Aggregation Operators Applied to Cotangent Trigonometric Spherical Fuzzy Sets and its Generalization

Abstract

This paper presents a new method to generate cotangent trigonometric (α, β) spherical fuzzy sets (SFS). The SFS and (α, β) SFS are extended by this. This article will lead to a discussion of the concepts of of COTT spherical fuzzy weighted averaging (SFWA), COTT spherical fuzzy weighted geometric (SFWG), generalized COTT spherical fuzzy weighted averaging (GCOTTSFWA) and generalized COTT spherical fuzzy weighted geometric (GCOTTSFWG). Furthermore, idempotency, boundedness, commutativity, and monotonicity characterize the COTTSFN method.
