Abstract:

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.
