THE GROUP FUZZY ELECTRE METHOD TO EVALUATE THE QUALITY OF PUBLIC TRANSPORTATION SERVICE

Abstract

Today, many of the problems in decision making are done as multi-attribute by some qualified persons. In this paper, a method is proposed in which multiple attribute decision-making is done based on the ELECTRE method in fuzzy environment. Using this method makes it possible to determine the indexes' value based on subjective judgments of decision makers in the form of linguistic variables, and then indicators' values and indexes' weights should be used for ranking options. In this method, the possibility to compare indexes has been provided by using Yager ranking index. Also, in the case study, public transportation systems were ranked based on the determined indexes and applying the suggestive method.
