Abstract: Limnetic products supplier selection is a multi-criteria decision problem which involves many factors. In order to choose the optimal supplier, it is necessary to weigh the multiple factors some of which may conflict. According to the characteristics of limnetic products and limnetic products’supplier selection, combining quantitative and qualitative evaluation, finally the author identified 11 indicators to evaluate the supplier of limnetic product. The author used entropy value method to establish the simple and flexible model of limnetic product’s supplier selection. Finally the author calculated the index weight to find the best supplier by an example. It was proved that: people should pay more attention to the quality and the transport equipment when people chose limnetic products supplier. And using fuzzy mathematics method to estimate indicators would make the entropy value method play a more important role in supplier selection of limnetic product.
