The user's role in a simulation based scheduling system

Abstract

This paper focuses on the role of the production scheduler in developing and using a computer simulation based scheduling system. As the scheduling system end user, the production scheduler is responsible for developing schedules which support the business goals of the manufacturing facility. To do so, he must balance many conflicting objectives relating to work-in-process inventory levels, resource utilizations, and customer service. During any single scheduling period, the desired balance may vary with time or across production resources. Simulation based scheduling does not provide an optimum solution, but provides visibility into the effects of decisions. The production scheduler uses this information to perform analyses and to identify opportunities to improve the plan. His participation during system development ensures that the model and reports fully support these activities. While the schedule generation and revision process can be automated, the final analysis of the value of the resulting schedule requires human involvement. A FACTOR scheduling software application is reviewed to illustrate the role of the user in this dynamic environment.
