To address the issues of extensive inventory management strategies and irrational invento-ry structure for repairable spare parts in manufacturing enterprises,a two-echelon inventory control model for repairable spare parts based on the(S,Q)strategy is constructed.Considering the actual conditions of manufacturing enterprises,a two-echelon supply and maintenance support model based on the(S,Q)strategy is proposed,aiming to optimize cost savings while meeting service level constraints.For criti-cal spare parts in manufacturing enterprises,a two-echelon inventory control model for repairable spare parts is built upon the Metric model.In terms of algorithmic solution,a multi-population genetic algo-rithm is designed to solve for order quantities and reorder points.Using enterprise data for case analysis,the established inventory model is compared with traditional inventory models to verify its effectiveness.The results analysis indicate that the constructed inventory optimization model can reduce inventory costs by 48%while maintaining the service level,providing decision support for inventory management of re-pairable spare parts in large-scale manufacturing enterprises.
