本文提出了一种有效的非相位任务系统可靠性分析的解析建模方法。PMS是在其任务期间包含多个连续且不重叠的任务阶段的系统，在复杂的技术系统中大量存在，如航空航天系统、核电站和高性能计算系统。由于系统配置和组件行为的动态性以及各阶段的统计依赖性，对PMS进行精确的可靠性评估是一项耗时且复杂的任务。本文提出了一种基于多值决策图（MDD）的可靠性分析新方法，该方法适用于所有阶段都涉及相同数量的部件，但每个阶段所需的工作部件数量可能不同的不可修复pms。为了快速构建PMS MDD模型，提出了一种新的MDD生成方法。系统组件不一定相同；它们的故障时间分布可能是异构的。举例说明了所提出方法的应用和优点。
In this paper, an efficient analytical modeling method is proposed for reliability analysis ofk-out-of-nphased-mission systems (PMSs). A PMS is a system involving multiple, consecutive and non-overlapping phases of tasks during its mission, which abounds in complex technological systems such as aerospace systems, nuclear power plants, and high-performance computing systems. Due to dynamics in the system configuration and component behavior as well as statistical dependences across phases, exact reliability evaluation of a PMS is a time-consuming and complicated task. This paper proposes a new efficient multi-valued decision diagram (MDD) based method for the reliability analysis of a special class of non-repairable PMSs calledk-out-of-nPMS where the same number of componentsnis involved in all the phases but the required number of working componentskmay vary from phase to phase. Particularly, a new MDD generation method is proposed for a fast construction of the PMS MDD model. The system components are not necessarily identical; they can be heterogeneous in their failure time distributions. Examples are provided to demonstrate the application and advantages of the proposed methodology.
