Abstract :

Technique of Data Envelopment Analysis, involved methods which conducted for desirable objective management of Decision Making unit, that is same increasing of efficiency level. An important topic in DEA interpretation is the ranking of DMUs. There exist many methods for it in crisp DEA. In this paper we use of the new metric DTMF that proposed by T.Allahviranloo and M.Adabitabar for fuzzy ranking of all DMUs.
