A multicriteria group decision making approach for evaluating renewable power generation sources

This paper formulates the renewable power generation sources’ performance evaluation problem as a multicriteria group decision making problem, and presents a new multicriteria group decision making approach for effectively evaluating the performance of renewable power generation sources. The subjectiveness and imprecision of the decision making process is adequately handled by using intuitionistic fuzzy numbers. A multicriteria group decision making approach based on the TOPSIS approach and the degree of similarities are introduced for obtain-ing the relative degree of closeness value of each alternative on which the final decision can be made. An example is presented for demonstrating the applicability of the approach for dealing with renewable power generation sources’ performance evaluation problem.
