需求扰动下一种供应链的优化决策

A supply chain optimization decision with demand disturbance

为了解决需求扰动下一类单级供应链的优化问题,采用求极值的方法,分析了需求扰动对供应链模型的影响.建立了在市场需求服从均匀分布条件下供应链的初始模型及需求扰动后的抗扰动模型,研究发现市场规模变化较小时,原有模型仍然能实现供应链协调;如果市场规模变化较大,初始模型不具备协调性,采用抗扰动模型能使供应链协调.

In order to solve the optimization problem of single supply chain under demand disturbance,this study analyzes the effect of demand disturbance on supply chain model using extremum method.The initial supply chain model under the uniform distribution of market demand,and anti-disturbance model after demand disturbance are established.The study finds that if the market scale is small,the initial model can achieve supply chain coordination;if the market size becomes larger,the initial model does not have the capability of coordination,and the anti-disturbance model should be used for supply chain coordination.
