Study for the Offset Printing Quality Control Expert System Based on Case Reasoning

The case-based reasoning is suitable for the solving of large scale, high intelligent and unstructured problems with complicated tasks because it could help us obtain knowledge conveniently, understand easily, and also could enlighten thinking. The case-based method was introduced in quality control field for the offset printing on the basis of the analysis of the quality influencing factors and rules in the process of offset printing. The feasibility whether case-based design (CBD) could be applied to the offset printing quality control system was analyzed; the systematic functional modular structure and working process based on CBD concept which had operability were put forward; the key technologies such as case present, case retrieval, case modification and study which were concerned in the process of system realization were discussed in detail
