American aerospace manufacturing operations are evaluating and implementing numerous Flexible Manufacturing Systems. Each application is a complex combination of various support systems found in a more traditional production environment. Predicting how these systems will work within the integrated framework of an FMS can be very complicated. Simulation is a valuable tool for not only evaluating a complex system for feasibility, but it can also be incorporated as a design aid. The following paper describes how a simulation model was used to assist in the design and planning of an FMS.A SLAM discrete event simulation model provided many insights into proposed system behavior and how it affected performance. In addition, this model functioned as a design tool during system development. Model development centered around a group participation concept. The model provided statistics for machine tool utilizations, manual station utilizations, inventory levels, product lead times, production levels, and queueing requirements.This particular FMS was dedicated to the machining of a complex product requiring special material handling and quality considerations often associated with high tolerance machining processes. Several simulation runs were dedicated to machine capacity and material handling capabilities. The system design process utilized much of the information obtained via modeling.
