Application of variational iteration method for solving singular two point boundary value problem

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''''''''[۱۱]. 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.
