Detailed Scheduling Strategy
Definition
A set of settings controlling the
detailed scheduling
of operations and orders in
Production Planning and Detailed Scheduling
.
Use
You use the detailed scheduling strategy to specify which rules and constraints the system uses to determine dates/times and resources for orders and operations, and which scheduling constraints (for example, product and resource availability) it considers when doing this.
Additional operations may be affected by the scheduling or rescheduling of an operation that you have selected specifically for scheduling . In order that the schedule remains consistent, the system must schedule or adjust these operations accordingly. Scheduling or rescheduling of an operation can therefore trigger a chain reaction of detailed scheduling activities for the objects concerned.
Example
You reschedule an urgent operation to another date/time on/at which the resource is already occupied.
If you have specified an insert scheduling mode in the detailed scheduling strategy, the system must move the operations on the resource to create a slot for this operation (scheduling mode insert operation ), and to close the newly created gaps (scheduling mode inserting an operation and closing gaps ).
If you have specified in the detailed scheduling strategy that the system must retain time relationships or pegging relationships to the dependent operations when rescheduling the operations and the neighboring operations, the system must then reschedule the dependent operations so that these relationships are not violated.
Structure
You can use strategy settings to control both the scheduling of the selected operations, and the subsequent rescheduling of the affected operations. You can divide the strategy settings into the following groups accordingly:
