Defuzzification Method for Ranking Fuzzy Numbers Through Radius of Gyration

Abstract

The present paper aimed at designing a new method to rank fuzzy numbers by distance method. The purpose of the present study was to introduce a new method in order to value various fuzzy numbers effectively and at the same time to overcome the shortcomings of the previous studies. To fulfill the purpose of the study the proposed method was based on the radius of gyration point of ROG points and used the semi variance value of fuzzy numbers as benchmark. Finally, the findings are discussed as far as comparative examples are concerned to be useful to illustrate the advantage of the proposed method.
