A monitoring and rescheduling system for steelmaking and continuous casting (SCC) production is studied with the consideration of three functions as simulation, monitoring, and rescheduling. To classify the knowledge and enhance knowledge reusability, modularity knowledge management is used in this system. In this system, the monitoring and rescheduling knowledge of the SCC production are organized into a two-level tree construction, and a combination of object-oriented and rule-based representations is applied. Moreover, based on the characteristics of monitored disturbances, we present two rescheduling methods named time adjustment and machine reassignment. The former is designed for disturbances with weak influence by utilizing reserved times and flexible factors in the SCC production. The latter reassigns machines based on unused capacities of machines to eliminate serious disturbances. Simulation results demonstrate the proposed rescheduling algorithms are feasible and effective, and the system has well real-time capability to maintain the stability and continuity of SCC production.
