With an aim at the dynamic uncertainty of demand and the complexity of multi-echelon inventory management in a supply chain,and by combining demand forecasting,forecast error tracking,improved scatter search algorithm and system simulation,a heuristic tracking simulation-optimization approach is proposed to achieve the collaborative optimization of the multi-echelon inventory system,and the simulation optimization model of a multi-echelon inventory decision-making system for supply chain is constructed by using Simulink tool software.Through simulation tests under different demand fluctuation modes and compared with the existing simulation optimization methods,the experimental results show that the proposed method has achieved better performance,and can provide an effective analysis reference for the decision-making of supply chain multi-echelon inventory system.
