Extension Method for Green Supplier Selection

Green supplier selection is a key phase in green supply chain management. The system of evaluation indices for green supplier selection was put forward based on electrical appliance manufacturing enterprise. At the same time, the multi-level extensible synthetic evaluation model 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 evaluation model was applied in green supplier selection in Frestech Co. Ltd. The order preference of suppliers is attained. The best supplier and better suppliers are ascertained for the enterprise. The evaluation process indicates that it is easier to implement this evaluation method in enterprises.
