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 …

In many real-life decision making (DM) situations, the available information is vague or
imprecise. To adequately solve decision problems with vague or imprecise information …

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 power Bonferroni mean (PBM) operator can relieve the influence of unreasonable
aggregation values and also capture the interrelationship among the input arguments, which …

Spherical fuzzy sets (SFSs) are a new extension of Cuong's picture fuzzy sets (PFSs). In
SFSs, membership degrees satisfy the condition instead of as is in PFSs. In the present …

The q‐rung orthopair sets (q‐ROFSs) is an extended version of conventional orthopair fuzzy
sets, such as intuitionistic fuzzy sets (IFSs) and Pythagorean fuzzy sets (PFSs). The most …

The linear Diophantine fuzzy set (LDFS) has been proved to be an efficient tool in
expressing decision maker (DM) evaluation values in multicriteria decision‐making (MCDM) …

Keeping in view the importance of new defined and well growing spherical fuzzy sets, in this
study, we proposed a novel method to handle the spherical fuzzy multi-criteria group …

In this paper, we propose a new entropy measure of Pythagorean fuzzy sets (PFSs). The
proposed entropy measure of PFSs can conquer the shortcomings of the existing entropy …

Keeping in mind the importance and well growing Pythagorean fuzzy sets, in this paper,
some novel operators for Pythagorean fuzzy sets and their properties are demonstrated. In …
