Multi-criteria decision-making in complex Fermatean fuzzy environment

Abstract

In this article, we present the notion of complex Fermatean fuzzy set. We introduce various operators namely, complex Fermatean Fuzzy weighted average, complex Fermatean Fuzzy weighted geometric operator, complex Fermatean Fuzzy weighted power average and complex Fermatean Fuzzy weighted power geometric operators and discuss some of their properties. Finally, we present a MCDM problem and an algorithm to solve it with supporting case studies using these operators. We have compared the results of these operators to show the reliability of the proposed method.
