Data mining is a thoroughly advanced method that evaluates and makes more sense of a
variety in electronic commerce (e-commerce)-related knowledge, discovering useful ideas …

The q-rung orthopair fuzzy sets (q-ROFSs), originally proposed by Yager, can express
uncertain data to give decision-makers more space. The q-ROFS is a useful tool for …

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 …

In this paper, the novel approach of complex T-spherical fuzzy sets (CTSFSs) and their
operational laws are explored and also verified with the help of examples. CTSFS composes …

In this manuscript, the technique of the generalized MULTIMOORA method is investigated
by using the concept of a T‐spherical fuzzy set (T‐SFS), which is the modified idea of a …

The operations proposed by Dombi based on t-norn (TN) and t-corom (TCN) are generally
known as Dombi operations, which offer versatility in the working behavior of parameters …

In this paper, we investigate the multi-criteria group decision-making (MCGDM) problems
with incomplete weight information under T-spherical fuzzy environment. Firstly, motivated …

This paper aims to amalgamate the notion of a T-spherical fuzzy set (T-SFS) and a linear
Diophantine fuzzy set (LDFS) to elaborate on the notion of the T-spherical linear …

In recent years, fossil fuel resources have become increasingly rare and caused a variety of
problems, with a global impact on economy, society and environment. To tackle this …

Complex T-spherical fuzzy 2-tuple linguistic set (CTSF2-TLS), which is a combination of
complex fuzzy set (CFS), T-spherical fuzzy set (TSFS), and 2-tulpe linguistic variable set (2 …
