Abstract In this paper, a new rulebased expert system with multiple knowledge databases is designed according to the characteristics of the domain expert knowlege and its representation.Compared with classic expert system ,the new system has a number of corresponding knowledge bases according to the subproblems of a complex problem. And each knowledge base includes a shallow knowledge base of the empirical knowledge and a deep knowledge base of the scientific knowledge. The inference engine of the system adopts twolevel inferring structure, the inference at system level and the one of subproblem, which can reduce the searching space quickly and work efficiently.The system runs well over internet.
