| Abstract: | The two-stage case-based reasoning (CBR) is proposed to realize stability of the dynamic real-time scheduling system of iron and steel works. The frame structure presentation is used to describe complex scheduling problems in iron and steel production. By introducing decision tree idea to cluster cases, the nearest neighbor (NN) algorithm is used to retrieve case. The techniques such as adopting O-O idea to adapt case, evaluating cases by the fuzzy theory, and the primary method of case maintaining are discussed. The computation experiment shows that the developed prototype system can satisfy the requirement of practical production on velocity, validity and stability. |
