An integrated decision support system for FMS: Using intelligent simulation

In the present study, an integrated decision support system is presented for a manufacturing system, considering a three-level interdependent planning hierarchy. Decision making processes are identified for all the management planning levels. Master production schedule, bill of materials, and inventory records generate the material requirement plan, and in turn the schedule of arrival of the parts in the shop. The DSS so designed is capable of supporting various kinds of decisions at all levels using simulation as the main technique. A generic simulation model is developed for the flexible manufacturing systems. Simulation is designed to be an intelligent simulation system for proper integration.
