A METHOD FOR RANKING DECISIONAL ALTERNATIVES USING INTUITIONISTIC FUZZY SETS

Abstract

This paper proposes a new method for ranking the alternatives represented under the form of IFS. The method is analysed in comparison with other techniques used for ordering introduced by Xu (2007), Szmidt and Kacprzyk (2008). The order is determined based on the distance to the ideal solution (the optimal point) and on the distance to the points Ppes and Pned corresponding to the maximum level of non-membership, and of indeterminacy, respectively. The proposed method is applied in a multi-attribute decision model.
