Study on Supplier Selection of Manufacturing in Lean Closed-Loop Supply Chain

In lean closed-loop supply chain, suppliers are required to make a rapid response for the changing market, at the same time, the capability of resource recycling is also important. So supplier selection is critical for manufacturing enterprises based on lean closed-loop supply chain. This paper builds a manufacturing supplier evaluation model in lean closed-loop supply chain. Weight is given to indicator by entropy-weighing method, and it makes the comprehensive evaluation and sorting for supplier using the gray relational analysis method, and a new decision program is presented. Finally an example was shown and validation was proved in selection of suppliers. According to the variation of individual indicators, calculate the criteria weighting coefficients by quoting from the information entropy to reflect the utility value of the data itself. It can avoid the formation of redistribution deviation which is affected easily by personal subjective factor.
