A supply chain optimization decision with demand disturbance

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.
