| Abstract: | The correlation, the concept and the types of knowledge in the fault diagnosis of complex systems are firstly described systematically. Then the acquisition ways and an integrative organization model of different knowledge are discussed and studied such as the qualitative and quantitative knowledge, shallow and deep knowledge, fuzzy and dynamic knowledge. The object-oriented way of diagnosis knowledge representation for causality, structure, and model is also proposed. At last, an intelligent fault diagnosis theory and strategy is developed which utilizes synthetically different kinds of diagnosis knowledge and can improve the veracity and efficiency of diagnosis effectively. |
