【摘要】：研究了随机农产品产出受生产努力影响、随机需求受销售努力影响且供应商的生产投入量不受零售商控制的供应链全局最优化问题。论证了集中决策下存在唯一的最优解,分析了批发价格契约和回购契约的协调性。研究结果表明,二者均不能协调供应链,但回购契约激励了订购量和生产投入量的增加,减弱了供应链的双重边际化效应。进而在回购契约的基础上,从风险分担的角度构建了回购和成本风险分担组合契约,该契约不仅能实现供应链协调,且在一定条件下,各供应链成员的利润获得了帕累托改进。数值算例验证了以上结论的正确性,并对以上三种契约进行了比较分析。
[Abstract]:The global optimization problem of supply chain in which the output of random agricultural products is affected by production effort, the random demand is affected by sales effort and the production input of suppliers is not controlled by retailers is studied. The unique optimal solution under centralized decision is proved, and the coordination between wholesale price contract and repurchase contract is analyzed. The results show that neither of them can coordinate the supply chain, but the repurchase contract stimulates the increase of order quantity and production input, and weakens the double marginalization effect of supply chain. On the basis of repurchase contract, this paper constructs the combination contract of repurchase and cost risk sharing from the angle of risk sharing. This contract can not only realize the coordination of supply chain, but also improve the profit of each member of supply chain under certain conditions. Numerical examples verify the correctness of the above conclusions, and the above three contracts are compared and analyzed.
