Process for Capacity Requirements Planning in Plant Maintenance

Purpose

In Plant Maintenance, you use capacity requirements planning if you want to maximize the capacity of the individual work centers for work scheduling, in view of the changing daily requirements.

Required Knowledge

If you want to use capacity requirements planning for Plant Maintenance effectively in your company, you need knowledge of the following areas:

Work center in Plant Maintenance

Refer to Work Center (PM and CS) and The Work Center (PP/General).

Planning elements in Plant Maintenance:

Notifications

Orders

Task lists

Maintenance plans

Knowledge of personnel administration (application component PA-PA) and time management.

Customizing

To optimize your use of capacity leveling, you must make certain settings in the Customizing for Plant Maintenance. The settings are usually made by your system administration.

For more information, see Settings and Profiles for Capacity Leveling.

Process Flow

Capacity requirements arise in Plant Maintenance from tasks that are requested in the form of orders. The capacity requirements requested and scheduled match the limited available capacity of the work centers and individual persons.

The maintenance planner has the following options:

The planner enters the required work center in the order operation, schedules and saves the order. The system provisionally plans the requested capacity requirement to the work center. This means that initially the work is planned, but "not binding" for this work center.
The planner enters a person in the operation for the order. This means that initially the work is planned, but "not binding" for this person.

For more information, see Selection of a Suitable Person.

If the planning has been completed as far as possible, the planner can check the capacity availability, which they have entered for the operations. The capacity requirement for other orders or other operations is considered for this work center.

For more information, see Capacity Availability Check.

Owing to the number of orders resulting from both unplanned maintenance and preventive maintenance, it is often not possible to utilize all of the available work centers and persons equally when the order is created. Usually, some will have less capacity than is planned, whilst others will have more.

To utilize resources fully, the maintenance planner must regularly perform capacity leveling. To do this, the planner selects the graphical or tabular planning board, and then uses the functions available for capacity leveling.
