There are many issues to be considered in implementing a Shop Floor Control System. Overall Shop Floor Control Systems are seen more readily as a means of helping waste reduction end competitive performance of the business. The practical exercise in this paper surfaced the need for compatibility of software to be used, the need for flexible hardware interfacing and the need for end-user participation in conceptualizing and developing such a system. The purpose of this study is to explain the philosophy and methods utilized by a small company in using computer simulation to enhance the effectiveness and control of its manufacturing operations. An MRP system feeds the master schedule into the scheduling system for detailed shop floor scheduling. This is used for production control, to monitor and to control production operat ions. By simulating Shop Floor Control System, the manufacturing process is much better controlled, modelled and much more understood than previously. Shop Floor Control Systems are seen to offer more than cost reduction and improved production achievement.
