针对零售商为损失厌恶者的二级供应链,考虑突发事件导致商品市场需求和市场价格均随机波动,分别构建应急数量弹性契约的集中和分散决策模型,得出突发事件下供应链系统实现协调的最优决策,并探讨契约弹性幅度、批发价和损失厌恶程度的变化对于零售商最优订货策略和供应链上各成员利润的影响.研究结果表明,在合理的区间范围内调整契约弹性幅度和批发价均能使得突发事件下的供应链协调发展.最后通过算例验证了所得结论的正确性.

英文摘要：

This paper considers a two-stage supply chain with the loss-adverse retailer, among which the demand and market price fluctuate randomly with emergencies. Then the models of centralized and decentralized systems are constructed under the emergency quantity flexibility contract, and the equilibrium solutions of supply chain under emergencies are obtained.Also, the influence of flexibility range, wholesale price and loss aversion extent on retailers＇ optimal ordering decision and supply chain members＇ profits is discussed. The results show that the supply chain can be coordinated if the flexibility range and the wholesale price are adjusted within the reasonable section. Finally, the numerical examples verifies the correctness of the conclusion.
