Simulation of a flexible manufacturing system

In this report we describe the program organization, input data preparation, and output data intepretation for FMSIM, a manufacturing system and scheduling policy simulation tool. FMSIM is a FORTRAN 77 program package that is organized on a modular basis, with separation between scheduling policies and the simulation of an automated production system. This important feature enables schedulers to compare the performance of different policies for the same physical system. We describe the detailed implementation of Kimemia and Gershwin's hierarchical scheduling policy, as enhanced by Gershwin, Akella, and Choong. We also describe the simulation model and implementation of the IBM Miniline at Tucson.
