Integration of CBR and RBR in fault diagnoses of missile electronic command system

Due to the complexity of the mobile missile electronic command system (MMECS), applying the single method in system fault diagnose can hardly achieve satisfactory results. Based on the characters of MMECS, the fault diagnosis system combining the case-based reasoning (CBR) method and the rule-based reasoning (RBR) method is presented. The framework of the mixed reasoning system and the case presentation are put forward. The question of redundancy reasoning is solved. Finally, with the example of voice interrupt, the system's correctness and validity is proved. It is shown that the system is suitable for both the operators training and online decision making for the army.
