面对价格敏感性突变的供应链协调应对策略研究

Coordination of Supply Chain with Price Sensitivity Disruption

研究突发事件造成需求的价格敏感性突变时，供应链的协调应对问题。采用线性函数的形式衡量突发事件造成的额外成本，分析得到供应链的最优生产计划调整策略和最优价格调整策略，从而获得突发事件后供应链的最优利润。并设计了全单位数量折扣契约和限值线性价格契约，激励供应商和零售商实现协调应对，并满足按批量进行数量折扣的运营需求。此外，还对比分析了供应链在市场规模突变与价格敏感性突变下应对规律的异同。最后，通过数值仿真计算，展示结论的应用。

The coordination scheme for a supply chain was investigated under demand disruption which can change the price sensitivity of market demand. The deviation costs induced by the disruption were evaluated by linear function. Then, the optimal production strategy and pricing scheme were developed to get the best profit after the disruption. Also, the wholesale o quantity discount policies and capacitated linear pricing policy,which can discount in bulk,were designed to motivate suppliers and retailers to realize coordinated results. Moreover, the similarities and differences between the marketing scale disruption and the price sensitivity mutation were analyzed. Finally, by the numerical simulation, the application of conclusions was demonstrated.
