| 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. |
