中文摘要：

一条易逝品双渠道供应链中存在一个拥有线下渠道的零售商和一个拥有线上渠道的生产商,商品在流通过程中存在一定的路途损耗。当突发事件导致需求和生产成本同时扰动时,通过建立市场需求模型,求出扰动状态下供应链的最优渠道销售价格、销售数量以及生产数量,通过博弈论和合同理论的原理设计了改进收益共享契约。研究表明,改进收益共享契约可以用来实现易逝品双渠道供应链的应急协调,当突发事件导致市场规模和生产成本发生扰动时,易逝品双渠道供应链存在一定的鲁棒性。最后,给出算例验证了结论。

英文摘要：

This paper studies the dual-channel supply chain of perishable products consisting of a traditional retailer and a manufacturer,in which there is certain in-transit loss in its operation.The optimal sales price,the selling quantity and the production quantity can be given in our market demand model by the principle of game theory and contract theory when unexpected events suddenly happen and make the dual channel supply chain face demand and production cost disruptions.Then,an improved revenue-sharing contract is presented in this study.Our results show that：（1）the improved revenue-sharing contract can be used to coordinate the perishable product dual channel supply chain;（2）When unexpected events lead to the change of the market scale and the production cost disruption,there exists certain robustness in the perishable product dual-channel supply chain.Finally,some numerical examples are given to verify those conclusions.
