Abstract :
DEA methodology allows DMUs to select the weights freely, so in the optimal solution we may see many zeros in the optimal weight. to overcome this problem, there are some methods, but they are not suitable for evaluating DMUs with fuzzy data. In this paper, we propose a new method for solving fuzzy DEA models with restricted multipliers with less computation, and compare this method with Liu’[11]. Finally, by the proposed method, we evaluate a flexible manufacturing system with little computation, and then we compared the computational complexity of our proposed method with that of liu’s method.
