Abstract :

DEA methodology allows DMUs to select the weights freely, so in the optimalsolution we may see many zeros in the optimal weight. to overcome this prob-lem, there are some methods, but they are not suitable for evaluating DMUswith fuzzy data. In this paper, we propose a new method for solving fuzzyDEA models with restricted multipliers with less computation, and comparethis method with Liu''''''''[11]. Finally, by the proposed method, we evaluate a ex-ible manufacturing system with little computation, and then we compared thecomputational complexity of our proposed method with that of liu''''''''s method.
