Optimization Range
Range for which the system optimizes the schedule during optimization. The optimization range is defined by the following:
· The optimization horizon
· The resources that are transferred to the optimization
During optimization, the system can only change the schedule within the optimization range; that is, it can only reschedule activities that:
· Lie entirely within the optimization horizon
· Are exclusively at resources that are transferred to the optimization
In particular, the
system can only reschedule an activity to
alternative
resources during optimization if these resources are included in the
resource selection for the optimization.
During optimization, the system cannot change activities that are outside of the optimization range. Relationships between activities within and outside the optimization range are therefore hard constraints for the optimization.

Additional activities within the optimization horizon can be fixed for the optimization.

To improve performance when you are dealing with larger scheduling problems, you can use decomposition to divide up the optimization range into several smaller problems.
