Supplier Selection using Fuzzy Relations: A Multi-Criteria Decision-Making Approach

Abstract

This paper presents an advanced fuzzy relation-based methodology for supplier selection. By incorporating Quality (Q), Delivery (D), and Cost (C) as key criteria, a fuzzy relation matrix is developed to evaluate supplier performance. The final selection is made using a weighted ranking approach. The proposed methodology ensures a balanced and objective decision-making process, accounting for uncertainty and expert judgment. Additional aspects such as risk management and sustainability are also considered for a comprehensive evaluation.
