Abstract: In order to model and manage the diagnosis and maintenance knowledge created for R&D of complex product, a method of knowledge modeling was proposed aimed to utilize the knowledge effectively. Firstly the concept of knowledge unit was put forward, and the concept of knowledge scenario and knowledge modeling were defined based on knowledge unit. Knowledge model was used to describe different structural forms of knowledge units under different knowledge scenarios. Then the diagnosis & maintenance knowledge unit model and pattern of knowledge organization based on product structure tree were set up, and the methods of knowledge reuse and knowledge discovery were provided. Finally the application system model was established and an example was adopted to verify the proposed method.

Key words: knowledge modeling, failure-free design, knowledge management, fault diagnosis
