【摘要】：研究了由单供应商和多个竞争性零售商组成、供应商产出随机且生产投入量不受零售商控制的二级供应链协调问题,决策变量为供应商的生产投入量和零售商的订购量。证明了整个供应链期望利润是生产投入量和订购量的凹函数,阐释了分散决策下的供应链存在双重边际化效应,并从风险分担的角度提出了能协调供应链的回购和成本风险分担契约。理论分析了该契约的协调条件,并在一定条件下,供应商和零售商的期望利润将获得帕累托改进。最后,通过数值算例验证了上述结论的正确性。
[Abstract]:This paper studies the coordination problem of a two-level supply chain composed of a single supplier and a number of competitive retailers whose output is random and the production input is not controlled by the retailer. The decision variable is the production input of the supplier and the order quantity of the retailer. It is proved that the expected profit of the whole supply chain is a concave function of the production input and the order quantity. This paper explains the double marginalization effect of supply chain under decentralized decision, and puts forward the contract of repurchase and cost risk sharing which can coordinate the supply chain from the point of view of risk sharing. The coordination conditions of the contract are analyzed theoretically. Under certain conditions, the expected profits of suppliers and retailers will be improved by Pareto. Finally, the correctness of the above conclusions is verified by numerical examples.

【正文快照】： 供应链协调旨在系统利润最大化,然而现实生活中的各个供应链成员为各有目标的独立决策个体,供应链往往存在双重边际化效应[1-4]。因此,需要建立有效的协调机制以集成所有个体,使得:(1)供应链成员共担风险;(2)整个供应链利润达到最优。常用的协调机制有回购契约[5]、收益共享契
