Available Capacities

Daily Basis or Shift Basis

The available capacity of a capacity category in a work center on a daily or a shift basis is defined in the R/3 system as the product of the number of individual capacities and the productive working time.

The productive working time is called the operating time and is derived from the following data:

Work start and work finish determine the working time. This data is also important for scheduling operations, since an operation can only be carried out during working time. If the break times are subtracted from the working time you obtain the theoretically productive working time.

The capacity utilization rate takes unplanned interruptions, such as technical faults or organizational disturbances, into account. It tells you how many percent of the theoretically available working time is used productively.

From this data you can calculate the operating time:

Operating time = (Working time - Break time) x Capacity utilization rate/100%

 

The following graphic shows schematically the relationships described above.

Description of Available Capacity

The smallest units of available capacity are either days or shifts. The available capacities for a longer period are built up of these units and are stored in standard available capacities or intervals of available capacity.

The available capacity is maintained in a base unit with the dimension "time". It uses the factory calendar.

Alternative Available Capacity in Work Centers

You can enter several available capacity versions for each capacity category. These are identified by version numbers.

Different Capacity Categories in a Work Center

The available capacity is defined for every capacity category in a work center. You can reference or copy an available capacity from another capacity category.

Cumulation of Available Capacities via Hierarchies

You can cumulate available capacities from subordinate work centers to a work center superior in the hierarchy. The cumulation of available capacity is important for capacity planning.
