Decision Aid Algorithm for Kidney Transplants Under Disc Spherical Fuzzy Sets With Distinctive Radii Information

Abstract

The Circular Spherical Fuzzy Set (C-SFS) and Disc Spherical Fuzzy Set (D-SFS), an innovation of the well-known Spherical Fuzzy Set, are introduced in this research study. It is intended to improve the representation and processing of uncertainty in decision-making scenarios. The study establishes the C-SFS's basic relations and operations, giving it a solid foundation for use in a variety of fields. An ELECTRE method utilising the C-SFS framework is suggested to properly quantify the decision-making process. This methodology combines circular spherical fuzzy concordant and discordant matrices, making it easier to evaluate performance thoroughly in terms of many different factors. The orderly structure of this strategy is demonstrated by a structured flow chart. Real-world applications of the C-SFS ELECTRE approach, particularly in the critical setting of kidney transplant selection, serve to demonstrate its effectiveness. A comparative section is included to demonstrate the suggested method's accuracy.
