Research about Suppliers Selection upon Entropy Weight and TOPSIS in the Perspective of Supply Chain

Ke Ning Da, Jing Ru An, Zong Sheng Chen

Abstract

This paper discusses the targets and evaluation standards for suppliers selection, and sets a evaluation mode, combined entropy weight and TOPSIS model. The basic idea of this model is use entropy weight to confirm the weight of each evaluated index, and then ensure the most suitable supplier through TOPSIS model that close to ideal matrix, so as to well avoid the subjectivity assured by low level and multi-factors. The paper introduces this model into detailed practical cases, which aims to state that the combination of entropy weight and TOPSIS model is a very efficient method for suppliers’ selection in supply chain evaluation system.
