APS systems are designed to support planners and make their jobs easier, not replace them. Instead of wasting time and energy on tedious scheduling tasks, planners can generate schedules in a few seconds. Therefore, their expertise can be utilized in optimizing schedules by comparing multiple versions generated with different assumptions and optimization rules. It’s crucial to remember that an APS system is a tool, and its effectiveness depends on human input. If necessary, planners can reassign resources, sequences and priorities, to achieve a perfect balance between automation and expert control.
