摘　　要：考虑突发事件导致市场价格随机波动,构建应急数量弹性契约下的三级供应链模型,求解最优订货和定价策略.同时,构建无突发事件和市场价格稳定时的供应链模型,探索不同情景下供应链协调状态的变化情况.另外,控制弹性系数为变量,分析弹性系数变化对于供应链整体收益及决策的影响.研究结果表明:当弹性系数为常量时,仅存在唯一的最优订货策略,只有对基准契约进行适当调整才能协调应对突发事件.若弹性系数为变量,仅存在唯一的供货决策,但却有多组最优订货方案.最后,通过算例仿真验证了上述相关结论,证明了弹性系数的变化不会影响整个供应链系统的最优收益.Considering the random price condition caused by emergency,a three-stage supply chain model under the quantity flexibility contract was constructed to solve the optimal ordering and pricing strategy.Meanwhile,the models of no-emergency and market price stability were established to explore the changes of supply chain coordination under different scenarios.In addition,flexibility coefficients were changed as a variable to analyze the impact on the overall revenue and related parties'decisions.The results showed that,there is only one optimal ordering strategy when the flexibility coefficients are constant.Only by adjusting the benchmark contract properly,could we coordinate the response to emergency.When the flexibility coefficients are variable,there is only a single supply decision,while the unique optimal ordering decision does not exist.Finally,a numerical example proved that changes of flexibility coefficients would not have influence on the overall optimal revenue.
