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 …

The generalized Heronian mean and geometric Heronian mean operators provide two
aggregation operators that consider the interdependent phenomena among the aggregated …

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 …

A useful expansion of the intuitionistic fuzzy set (IFS) for dealing with ambiguities in
