Fuzzy DEA models is used to assess decision making units(DMUs) with fuzzy data.However previously proposed fuzzy DEA model may result in more than one efficient DMUs.In order to solve this problem,a fuzzy super-efficiency DEA-AR model is proposed.An algorithm to determine the lower and upper bounds of fuzzy efficiency scores at given α levels is proposed.The proposed model and solution approach are applied to evaluate the performance of banks in the end.
