SUMMARY
This research project examines the performance of job shops with different machine layouts and production control systems. Job shops examined in this study operate in a make-to-order environment. Results indicate that the material requirements planning order-release-and-due-date-assignment procedure always performs better than that of the period batch control. Cellular layout, however, performs better at a high setup-to-processing-time ratio, while the process layout performs better at a low setup-to-processing-time ratio
