Aiming at characteristics of dynamic supply chain management under networked manufacturing, distributed model predictive control was applied to solve dynamic optimization control in supply chain. Firstly, implementing mechanism of dynamic supply chain was expatiated, and complete, stochastic, dynamic optimization models as well as the control constraints were proposed. Secondly, a distributed model predictive control algorithm was proposed, and a model of the optimal control sequence was established. Finally, the simulation example results show that the order rate of every stage can be calculated by distributed model predictive control, and the ideal stock of every stage in the enterprise can be predicted based on it, such can quick response to the dynamic changes of the market, and effectively control uncertainty in supply chain management.
