The planning strategy settings in the Capacity Scheduling Table determine how the system schedules the operations or orders on the resources. You can select the following settings:
Finiteness level: This setting defines how strictly the system considers the capacity availability of the resources when scheduling. You can choose between infinite, finite, and optimized scheduling. Infinite scheduling ignores the capacity availability and schedules the operations or orders as early as possible. Finite scheduling respects the capacity availability and schedules the operations or orders only in the free slots of the resources. Optimized scheduling tries to find the best compromise between infinite and finite scheduling by minimizing the delays and overloads12 Scheduling control: This setting defines how the system handles the scheduling conflicts that may arise when scheduling the operations or orders. You can choose between rescheduling, shifting, and splitting. Rescheduling means that the system moves the conflicting operations or orders to a later date. Shifting means that the system moves the conflicting operations or orders to another resource within the same resource network. Splitting means that the system splits the conflicting operations or orders into smaller parts and schedules them on different resources or dates13 Direction: This setting defines the direction of the scheduling. You can choose between forward and backward scheduling. Forward scheduling means that the system schedules the operations or orders from the start date to the end date. Backward scheduling means that the system schedules the operations or orders from the end date to the start date14 Reference:
