中文摘要：

研究一个供应商和一个面临指数需求的零售商组成的供应链系统的协调问题．首先证明收益共享合约在稳定条件下能实现该供应链协调；当突发事件导致零售商面临的需求规模和供应商的生产成本同时发生扰动时，供应链的协调被打破，提出了一体化决策时调整生产计划和零售价格的协调策略；进一步证明了改进的收益共享合约可协调需求和成本同时扰动的分权供应链；数值实验表明了模型的有效性．

英文摘要：

The coordination problem of a supply chain with one supplier and one retailer who is confronted with exponential demand was studied. It is proved that a revenue sharing contract can be used to coordinate the supply chain under normal environment. But the coordination may be broken off when demand scale of retailers and production costs were disrupted simultaneously, and the optimal strategies about adjusting price and production quantity replied to the disruptions is proposed under the centralized decision-making. It is also proved that the improved revenue sharing contract can coordinate the decentralized decision-making supply chain when demands and costs are disrupted simultaneously. Finally, a numerical example is presented to illustrate the efficiency of the proposed model.
