基于微元故障树的多阶段任务系统可靠性分析方法

Reliability Analysis Method of Phased Mission System Based on Micro-element Fault Tree

随着多阶段任务系统(PMS)的广泛应用,系统的多阶段任务特性研究也就显得越发必要和紧迫。考虑设备多模式失效情况,提出了一种基于微元故障树的可靠性建模与预计方法,用于解决多阶段任务系统可靠性分析问题,并以某典型多阶段任务系统为例验证方法的可行性。该方法为复杂系统可靠性评估提供了一个更加简单高效的实施途径。

With the extensive application of phased mission system(PMS),the study of systems′phased mission characterization becomes more and more necessary and urgent.Considering the situation of equipment′s multi-mode failures,a method for reliability modeling and prediction based on the micro-element fault tree is proposed for solving the reliability analysis problem of phased mission system.And the feasibility of the method is verified with a typical phased mission system as an example.This method provides a simpler and more efficient implementation for complex system reliability assessment.
