Implementing a simulation-based scheduling system for a two-plant operation

Scheduling any complicated job shop becomes increasingly more difficult when the cycle time is reduced. We discuss the implementation of a simulation-based scheduling system that properly schedules parts in a two-plant operation. The system has allowed the company to reduce the cycle time by at least a week from two/three weeks to one/two weeks. As part of the project, the generation of the input data needed to drive the simulation is also discussed since this data did not exist in the correct form. The model generation, simulation development, and experimentation will be discussed. The system that is described is currently being used to generate the schedules.
