Abstract

Data envelopment analysis is a technique for measuring the relative e±ciency of a set of decision making units with crisp data, but in this paper we explain a new method for evaluating of decision making units with fuzzy data. At ¯rst, we introduce fuzzy data envelopment analysis models with parameters as trapezoidal membership function. Then we extend this method for solving models with general parameters.
