Analyzing Scheduling and Calculation of Capacity Requirements

The figure, Lead Time Scheduling, describes which time elements are included in lead time scheduling of a planned order or production order.

The durations for the setup, processing, and teardown of an operation are calculated on the basis of the scheduling formulas of the assigned work center. A separate formula is defined for each of the three time elements. 

Since several different capacity categories with different available capacities can be assigned in a work center, a capacity category must be defined as the scheduling basis. Furthermore, work center-specific formula constants can be defined in order to be able to take into account special properties of a work center, such as a flow rate.  

A formula can include the standard values, the operation quantity, the base quantity, the workplace-specific formula constant and, if required, further parameters. The control key of the operation must allow scheduling.

The capacity requirements for the setup, processing, and teardown of an operation are calculated per capacity category on the basis of the capacity formulas of the assigned work center. The calculation of capacity requirements follows a similar approach as the calculation of the durations.
