摘要:

如何依据部件的可靠性属性和系统的结构特性定量分析系统可靠性,是可靠性工程研究中亟待解决的重要问题之一。本文总结现有的系统可靠性分析方法,将其划分为4大类,即解析法、蒙特卡罗法、综合法和网络法,并对上述4种方法的优缺点及适用的系统进行了分析,最后指出将表征组成系统的各组份相互关系的拓扑结构和表征系统组份的节点可靠性属性相结合,构建新的可靠性测度指标评价系统可靠性是未来系统可靠性分析方法的研究趋势。

Abstract:

According to the structure of system and the reliability of components, how to analyze quantitatively system reliability is one of the important problems in reliability engineering. The methods of system reliability are summarized, and these methods are divided into analytical method, Monte Carlo method, the comprehensive method and the network method. Advantages and disadvantages of the four methods are analyzed and their application ranges are discussed. Finally, combined topological structure with reliability properties, new reliability measures are presented to evaluate system reliability, which is outlined as possible future directions.
