摘要
针对炼钢连铸的生产特点,研究了炼钢连铸动态调度专家系统。系统通过混合知识表示形成知识网络,构建树状层次结构实现知识库模块化管理,运用推理机实现动态调度策略实时推理,加强了系统的柔性和知识的重用性。系统能够根据调度方案和生产数据实时监控生产过程,及时识别扰动,并实现重调度。仿真结果表明,系统具有很好的实时性和交互性,能够保持生产的稳定运行。
According to the production characteristics, a dynamic scheduling expert system of steelmaking-continuous casting is studied and designed. The system adopts a hybrid knowledge representation to form knowledge network, and builds up tree hierarchy architecture to manage knowledge base modularly. Real-time reasoning for dynamic scheduling strategy is implemented by inference mechanism. These techniques enhance the system flexibility and the knowledge reusability. The system can monitor production process in real time based on schedules and production data, and identify disturbances timely, then reschedule if needed. The simulation results demonstrate the well real-time and interactive features of this system which can maintain stable operation of prodaction.
