| Abstract: | By combining AI Iogic reasoning and database technology,a failure analysis expert system based on typical aeronautical equipment failure cases and human analysis experience is introduced in this paper.such system requires the knowledge of metal material,mechanics,structure/component design,and facture analysis,etc.First the function and structure of the system are described,followed by the details in relational database management for failure case base,rule base and failure term dictionary.The knowledge discovery and acquisition methods for failure analysis rules are pointed out,and the practical useful uncertainty reasoning model for making failure analysis decisions is given.The effectiveness of the approcach has been proven through several application examples. |
