BIPOLAR PYTHAGOREAN FUZZY NEUTROSOPHIC SET (BPNS) INTEGRATED WITH AHP EXPRESS (BPNS-AHP EXPRESS) WITH LINGUISTIC VARIABLE: A NEW APPROACH

Abstract

Decision-making in real-world situations inherently involves uncertainty and insufficient information. To overcome these challenges, decision-makers must adopt techniques that recognize and mitigate the influence of unknown or insufficiently known elements in the decision environment. A single technique often does not address these diverse scenarios, as multiple perspectives may emerge. AHP-express, a simplified form of the Analytic Hierarchy Process (AHP), has recently been introduced; however, the development of a new linguistic variable for AHP-express has not been thoroughly investigated. This study initiates the integration of the newly generalized fuzzy set, known as Bipolar Pythagorean Neutrosophic Set (BPNS), with AHP-express (BPNS-AHP express). We develop linguistic variables within the BPNS-AHP express framework using a 7-point linguistic scale, ensuring that BPNS-outlined requirements are met. This articles highlights the six step BPNS-AHP express procedure and demonstrates how it can enhance decision-makers effectiveness across various application domains by providing a more thorough and accurate representation of their thoughts and judgments.
