摘　　要：在建立飞机维修仿真中的系统模型时,针对飞机系统中航线可更换组件(LRU)之间的逻辑关系难以表达并伴随多余度系统的问题,提出一种基于扩展可达矩阵的系统建模方法,并通过组件AGENT化的方法,表达了组件在系统中的逻辑和组件状态改变对系统工作逻辑的影响。该方法能抽象飞机系统逻辑,并转化为计算机可实现的对象。通过分析可达矩阵,可明确信号传递与受维修行为所关联的组件。最后,通过构建自动飞行系统(AFS)的逻辑功能模型验证了该方法的可行性。To build up the system model in aircraft maintenance simulation, a system modeling method is proposed based on extended reachability matrix together with component design of AGENT. It can not only solve the problem of the expression of logic relationship among the LRUs, but also can provide the system with redundancy. The method can describe the component＇s work logic in the system and the effect of component state change on the system. The logic of aircraft system can be abstracted and transformed into the effable object of computer with this method. Through the analysis of the reachability matrix, the component related to the behavior of the signal transmission and the behavior of the service can be defined. At last, the feasibility of the method is verified by constructing a logic function model of Automatic Flight System （AFS）.
