[Abstract]:In this paper, the model predictive control method is used to study the cooperative model of closed-loop supply chain network under uncertain conditions, and the algorithm is solved. A three-level closed-loop supply chain considering remanufacturing and return and a closed-loop supply chain considering the recycling center are analyzed, with emphasis on the production and inventory control of the closed-loop supply chain. The corresponding mathematical model of inventory balance is constructed and the model predictive control method in control theory is used to carry out production and inventory control. The simulation curve is ideal and the bullwhip effect is reduced and the expected purpose is achieved. It provides theoretical guidance for the production and inventory control of closed-loop supply chain. The main work of this paper is as follows: first, the background of the closed-loop supply chain is expounded, the current situation and shortcomings of the closed-loop supply chain research in China are analyzed, and a new research direction is put forward. The basic theory of closed-loop supply chain is summarized systematically, including: the concept of supply chain, the definition of reverse logistics, and then extends to the concept, background, implementation and field of closed-loop supply chain, design principles, implementation issues, etc. Through two typical closed-loop supply chain operation mode to discuss the image. Third, the basic theory of model predictive control is expounded. The research status of model predictive control in supply chain is summarized briefly. The problem of bullwhip effect is introduced. Fourthly, the inventory equilibrium state space model is established for a three-level closed-loop supply chain considering remanufacture and return. The unconstrained and constrained cases are solved respectively. The performance curve of production, inventory and bullwhip effect is obtained. Fifth, the inventory equilibrium state space model of a closed-loop supply chain considering recovery center is established, and then the state estimation and prediction are introduced, and the objective function is introduced. The necessary formulas are deduced, and then an example is given to solve the unconstrained and constrained cases. The performance curves of production inventory and bullwhip effect are obtained. Finally the innovation points of this paper are summarized and the limitations of this paper and the direction of further improvement and further research are pointed out.
