Abstract

This paper discusses a multi-criteria decision making model on intuitionistic fuzzy sets. Based on the similarity measure between intuitionistic fuzzy sets, a novel method is shown for the multi-criteria decision making model, the starting point of the proposed method is a geometrical interpretation of intuitionistic fuzzy set. An alternative is mapped to an intuitionistic fuzzy value by using the degree of similarity, and then a score function is used to measure the degree of suitability that an alternative satisfies the decision maker's requirement. Examples are given to show the proposed method's effectiveness.
