一种基于有向图的复杂系统可靠度计算方法

A New Reliability Evaluation Method of Complex System Based on Directed Graph

复杂系统的可靠度计算是可靠性工程研究的主要内容,传统的偏微分方程、概率统计和矩阵计算等运算较复杂,工程应用推广较差。作者提出一种基于有向图的复杂系统可靠度计算方法,该方法通过对成熟的系统可靠性框图进行改造、扩展和转化,使之变为直观、便于计算的有向带权图,从而有效解决复杂系统的可靠度计算困难问题。

Reliability evaluation of complex system has been more and more important in reliability engineering. The conventional methods are much too complex so that those methods cannot be widely used in reliability engineering. This paper constructs a new reliability evaluation model of complex system based on directed graph by transforming and improving system＇s reliability block diagram.The proposed model based on directed graph can help designers and engineers evaluate the complex system＇s reliability more effectively.
