摘　　要：为提高供应链的运作效率,在市场需求为零售价格的线性函数假设下,考虑一个由单供应商单零售商组成的两级供应链,当干扰事件造成生产成本、市场规模和价格敏感系数同时扰动时,构建了一个两级供应链的博弈模型。研究了在集中化决策下供应链的最优应对措施,以及分散化决策下当供应商为Stackelberg博弈主导者情形时的供应链的协调机制。研究结果表明,在稳定情形时供应链制定的生产计划有一定的鲁棒性,但当扰动超过一定的范围时,供应链应该调整生产计划并设计新的契约才能达到协调。通过算例验证了相关结论。To improve operation efficiency of supply chain,when production cost,market scale and price sensitivity coefficient were disrupted simultaneously,a game model of two-echelon supply chain with single supplier and single retailer was established on the assumption that demand was linear function of retail price.The optimal strategies under the centralized mode were studied,and the coordination policies were provided when the supplier and retailer participated in a Stackelberg game as the supplier was the leader under the decentralized mode.Research results showed that the original production plan of the supply chain with no disruption had certain robustness under a small disruption.However,as the disruptions exceeded a certain range,the original production plan was changed and the new contracts should be designed to coordinate the supply chain.Finally,a numerical example was given to illustrate the conclusions.
