| 摘 要： | 大型复杂系统完成规定任务往往涉及多个阶段,并且在不同的任务阶段,系统通常由其各级子系统、单元以不同的功能组合形式构成,因而,其可靠性逻辑结构(框图)也随时间的改变而改变。当连续多阶段系统不能分阶段单独处理时,将引出所谓的时段延续相关性问题。本文重点研究了时变结构多阶段任务系统的时段延续相关性问题,对典型时变结构的可靠度进行了分析,提出了有效的解决方法并建立了相应的数学模型。研究成果已应用于某大型测控系统的可靠性分析任务中

| Abstract: | Phased missions system involves several mission phases(or stages). The stage modulars will be relative to each other, and can not be treated independently as usual. This paper studied this problem, proposed some typical time varing structures for phased missions system with relative stage modulars. Using these basic structures, we can model phased missions system and compute its mission reliability exactly. The results have been used successfully. |
