考虑延迟交货风险的易逝品供应链回购契约研究

Buy-back contract in perishable supply chain with delivery delay risk

考虑供应商延迟交货对终端顾客需求的影响,基于回购契约建立考虑延迟交货的供应链订货模型,并分析了延迟交货风险和需求风险的分担.研究表明:在供应商延迟交货的情况下实现协调的回购价格低于无延迟的情形;在实现协调的条件下,对于供应商而言,回购价格高而延迟交货罚金低的回购策略更有利;对于零售商而言则相反.供应商和零售商都愿意承担更多的需求不确定风险而承担较少的延迟交货风险.算例分析进一步验证了该研究结论.

Supply chain ordering model with delivery delay based on buy-back contract is established. The impact of delivery delay rate on the order quantity of supplier and retailer is analyzed as well as the profit. It is shown that the coordination buy-back price in delivery delay is less than that in non-delivery-delay. The supplier prefers high buy-back price and low delivery delay penalty, and the retailer prefers low buy-back price and high delivery delay penalty. Both of them are willing to share more demand risk and less delivery delay risk. Example analysis verifies the above conclusion.
