Abstract�� According to the need of maintenance program development, a civil aircraft maintenance review board report (MRBR) development method was presented according as the latest maintenance steering group(MSG) ideals and the maintenance programs experiences of similar aircrafts. The method integrates case-based reasoning(CBR) with rule-based reasoning(RBR). A framework of civil aircraft MRBR expert system was constructed, and the critical technologies were discussed separately, including the case representation and structure, the case retrieval, the integration reasoning technology, case adaptation and storage. Case retrieval included two steps: firstly, searching the aircrafts in the case base as similar as possible, secondly, matching up to the most similar item from the similar aircrafts. The integrating reasoning was realized by the method that used CBR and RBR separately then compared their results to decision. The expert system was realized using object-oriented design, and the validity of the MRBR with hybrid CBR and RBR was demonstrated by applying the expert system to an aircraft in an airline.
Keywords�� rule-based reasoning   case-based reasoning   maintenance review board report   integrating reasoning technology   expert system
