【Abstract】 Taking Gear Failure Diagnosis Expert System as an example, the authors of this paper discuss in detail the characteristics of the Knowledge Bases of Diagnostic Expert System. A modular structure of Knowledge Bases is proposed. The modularity makes the bases easy to manage and revise. The system is used to simulate man’s mode of thinking. Two modules—Certainty Factor (CF) prodution and quantitative diagnosis — are constructed, and with them the system can solve problem induced by fuzzy conceptions in diagnosis.更多还原
