VMI下供应链应对突发事件的协调策略

Coordination strategy of Supply Chain under Disruption with VMI

研究在VMI下由一个供应商和一个零售商组成的供应链,利用改进的供应链契约来协调应对供应链中的突发事件.供应商管理库存下的供应链正常运作时,供应商和零售商运用剩余补贴契约来使供应链中的利润得到合理分配.然后,讨论了突发事件造成市场需求变大和变小的情况下,供应链不能通过原契约达到协调.进而,对原契约进行了改进,证明了改进后的剩余补贴契约可以使供应链重新达到协调.并用实例分析了供应链就突发事件前后的利润变化情况,说明了剩余补贴契约和改进后的契约的合理性和操作的方便性.

Under the VMI, the two level supply chain composed of a single supplier and a single retailer can use the supply chain contract to coordinate the emergency response. In the case of supplier management inventory and supply chain under normal operation, the supplier and the retailer use the surplus subsidy contract to reasonably distribute the profit of the supply chain. Discussed after the occurrence of unexpected events, the market demand change and market demand changes, supply chain profit status, and analysis of the supply chain by using the modified surplus subsidy contract, the profits of the supply chain before and after the change. After analysis, the modified contract can make the emergency achieve coordination. Finally, numerical analysis is used to verify the validity and rationality of the original surplus subsidy contract and the modified contract.
