Electre Method Using Interval-Valued Intuitionistic Fuzzy Sets And Possibility Theory For Multi-Criteria Decision Making Problem Resolution

In this work we propose an approach of multicriteria decision making (MCDM) using Elimination Et Choice Transiting Reality (ELECTRE) methods, interval-valued intuitionistic fuzzy (IVIF) sets and possibility theory. The proposition concerns the computation of concordance sets and discordance sets using possibility measures. The proposed approach is applied to select the best investment projects decision problem from literature. Therefore results are compared and concluding remarks are given.
