In today’s world, decision-makers face a complex and uncertain problem due to various attributes, such as the indefinite mind of an individual and uncertain information. A fuzzy set developed a suitable method to deal with inaccurate perspectives. The paper aims to develop a novel fuzzy extended set, the Quad fuzzy set used as a powerful tool compared to the Pythagorean fuzzy set (PFS) and Fermatean fuzzy set (FFS). We introduce the arithmetic and geometric operators for the Quad Fuzzy Set. Further, a case study problem is demonstrated using Analytic Hierarchy Process (AHP), a Decision-Making Method. Moreover, the study compares the best crop variety of sugarcane grown in Tamil Nadu. Finally, a clarified numerical model of selecting a best choice in crop variety of sugarcane is demonstrated with its practicability and effectiveness.
