive evaluation based on the ANP and improved matter-element method are as follows
Step 1 Determine the classical domain controlled field andmatter element to be evaluated
Step 2 Normalize the classical domain controlled field andmatter element to be evaluated when the measure data ofindex exceeds controlled field
Step 3 Calculate the index weight based on the ANP
Step 4 Calculate the value of closeness function of eachgrade

45 Sensitivity Analysis Sensitivity analysis is performedaccording to the performance evaluation index systemof ERPproject When the index value or weight of index changesits level variable characteristic value 119895lowast also changes corre-spondinglyWhen the index value changes by 5 10 minus10minus20 minus30 minus40 minus50 respectively the level variablecharacteristic value 119895lowast changes as shown in Figure 2 Whenthe weight of index changes by plusmn10 plusmn20 plusmn30 plusmn40or plusmn50 the level variable characteristic value 119895lowast changescorrespondingly just as the Figure 3
As we can see from Figure 7 the project performanceindexes 1198881 1198882 1198888 11988811 have large effect on the evaluation resultswhich means that the sensitivity of 1198881 1198882 1198888 11988811 is very strongFor example when the 11988811 index changes the range ofthe 119895lowast value varies from 12 to 18 Although ERP projectperformance level does not change the level gradually tendsto ldquogoodrdquo level from ldquohighrdquo level With the change of index1198883 1198884 1198885 1198886 1198887 1198889 11988810 the 119895
lowast value changes a little from 15 to165 It indicates that the variation of index value will notchange the level which the project performance tends to orbelongs to
In Figure 8 we can know that the change of 1198881 and 11988811indexes affects the 119895lowast value obviously but other indexes haveless effect on the 119895lowast value In a word 1198881 and 11988811 are sensitiveindexes in the ERP project performance evaluation
5 Conclusions
ERP system has been introduced into enterprises for manyyears It is necessary to evaluate the performance of theERP project in enterprise However the factors which affectthe performance of ERP project are complex and relatedSo a hybrid evaluation method of ERP project performancewhich considers these peculiarities was proposed In order
Mathematical Problems in Engineering 9
to analyze the performance of ERP project an index sys-tem of comprehensive benefit evaluation including financecustomer and operation management is established in thispaper An ANP was proposed to determine the weight ofeach index which fully took the relationship between variousindicators into account Due to the limitations and inadequa-cies of traditionalmatter-element extensionmodel when per-forming the comprehensive evaluation an improved matter-element extensionmodel was proposed And then taking oneenterprisersquos ERP project as an example the comprehensiveevaluation was done The empirical analysis results show theperformance of ERPproject in our case belongs to ldquohighrdquo leveland our proposed hybrid evaluation model is feasible andpractical Finally a sensitivity analysis is performed to findsensitive index in the ERP project evaluation The analysisresults show that total asset turnover ratio and data transferefficiency are sensitive indexes so this enterprise should paymore attention to them

44 Determine the Performance Rating Since 1198731(1199010) =maxN119895(1199010) = 0999482 119895 = 1 2 3 4 it is shown that theperformance level of ERP project in this enterprise belongsto ldquohighrdquo
45 Sensitivity Analysis Sensitivity analysis is performedaccording to the performance evaluation index systemof ERPproject When the index value or weight of index changesits level variable characteristic value 119895lowast also changes corre-spondinglyWhen the index value changes by 5 10 minus10minus20 minus30 minus40 minus50 respectively the level variablecharacteristic value 119895lowast changes as shown in Figure 2 Whenthe weight of index changes by plusmn10 plusmn20 plusmn30 plusmn40or plusmn50 the level variable characteristic value 119895lowast changescorrespondingly just as the Figure 3
As we can see from Figure 7 the project performanceindexes 1198881 1198882 1198888 11988811 have large effect on the evaluation resultswhich means that the sensitivity of 1198881 1198882 1198888 11988811 is very strongFor example when the 11988811 index changes the range ofthe 119895lowast value varies from 12 to 18 Although ERP projectperformance level does not change the level gradually tendsto ldquogoodrdquo level from ldquohighrdquo level With the change of index1198883 1198884 1198885 1198886 1198887 1198889 11988810 the 119895
lowast value changes a little from 15 to165 It indicates that the variation of index value will notchange the level which the project performance tends to orbelongs to
In Figure 8 we can know that the change of 1198881 and 11988811indexes affects the 119895lowast value obviously but other indexes haveless effect on the 119895lowast value In a word 1198881 and 11988811 are sensitiveindexes in the ERP project performance evaluation
5 Conclusions
ERP system has been introduced into enterprises for manyyears It is necessary to evaluate the performance of theERP project in enterprise However the factors which affectthe performance of ERP project are complex and relatedSo a hybrid evaluation method of ERP project performancewhich considers these peculiarities was proposed In order
Mathematical Problems in Engineering 9
to analyze the performance of ERP project an index sys-tem of comprehensive benefit evaluation including financecustomer and operation management is established in thispaper An ANP was proposed to determine the weight ofeach index which fully took the relationship between variousindicators into account Due to the limitations and inadequa-cies of traditionalmatter-element extensionmodel when per-forming the comprehensive evaluation an improved matter-element extensionmodel was proposed And then taking oneenterprisersquos ERP project as an example the comprehensiveevaluation was done The empirical analysis results show theperformance of ERPproject in our case belongs to ldquohighrdquo leveland our proposed hybrid evaluation model is feasible andpractical Finally a sensitivity analysis is performed to findsensitive index in the ERP project evaluation The analysisresults show that total asset turnover ratio and data transferefficiency are sensitive indexes so this enterprise should paymore attention to them

As we can see from Figure 7 the project performanceindexes 1198881 1198882 1198888 11988811 have large effect on the evaluation resultswhich means that the sensitivity of 1198881 1198882 1198888 11988811 is very strongFor example when the 11988811 index changes the range ofthe 119895lowast value varies from 12 to 18 Although ERP projectperformance level does not change the level gradually tendsto ldquogoodrdquo level from ldquohighrdquo level With the change of index1198883 1198884 1198885 1198886 1198887 1198889 11988810 the 119895
lowast value changes a little from 15 to165 It indicates that the variation of index value will notchange the level which the project performance tends to orbelongs to
In Figure 8 we can know that the change of 1198881 and 11988811indexes affects the 119895lowast value obviously but other indexes haveless effect on the 119895lowast value In a word 1198881 and 11988811 are sensitiveindexes in the ERP project performance evaluation
5 Conclusions

44 Determine the Performance Rating Since 1198731(1199010) =maxN119895(1199010) = 0999482 119895 = 1 2 3 4 it is shown that theperformance level of ERP project in this enterprise belongsto ldquohighrdquo
45 Sensitivity Analysis Sensitivity analysis is performedaccording to the performance evaluation index systemof ERPproject When the index value or weight of index changesits level variable characteristic value 119895lowast also changes corre-spondinglyWhen the index value changes by 5 10 minus10minus20 minus30 minus40 minus50 respectively the level variablecharacteristic value 119895lowast changes as shown in Figure 2 Whenthe weight of index changes by plusmn10 plusmn20 plusmn30 plusmn40or plusmn50 the level variable characteristic value 119895lowast changescorrespondingly just as the Figure 3
As we can see from Figure 7 the project performanceindexes 1198881 1198882 1198888 11988811 have large effect on the evaluation resultswhich means that the sensitivity of 1198881 1198882 1198888 11988811 is very strongFor example when the 11988811 index changes the range ofthe 119895lowast value varies from 12 to 18 Although ERP projectperformance level does not change the level gradually tendsto ldquogoodrdquo level from ldquohighrdquo level With the change of index1198883 1198884 1198885 1198886 1198887 1198889 11988810 the 119895
lowast value changes a little from 15 to165 It indicates that the variation of index value will notchange the level which the project performance tends to orbelongs to
In Figure 8 we can know that the change of 1198881 and 11988811indexes affects the 119895lowast value obviously but other indexes haveless effect on the 119895lowast value In a word 1198881 and 11988811 are sensitiveindexes in the ERP project performance evaluation
5 Conclusions
ERP system has been introduced into enterprises for manyyears It is necessary to evaluate the performance of theERP project in enterprise However the factors which affectthe performance of ERP project are complex and relatedSo a hybrid evaluation method of ERP project performancewhich considers these peculiarities was proposed In order
Mathematical Problems in Engineering 9
to analyze the performance of ERP project an index sys-tem of comprehensive benefit evaluation including financecustomer and operation management is established in thispaper An ANP was proposed to determine the weight ofeach index which fully took the relationship between variousindicators into account Due to the limitations and inadequa-cies of traditionalmatter-element extensionmodel when per-forming the comprehensive evaluation an improved matter-element extensionmodel was proposed And then taking oneenterprisersquos ERP project as an example the comprehensiveevaluation was done The empirical analysis results show theperformance of ERPproject in our case belongs to ldquohighrdquo leveland our proposed hybrid evaluation model is feasible andpractical Finally a sensitivity analysis is performed to findsensitive index in the ERP project evaluation The analysisresults show that total asset turnover ratio and data transferefficiency are sensitive indexes so this enterprise should paymore attention to them
