چکیده

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 prob-
lem, 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 ex-
ible manufacturing system with little computation, and then we compared the
computational complexity of our proposed method with that of liu''''''''s method.
