基于云重心Shapley值的供应链融资联盟收益分配研究

针对Shapley值法在供应链融资联盟收益分配过程中分配因素考虑不全以及各分配因素随机性和模糊性强的缺点，本文利用云重心法修正Shapley值的收益分配。根据供应链融资联盟收益分配的主要影响因素，在传统的Shapley值法的基础上引入了风险系数、投入成本、努力程度以及信息对称水平4个分配修正因子，弥补了影响因素的缺失，并利用云重心法计算各联盟企业的收益修正值，云重心法能够解决定性指标和定量指标之间的模糊性转换，极大克服了Shapley值法自身的局限性。算例对比结果发现，改进的Shapley值法能更加合理的分配收益，有利于维持供应链融资联盟的稳定。

Research on Supply Chain Financing Income Distribution Based on Shapley Value With Cloud Gravity Center

In view of the disadvantages of Shapley value method in the process of income distribution of the supply chain financing alliance that the factors considered are not full and the randomness and fuzziness of the distribution factors are strong,we use the cloud gravity center method to revise the income distribution of Shapley value in this paper.According to the profit influencing factors of allocation in supply chain finance alliance,risk coefficient,cost effort and information support level four correction factor are introduced in the basis of the traditional Shapley value method so as to make up for the lack of influence factors,and the Cloud Gravity Center method are used to determine the correction value of each distribution factor,the cloud gravity center method can solve the fuzzy trans formation between the qualitative and quantitative indicators,greatly overcoming the limitations of the value of Shapley.Finally,through an example,it is found that the improved Shapley value method makes the distribution more reasonable,which helps to maintain the stability of the supply chain financial alliance.
