Evaluation model based on support vector machine for green coal supplier in electric power supply chain

The green supplier evaluation is of great importance for the green supply chain management. Unlike other industries, the thermal power supply chain has its own characteristic, therefore the green coal suppler evaluation models should differ from those of other industry. In this paper, an evaluation index system for green coal suppler is established according to the characteristic of the thermal power supply chain. Then, the principle component analysis (PCA) is used to create the main evaluation indexes and support vector machine (SVM) is adopted for the evaluation model. The practical examples show that the model established in this paper outperforms others in evaluation accuracy.
