A Synthesized Evaluation on Supply Chain Risk Based on Variable-Weights Extenics Matter-Element Model

In view of the supply chain risk evaluation has become the hot-issue and nodus about the supply chain risk management, and it is difficult to embody the requirements about balanced and incentive by the constant weight synthesize in evaluation, then set up a supply chain risk evaluation model based on variable-weights extenics matter-element, by combining the extenics theory with the variable-weights theory; and apply this model to evaluate the risk of Hengrui supply chain, based on the risk evaluation factors in the supply chain system, which supposed by the author. The results of the evaluation shows that the model not only overcomes the drawbacks of constant weights synthesize, motivate some key influenced factors, but also shows that the model has good scientificity, flexibility and effectiveness.
