As an improved form of fuzzy sets (FSs), spherical fuzzy sets (SFSs) could provide decision
makers (DMs) with more free space to express their preference information. In this article, we …

As a new improvement of fuzzy sets (FSs), spherical fuzzy sets (SFSs) can provide a wider
space for decision-makers (DMs) to express their preference information. Spherical fuzzy …

T-spherical fuzzy set (T-SPFS) is a generalization of several fuzzy concepts such as fuzzy
set (FS), intuitionistic FS, picture FS, Pythagorean FS, and q-rung orthopair FS. T-SPFS is a …

Spherical fuzzy sets (SFSs), recently proposed by Ashraf, is one of the most important
concept to describe the fuzzy information in the process of decision making. In SFSs the sum …

The paper aims to present the concept of power aggregation operators for the T-spherical
fuzzy sets (T-SFSs). T-SFS is a powerful concept, with four membership functions denoting …

The recently proposed partitioned Bonferroni mean (PBM) can effectively deal with
situations in which attributes are partitioned into several parts, and attributes in the same …

In this article, to synthesize the merits of interaction operational laws (IOLs), rough numbers
(RNs), power average (PA) and Heronian mean (HM), a new notion of T-spherical fuzzy …

Spherical fuzzy sets are an extension of various fuzzy concepts and demonstrate fuzzy
opinion using membership, abstinence, nonmembership and refusal degrees with relaxed …

Spherical fuzzy sets (SFSs) provide more free space for decision makers (DMs) to express
preference information from four aspects: approval, objection, abstention and refusal. The …

The spherical fuzzy set (SFS) is one of the most important concepts to accommodate more
uncertainties than the intuitionistic fuzzy set, Pythagorean fuzzy set, picture fuzzy set and …
