Abstract

A key objective of procurement is to purchase the right product from right supplier at right price in due time. In this paper, we are going to propose a fuzzy method for the evaluation of suppliers under fuzzy environment. First we identify the strength and weakness of suppliers from their ratings. Based on the strength and weakness of suppliers, a fuzzy preference relation is constructed. Then we propose a linear programming model to derive the priorities of suppliers.
