Abstract: In a hybrid system with product recovery,the producers have to coordinate the manufacturing and remanufacturing simultaneously.With the integrating remanufacturing activity into regular production environment,traditional production planning and inventory management methods are no longer suitable.How to design an effective control mechanism is a key problem for the producers in the product recovery context.This paper puts forward an improved control mechanism for hybrid system by redesigning the inventory information.Moreover,considering the system complexity,we apply automatic control theory to develop transfer function models of hybrid system.The dynamic simulation shows that our control mechanism can not only effectively coordinate manufacturing and remanufacturing activities,but also substantially improve the systems performance.
