中文摘要：
考虑需求扰动对双渠道供应链决策及协调机制的影响，在稳定条件下提出双渠道供应链的收益共享协调合约。当市场需求发生扰动时，通过求解供应链系统最优利润的Karush—Kuhn—Tucker（KKT）条件，提出一体化双渠道供应链的最优价格及数量决策，并分析了调整价格策略的价值；提出改进的收益共享合约协调突发事件下的分散化双渠道供应链；最后数值实验检验了模型的有效性。
英文摘要：
This paper investigates the impacts oi demand disruption on prlctng decisions and coordination in dual-channel supply chain. Firstly, we adopt a revenue sharing contract to coordinate the dual-channel supply chain without demand disruptions. Moreover, we examine how the dual-channel supply chain is priced and coordinated by solving the Karush Kuhn-Tueker （KKT） conditions of total profit when the demands of retail and direct sale both are disrupted. In the case, we analyze the effects of demand disruptions on prices, quantities and profits and derive the value of knowing demand disruptions in the centralized supply chain, and present the coordinating revenue-sharing contracts in decentralized decisions. Finally, the proposed models are further analyzed through numerical examples.
