基于Shapley值法和信息熵的再制造闭环供应链利润分配研究

合理地对再制造闭环供应链中各企业进行利润分配,不仅可以提高各企业和供应链整体的效益,而且增强企业在供应链中参与运作的积极性。由于影响供应链企业利润分配的因素不是单一的,而Shapley值法的利润分配模型仅考虑各个企业对供应链整体效益的贡献率,而不能反映出其他因素对利润分配的作用,因此,文章在Shapley值法模型的基础上,综合企业的资本投入、风险因素和对环境的影响这三方面在利润分配中的作用,建立了综合策略利润分配模型,利用信息熵确定四种利润分配策略的权重;并以某再制造闭环供应链中的制造商、零售商、再制造商为例进行利润分配,证明了该方法的有效性。

Research of Profit-distribution of reproduction closed-loop supply chain based on Shapley value and information entropy

Reasonable profit-distribution in each enterprise of reproduction closed-loop supply chain can not only increase the profits of each enterprise and the whole supply chain,but also strengthen the enthusiasm of operation of each enterprise in the supply chain.There isn＇t only one factor that can influence the profit distribution of each enterprise in the supply chain.Profit-distribution mode based on the method of Shapley value considers only each enterprise＇s contribution to the whole profits of the supply chain,which can＇t reflect other factors＇ role in profit-distribution.Therefore,based on the Shapley value mode,considering the role of capital investment,risk factor and influence on the environment in profit-distribution,profit-distribution mode of comprehensive strategies is constructed.Information entropy is used to set the weight of four profit-distribution strategies.Producers,retailers and reproducers in reproduction closed-loop supply chain are used as examples to distribute profits.This method is proved effective in this paper.
