面向铁钢对应的两级案例推理铁水动态调度系统

针对铁水动态调度的多扰动、实时性强等特点,以及铁钢对应对于铁水在时间、质量、成分、温度等指标上的要求,提出了基于两级案例推理的铁水动态调度系统体系结构。根据生产现场各种扰动的特点,对两级案例库进行了案例分类。研究了铁水动态调度系统的两级案例表示方法、案例检索与匹配、案例的调整及维护等关键技术,最后给出了两级案例动态调度结果满意度的综合评价指标。采用大量的生产现场数据对系统进行了测试验证,测试结果表明系统推理速度较快,稳定性较高,动态调度结果合理有效,两级案例推理的技术方法具有广泛的应用前景。

Two-stage case-based reasoning for molten iron dynamic scheduling system oriented iron-steel correspondence

Aiming at the features of having multi-disturbance and real time scheduling, framework of molten iron dynamic scheduling system based on two-stage case-based reasoning（CBR） is proposed according to the indices of molten iron oriented iron-steel correspondence, such as time, mass, composition, temperature and so on.In terms of characteristic of various disturbance of production site, two-stage case library is classified.Key technology of molten iron dynamic scheduling system including case representation, case retrieving, case adaptation and case maintenance is discussed.And the satisfaction evaluation indices of dynamic scheduling are computed.The experimental results using a lot of practical production data show molten iron dynamic scheduling system has velocity on reasoning, higher stability and validity on results.The technical methods of two-stage case-based reasoning have wide application prospects.
