Abstract
The ELECTRE method utilizes the concordance and discordance set. And then use concordance and discordance indices to construct concordance and discordance matrices. Both concordance and discordance indices have to be calculated for every pair of alternatives. Based on the aggregate matrix, a decision graph can be depicted to determine which alternative is preferable, incomparable or indifferent. It first uses concordance and discordance indices to analyze outranking relations among alternatives from real-world applications. In this paper, an extension of ELECTRE method, a multiple attributes hesitant fuzzy decision making technique, to a decision environment is investigated, where the individual decision value are provided by the hesitant fuzzy information. We first introduce some concepts of hesitant fuzzy set. Then, the hesitant fuzzy ELECTRE method is proposed in detail. Finally, an illustrative example for evaluating the performance of the industry zones is used to illustrate the developed methods.
