基于联合契约的供应链协调与抗突发事件研究

Study on Supply Chain Coordination and Emergency Prevention Based on Associated Contracts

针对由一个制造商、一个分销商和一个零售商组成的简单三级供应链,考虑随机市场需求下,首先建立了一个使供应链协调的基于回购契约和收益共享契约联合使用的联合契约机制,并讨论了节点企业间的利润分配情况;其次分析了突发事件导致市场规模发生变化时三级供应链受到的影响:当需求变化比较大时,供应链在原有契约机制下的协调将被打破;最后通过调整联合契约的契约参数,使供应链重新协调,具有抗突发事件性;最后给出具体算例。

In this paper, in view of a simple three-echelon supply chain composed of one manufacturer, one distributor and one retailer and considering the stochastic market demand, we first established the associated contract mechanism based on buyback contracts and revenue-sharing contract, discussed the allocation of supply chain profit among the nodal enterprises, then analyzed the impact of changes in market scale caused by outbreak events on the three-echelon supply chain, adjusted the parameters in the contract to re-coordinate the supply chain, and at the end, presented a specific numerical example.
