多阶段任务系统可靠性建模研究

Research on the reliability model for phased mission system

摘要:

随着系统复杂性和自动化程度的提高,多阶段任务系统(PMS)的应用越来越多。与单一阶段系统相比,PMS的可靠性分析由于阶段之间的相关性而变得更加复杂。在对PMS作简要介绍基础上,文中对PMS可靠性建模的故障树方法作了系统描述,并以某个多阶段系统为例,进行了比较计算分析。

Abstract:

With the raising of systematic complexity and automation level, the application of Phased Mission System (PMS) increases. Comparing with unitary stage system, the reliability analysis of PMS becomes more complex because of the correlation between stages. After brief introduction for PMS, this paper builds the fault tree model for PMS reliability analysis. Taking certain PMS as an example, several calculation methods are compared.
