TOPSIS METHOD FOR GREEN VENDOR SELECTION IN COAL INDUSTRY GROUP
Green vendor selection is a key phase in green supply chain management The system of evaluation indices for vendor selection was put forward based on coal industry group corporation Ltd. At the same time, the multi-level model of TOPSIS(Technique for Order Preference by Similarity to Ideal Solution), which is based on entropy weight, was constructed. The subjectivity which lies in ascertaining factors weights in lower hierarchy was avoided in this model. So the evaluation result is more objective than other evaluation methods. The improved decision model was applied in vendor selection in Ping Dingshan coal industry group. The order preference of vendors is attained. The excellent vendor and perfect vendors are ascertained for the enterprise. Whats more, the difference among these vendors can be gained as well. The evaluation result indicates that this method be more reasonable and easier to grasp than other methods. As a result, it is easier to popularize this evaluation method in enterprises.
