Abstract
AbstractCompare with the traditional multivariate statistical methods of data processing technology for evaluating problems, TOPSIS method has the characteristics of intuitive analysis principle, simple calculation and less requirement on sample size. Therefore, this paper adopts entropy weight TOPSIS method to establish a comprehensive evaluation model to accurately reflect the gap between suppliers. And extracts the supplier's market share, the stability of supply and demand relationship, supplier reputation as evaluation indexes by mining historical data, establishes a comprehensive evaluation model of supplier's supply capacity, and carries on the quantitative analysis of the supply characteristics. Based on the average supply quantity, transaction times and the probability of supply quantity exceeding or not reaching the enterprise's order quantity in the past five years, the weight of each evaluation index is obtained by using entropy weight method. And the evaluation score that can reflect the importance of production is obtained by MATLAB. Finally, 10 suppliers are identified as the most important suppliers.KeywordsEntropy weight methodTOPSIS methodData processingComprehensive evaluation modelMATLAB
