A Straightforward Advanced Ranking Approach of Fuzzy Numbers

Abstract

Fuzzy set is commonly explored to deal with uncertainty generally involved in decision-making process. Moreover, ranking of fuzzy numbers plays efficient role in the process in order to adopt appropriate action by a decision-maker in any real-world problems under uncertain environment. A few numbers of ranking approaches have been encountered in last few decades. However, it is observed that the existing approaches are more often situation dependent and have lots of drawbacks. In this regard, this paper presents a straightforward general approach based on the concept of the exponential area of the input fuzzy numbers. The outputs produced by this present approach are more efficient in comparison to the other ranking approaches and successfully work in all situations. The efficiency of the approach has been showcased by comparing with existing recent approaches. Furthermore, the ranking approach has been successfully applied in medical investigation problem and observed that the results obtained by the approach corroborate the analytical result and human intuition as well.
