Compact Scheduling for Deallocated Operations

The following graphic explains, in the form of an example, how the system executes compact scheduling for deallocated orders . During the compact scheduling of deallocated operations, the system compactly schedules the deallocated operations from all the orders affected by the rescheduling of an operation.

Compact Scheduling for Deallocated Operations

Orders A, B and C each contain the scheduled operations 10, 20 and the deallocated operation 30. The end-start relationships between operations 10 and 20, and between operations 20 and 30 are defined with a minimum interval of 0.

When you reschedule the scheduled operation A10, the system tries to shift the deallocated operation A30 as close as possible to operation A20, taking into account the minimum interval (even when A20 was not shifted and the relationship to A30 was not violated).

As a result of rescheduling A10, the scheduled operation B10 from order B is affected, for example, because the planning mode Insert operation is set, and B10 therefore has to be shifted. The system now tries to shift the deallocated operation B30 in such a way that the minimum interval to B20 is achieved (even when the relationship was not violated).

Order C is not affected by rescheduling operation A10. Therefore, the deallocated operation C30 is not scheduled compactly; that is, it is not shifted towards operation C20.
