7 Arithmetic operations on generalized semielliptic intuitionistic fuzzy numbers and their application in multicriteria decision making

Abstract

This chapter attempts to initiate a novel generalized semielliptic intuitionistic fuzzy number (GSEIFN) along with basic arithmetic operations on GSEIFNs. Furthermore, an advanced ranking method for GSEIFN is proposed. In the end, a multicriteria decision-making problem has been carried out by using the proposed GSEIFN and the ranking approach to exhibit the legality and applicability.
