基于CBR的新型飞机维修间隔辅助决策方法研究

Research on the New Aircraft Maintenance Interval Auxiliary Decision Making Method Based on CBR

采用基于案例推理的方法,为新型飞机制订维修大纲提供决策参考信息,使之更加智能和高效。针对不同飞机部件的维修间隔,选取不同的案例,对案例的主要信息进行加工提取。利用广义最近邻法对选取的案例进行检索,同时结合部件的特点进行修改以获取新的维修方案。最后,通过对国产新舟600机型转弯机构组件进行案例分析,验证了该方法的有效性。

Based on Case-based Reasoning method, this study can provide some reference information of decision making for the new domestic aircraft Maintenance Review Board Report revising staff, in or- der to make it more intelligent and efficient. According to aircraft components＂ different Maintenance In- terval, the author selects different cases, processing and extracting the main information of the cases. The researcher also retrieves the selected cases by using the Generalized Nearest Neighbor, and modifying it on the basis of the characteristics of components in order to make a new maintenance plan. Ultimately,to verify the rationality of this method, the thesis makes turn components of the new domestic aircraft MA600 as a Case Analysis.
