摘要
阶段任务系统(PMS)是一种典型的复杂系统,包含了一系列具有时间连续且不相互覆盖的基本任务阶段,对其系统可靠性的评估是一项复杂的工作,国外已经开展了20多年。在对PMS的几种可靠性模型进行了讨论和分析的基础上,从系统效能的角度出发,从理论上给出了一种新的评估各阶段转换时间随机的PMS系统可靠性的模型,并通过计算机仿真进行了大量次的计算,最后对仿真结果进行了分析。
PMS is a typical kind of complex system, which consists of consecutive and non-overlapping time periods phases, it is difficult to evaluate its system reliability although it has been studied for more than 20 years abroad. The model of reliability for PMS is discussed and analyzed. At last, a new model in evaluation of reliability for PAlS is carried out based on system efficiency, then large amounts of simulation computing is executed and the simulation results are thoroughly analyzed.
