Optimization of Deallocation Costs 

Use

You can use the optimization to optimize planning by reducing the sum of the deallocation costs. Deallocation costs arise due to the deallocation of activities. The optimization assigns deallocation costs to a deallocated activity. These costs correspond to the shortest net duration of the modes of an activity.

To reduce the deallocation costs for an activity, the system can try to schedule the activity without a delay, during optimization. Optimization attempts to minimize the number of deallocated activities.

You cannot weight deallocation costs in the optimization profile. Optimization calculates the weight internally so that a deallocated operation always causes higher costs than a scheduled one. The result of the weighted total of the deallocation costs is:

Weighted total of the deallocation costs =
Weighting x Total of the deallocation costs x 1 second

Prerequisites

In the optimization profile, or when you called optimization, you have selected the options Deallocate if to the right of optimization horizon, Deallocate delayed operations or Deallocate delayed operations with successor operations on the Basic Settings tab page.
