Pythagorean fuzzy set, generalized by Yager, is a new tool to deal with vagueness
considering the membership grade μ μ and non-membership ν ν satisfying the condition μ …

Abstract The fuzzy DEMATEL (Decision Making Trial and Evaluation Laboratory) method is

In this paper, we propose Fermatean fuzzy sets. We compare Fermatean fuzzy sets with
Pythagorean fuzzy sets and intuitionistic fuzzy sets. We focus on complement operator of …

All the extensions of ordinary fuzzy sets with three dimensional membership functions such
as intuitionistic fuzzy sets (IFS), intuitionistic fuzzy sets of second type (IFS2), and …

The q‐rung orthopair fuzzy sets (q‐ROFs) are an important way to express uncertain
information, and they are superior to the intuitionistic fuzzy sets and the Pythagorean fuzzy …

Fermatean fuzzy sets (FFSs), proposed by Senapati and Yager (0000), can handle uncertain
information more easily in the process of decision making. They defined basic operations …

A useful expansion of the intuitionistic fuzzy set (IFS) for dealing with ambiguities in
information is the Pythagorean fuzzy set (PFS), which is one of the most frequently used …

The 5G industry is of great concern to countries to formulate a major national strategy for 5G
planning, promote industrial upgrading, and accelerate their economic and technological …

The generalized Heronian mean and geometric Heronian mean operators provide two
