The forming-sintering process is the bottleneck of the magnetic material manufacturing system in general, which restricts the overall output of the workshop. It is hard to formulate a production plan due to the complex constraints in such production system. In current research, the production planning control framework integrated with DBR (Drum-Buffer-Rope) concept oriented for forming-sintering process is designed. Moreover, a heuristic method considering the constraints of the magnetic material production process is proposed, which standardize and optimize the preparation process of the forming-sintering production plan. The practical application indicates that the heuristic method greatly reduces the number of WIPs, shortens the order manufacturing cycle, and improves the on-time delivery rate and the utilization rate of the sintering furnace, as compared with the current planning method of the enterprise.
