Available Capacity

You can store the operating time and the daily available capacity at a work center in a capacity in the work center. You identify a capacity at the work center using the capacity category. Various capacity categories can be assigned to the work center, for example, a machine capacity or a labor capacity, but each capacity category can only be assigned once.

You can maintain the available capacity of a capacity at the work center or in a capacity that is independent of any work center.

For every capacity in the work center, you can maintain a standard available capacity and several versions of available capacity . The standard available capacity has unrestricted temporal validity.

You can specify available capacities that change over time in the versions of available capacity. You can use any units of measure and intervals of available capacity

The available capacity (see figure below) is determined by:

Work start and work finish
Length of breaks
Rate of capacity utilization
Number of individual capacities which the capacity consists of

You can simplify the maintenance of available capacities by using

shift definitions and shift sequences .

To define the available capacity, you must maintain the following data in the capacity header:

The grouping, that defines which shift sequences and shift definitions can be used to maintain the available capacity
The number of the active version of available capacity
The base unit of measure of the available capacity
The factory calendar, that is the basis of the available capacity

If you do not enter a factory calendar, the system uses the default calendar for the plant.

You can find a more detailed description of the maintenance of capacity categories and available capacities in the documentation PP - Work centers.

Which Available Capacity is used in Capacity Planning?

In Customizing for Capacity planning, you can specify which version of available capacity should be used for the capacities at the work center. You can make this specification:

in the selection profile for capacity evaluation
in the selection profile for capacity leveling

If you do not specify a version of available capacity in these profiles, the version of available capacity is used that is specified as active in the capacity header. If none of the versions of available capacity is marked as active, the system uses the standard available capacity.

Cumulating Available Capacities

You can cumulate available capacities to a hierarchy work center using work center hierarchies.

To do this, read Cumulating Available Capacities and Capacity Requirements
