Nowadays, manufacturing firms require to meet demand, increase quality and decrease cost due to continuous changes in the market. Because of the importance of flexible manufacturing system (FMS), the optimum operator allocation problem in Cellular Manufacturing Systems (CMS) is a challenging issue. Hence, this paper presents a decision making approach based on Fuzzy Analytical hierarchy process (Fuzzy AHP), technique for Order Performance by Similarity to Ideal Solution (TOPSIS) and computer Simulation to determine the most efficient number of operators and the efficient measurement of operator assignment in Cellular Manufacturing Systems (CMS).
