Research On The Profit Distribution Of Supply Chain Considering The Factors Of Effort And Risk Type Under Fair Entropy

Along with the rapid development of economic globalization and changeable supply chain management mode,the competitions among enterprises have changed into the competitions in supply chains,enterprises can achieve complementary advantages and enhance the competitiveness of the supply chain through cooperation.In order to realize the effective cooperation of supply chain,it is necessary to fully coordinate the relationships among cooperation partners,the most effective tool to coordinate supply chain business relationship is the supply chain contract,so the research of supply chain contract has became the focus of supply chain management.The supply chain activities,the risk preferences of members and how to distribute the profit of supply chain are hot topics in the research of supply chain contracts,this paper studies optimization model and its solving problem of getting revenue sharing ratio based on maximum fair entropy under two important cooperation environments of supplier and retailer,and the fair and reasonable profit allocation strategy between supplier and retailer is given.At first,basing on revenue sharing contract model based on cost sharing,the optimal revenue sharing ratio of revenue sharing contract based on cost sharing is obtained based on the fair entropy model,then the fair and reasonable profit allocation strategy between supplier and retailer is given.Secondly,the retailer is the loss aversion type,and the supplier conducts the supply chain effort activities as the cooperative environment,the effort level,the order quantity and the wholesale price decision of the centralized decision-making model,the wholesale price decision model and the traditional revenue sharing decision model are analyzed,the improved revenue sharing contract model based on the effort cost sharing and reduce the wholesale price strategy is designed,and Pareto improved decision is obtained,also,the optimal revenue sharing ratio and the fair and reasonable profit allocation between supplier and retailer of the improved revenue sharing contract are obtained by the fair entropy model,sensitivity analysis is made for the important parameters of the model.In the end,the supplier is the loss aversion type,and the supplier conducts the supply chain effort activities as the cooperation environment,the effort level,the order quantity and the wholesale price decision of the centralized decision-making model,the wholesale price decision model and the traditional revenue sharing decision model are analyzed,the improved revenue sharing contract model based on Pareto improved decision,the effort cost sharing and reduce the wholesale price strategy is designed,also,the optimal revenue sharing ratio of the improved revenue sharing contract are obtained by the fair entropy model,then the fair and reasonable profit allocation strategy between supplier and retailer is given,sensitivity analysis is also made for the important parameters of the model.
