Abstract :
Data envelopment analysis is a technique for measuring the
relative efficiency of a set of decision making units with common
data, but in this paper we explain a new method for evaluating of
decision making units with fuzzy data.We solve CCR and BCC
models with fuzzy inputs and outputs by distance minimization that this method
is better than other methods for ranking of fuzzy numbers and
then
we put in order efficient and inefficient decision making units
