The sensible selection of celestial objects for observation by the James Web Space
Telescope (JWST) is pivotal for the precise decision-making (DM) process, aligning with …

–spherical fuzzy sets are an extension of picture fuzzy, spherical fuzzy and t-spherical fuzzy
sets, which allow for a more flexible representation of uncertainty. In a–spherical fuzzy set …

Complex spherical fuzzy set, an extended version of spherical fuzzy set, is a very powerful
tool to capture fourfold information (typically yes, no, abstain and refusal), in which the range …

The multi-criteria decision-making (MCDM) tool is a robust decision-making technique
utilized in several fields like networking, risk management, digital analysis, cybercrime …

This study focuses on the development and application of Aczel–Alsina (AA) aggregation
operators (AOs) in the context of r, s, t-spherical fuzzy set (SPFS) for multi-criteria decision …

T-spherical fuzzy set is a recently developed model that copes with imprecise and uncertain
events of real-life with the help of four functions having no restrictions. This article's aim is to …

Traditional fuzzy decision-making methods still have certain limitations in practical
applications, such as the problem of the sum of attribute memberships and non …

Keeping in view the significance of spherical fuzzy set (SFS), this research focuses on
innovative multi-criteria group decision-making (MCGDM) technique for coping with …

A complex spherical fuzzy set (CSFS), an extension of a spherical fuzzy set, is a worthwhile
notion in which the range of degrees occurs in the complex plane within unit disk. A CSFS …

In this study, we first introduced the spherical fuzzy Z-numbers (SFZNs) and developed
some basic operational rules. SFZNs can be used effectively to make true ambiguous …
