A fuzzy multiple criteria decision making approach based on value points of fuzzy numbers

In this paper, the value point of a number is defined and its comparative properties are found with the centroid point.Then, based on the value point of fuzzy numbers and complex numbers arithmetic, a fuzzy multiple criteria decision making approach for ranking of alternatives is proposed. The proposed approach provides an effective and appropriate way for the decision makers. A numerical example is examined to illustrate the results of applying the method.
