An approach for ranking discrete fuzzy sets

Abstract

In this paper we present a new method for ranking discrete fuzzy sets. Comparing between two or more fuzzy numbers and ranking them is an important subject in fuzzy theory. Our method is a simple and effective parametric method to compare fuzzy numbers and discrete fuzzy sets. The proposed method can be utilized for all types of fuzzy sets whether normal or abnormal. In the end we present an example to illustrate the method.
