چکیده
|
Data envelopment analysis is a technique for measur-ing the relative e±ciency of a set of decision making units withcrisp data, but in this paper we explain a new method for evalu-ating of decision making units with fuzzy data.at ¯rst, we introduce fuzzy data envelopment analysis models withparameters as trapezoidal membership function. then we
