需求扰动下供应链契约协调机制研究

本文根据需求扰动的影响力大小,将其分为日常需求扰动和突发需求扰动,并对比了两种不同需求扰动的产生原因和特征;具体阐述了需求扰动是如何对供应链上各企业造成影响的,并给出了两种不同的传导模式;通过剖析需求扰动风险传导机制,从3个角度提出了针对需求扰动的控制策略;最后,通过建模探讨了在需求扰动后价格敏感系数改变的情况下零售商对产品价格的调整。同时,为了保证零售商按发生需求扰动后的最优订购量订购产品和按最优产品零售价给产品定价,根据需求扰动不同的影响程度,分类讨论了与供应链相协调的适用契约。

Study on Contract Coordination Mechanism for Supply Chain Based on Demand Disruption

Based on the influence degree of demand disruption,this paper divides the demand disruption into the daily and the sudden,and contrasts the causes and the characteristics of these two kinds of different demand disruption.And it discusses how the demand disruption influences the member firms in a supply chain,and gives two conduction patterns of demand disruption.Through analyzing the conduction mechanism for demand disruption risk,it proposes the control mechanism for demand disruption from three aspects.Finally,in a circumstance that the price-sensitive coefficient is affected by demand disruption,it discusses how retailers adjust the product price through modeling.In order to ensure retailers order products based on the optimal order quantity after demand disruption,and price products based on the optimal retail price,it discusses the suitable contracts coordinated with supply chain according to the different influence levels of demand disruption so as to maximize the profits of supply chain.
