Study on the Application of SVM in Purchase Supplier Selection

Supplier selection is one of the most important things in supply chain management. The process of choosing a suitable supplier will effect enterprise's production and quality directly. However, the process is complicated and takes a long time to get the final weights of suppliers. This article builds up an evaluation criteria system to evaluate suppliers, then, puts forward a new model (support vector machine, SVM) of supplier selection based on analysis the problem of supplier management. It calculates the weight and sort of each supplier to select appropriate suppliers. At last, a numerical simulation is used to explain selection of kernel function and sample training; the result reveals that this new method is practical and realistic.
