摘　　要：针对航电计算平台的多态性、动态性的系统特点和不同计算性能的可靠度分析需求,在传统动态故障树分析方法的基础上提出了支持多态性分析的串行门、并行门、条件门,多态冷备件门,设计了一种多态动态故障树分析方法.采用该方法构建了一种典型架构航电计算平台的性能多态动态故障树,基于蒙特卡洛仿真对该多态动态故障树进行了求解.该方法可对航电计算平台不同性能要求下的可靠度进行定量分析,为航电计算平台的可靠性设计提供理论数据支持.In order to assess the performance reliability of dynamic and multi-state avionics computing platform, ＂serial gate＂, ＂parallel gate＂, ＂condition gate＂, ＂multi state cold spare gate＂ are propesed and a multi-state dynamic fault tree analysis methord is designed for multi-state system analysis. A multi-state dynamic fault tree of representative structure avionics computing platform is constructed using the dynamic fault tree analysis methord and calculated by Mento Carlo simulation. The multi-state dynamic fault tree analysis methord can evaluate performance reliability of avionics computing platform under different performance requirements, and can provide theoretical data for reliability design of avionics computing platform.
