Abstract: Drum-Buffer-Rope scheduling method (DBR) and simulation tool ARENA were used to simulate the production process in a case of end-of-life home appliance's remanufacturing system. The simulation model of DBR was established and the dynamic checking for the remanufacturing production process was implemented. It was explained in detail how to make use of the DBR model founded to identify and eliminate the resource constraints, and therefore improved the recourse utilization rate and benefits of remanufacturing system. Outcomes from experimental simulations show that the DBR model enables to come true identifying and eliminating recourse constraints and their influences. By offering the optimal value of Buffer Size of DBR model, the phenomenon of queue delaying in the unit of constraint is eliminated and the supply uncertainty of remanufacturing system goes lower, meanwhile the objective functions as Recourse Utilization rate and Net Profit are also optimized.
