| Abstract: | The “intelligent guide completeness process rule tree” is put forward for knowledge expressing mode and storage structure based on thorough research on aerial electronic instruments and fault diagnosis expert system. It implements the function of completely recording the experience of expert troubleshooting, and a method of diagnosis supporting rule-tree is designed. The method can simulate expert thought truly and automatically by operating computer. It has been applied in an important national project successfully. It is proved that the system can improve the accuracy and rapidity of detecting faults; meanwhile, the method is general for some system fault diagnosis in other fields. |
