基于修正Shapley值法的农产品供应链收益分配研究

Research on Revenue Distribution Mechanism of Agricultural Products Supply Chain based on Modified Shapley Value Method

当前我国农产品供应链表现出联盟不稳定性及运营成本高等特征。首先阐述了农产品供应链的主要参与主体及运作模式,分析了不同运作模式在收益分配上的差异。其次针对我国以多级批发模式为主的市场环境,在农产品供应链合作博弈问题中,考虑风险及资源投入因素对供应链收益分配的影响程度。再次构建基于修正Shapley值法的收益分配方式,反映供应链参与主体在资源投入、风险承担等因素对供应链收益的不同贡献率,提出基于风险承担能力以及资源投入水平差异的农产品供应链收益分配修正算法,解决了标准Shapley收益分配下供应链参与主体收益与贡献不匹配问题。最后,通过模拟算例验证了基于修正Shapley值法解决农产品供应链的收益分配问题的现实可行性。

At present,the supply chain of agricultural products in China exhibits the characteristics of alliance instability and high operating cost.Firstly,the main participants and operation modes of agricultural products supply chain were expounded,and the differences in income distribution of different operation modes was analyzed.Secondly,considering the market environment of multilevel wholesale mode in our country,the influence of risk and resource input factors on the income distribution of supply chain in the cooperative game problem of agricultural products supply chain was considered.Thirdly,an income distribution method based on the modified Shapley value method was constructed to reflect the different contribution rates of the supply chain participants to the supply chain income in terms of resource input,risk-taking and other factors.A modified algorithm for the income distribution of agricultural product supply chain based on risk-bearing ability and resource input level difference was proposed,which solves the problem of the mismatch between the income and contribution of supply chain participants under the standard Shapley income distribution.Finally,a simulation example was given to verify the practical feasibility of solving the income distribution problem of agricultural products supply chain based on the modified Shapley value method.
