This research presents the Performance Evaluation of Flexible Manufacturing System (FMS) in the manufacturing system. The performance of FMS has been optimized using the developed methodology that includes the flexibilities in manufacturing. Flexible Manufacturing System (FMS) is a capital-investment intensive and complex system. In the present market scenario, the customer demand and specification of any product changes very rapidly so it is very important for a
manufacturing system to accommodate these changes as quickly as possible to be able to compete in the market. This evolution induces often a conflict for a manufacturing system because as the variety is increased the productivity
decreases, hence FMS is a good combination between variety and productivity.
