The ELECTRE methods have been applied to solve MCDM problems in a wide variety of fields. But to the best of our knowledge there is no considerable attempt to fuzzify the ELECTRE method in an effective and easy to use manner. Therefore the aim of this paper is to propose an extension to ELECTRE method for incorporating fuzzy data into the decision-making process. In this paper we consider triangular fuzzy numbers to account for the vagueness and impreciseness of decision-maker(s) (DM) judgments
