Abstract Aiming at the three-level closed-loop supply chain system composed of manufacturers, recyclers and consumers, chaos control theory is used to solve the chaotic control problem of closed-loop supply chains under three channel recovery modes. Firstly, the uncertainty of consumer's demand for remanufactured products is considered, over a period of time, data on the number of consumer resourcepurchases of remanufactured products are collected. The method of K-S test proves that the data obeys the uniform distribution, and further constructs the discrete dynamic model based on the decision variable. Secondly, using MATLAB software to simulate numerical simulation, study the recovery price sensitivity coefficient and the recovery price competition coefficient as fixed values, the manufacturer and the two recyclers draw a fork map, the largest Lyapunov index map, the initial value sensitive analysis map, and the system's chaotic characteristics and primary value sensitivity analysis. Finally, the chaotic system is controlled by means of state feedback control and parameter adjustment. The results show that this method can effectively improve or eliminate chaotic state, optimize decision-making behavior and improve the profit of decision makers.
