Manufacturing planning & control (MPC)

systems are the systems that deals with all

the activities from acquisition of raw

material to the delivery of completed

product.

FRONT END

The front end, is the set of activities and systems for overall

direction setting. This phase establishes the overall company

direction for manufacturing planning and control.

ENGINE

The middle third, or engine, encompasses the set of MPC

systems for detailed material and capacity planning.

BACK END

The bottom third, or back end, depicts MPC execution systems.


6/15

Demand planning encompasses forecastingcustomer/end-product demand, order entry,

order promising, accommodating interplant andintercompany demand, and spare partsrequirements.

Production planning is the activity whichprovides the production input to the companygame plan and determines the manufacturingrole in strategic plan.


7/15

The Master Production Schedule (MPS) is the

disaggregated version of the sales and operations

plan. That is, it states which end items or product

options manufacturing will build in the future.

The master production schedule feeds directly

into the detailed material planning module.


8/15

Material Requirement and Planning (MRP) determines

the period-by-period plans for all component parts and rawmaterials required to produce all the products in the MPS.

This technique determines what component are needed

and when they should be ordered so that they are likely tobe available as needed.

This material plan can thereafter be utilized in the

detailed capacity planning systems to compute labor ormachine center capacity required to manufacture all thecomponent parts.

In the back end the system configuration

depends on the products manufactured andproduction processes employed.

Their shop floor system establishes prioritiesfor all shop orders at each work center so the

orders can be properly scheduled.

Purchasing system provide detailed planning

information for vendor scheduling.

These 5 levels of capacity planning activitiesrange from large aggregation of capacities forlong term period to very detailed machinescheduling for shorter time interval.

There must be a correspondence between thecapacity required to execute a given materialplan and that made available to execute a plan.If the correspondence does not exist the planeither be impossible to execute.


12/15

Resource planning activity is directly linked to

production planning module. Resource

planning involves converting monthly quarterlyor even annual data from production plan into

aggregate resources such as goods labor hours ,

floor space , machine hours and links.


13/15

The master production schedule is the primary

source for rough cut planning.

The capacity requirements of particular masterschedule can be estimated by techniques like

I. Capacity planning using overall planning factor

(CPOF)

II. Capacity bills

III. Resources profile


14/15

The material plans produced by MRP systems

serve as the basis for calculating time-phasedcapacity requirements.

The finite loading is a method for schedulingwork orders.

The input and output analysis helps inmonitoring the actual consumption of capacity

during the execution of material plans.
