摘要/Abstract

摘要： 树形拓扑结构是网状拓扑结构的特例,即空间故障树(SFT)是空间故障网络(SFN)的特殊形式。研究更广泛的系统的可靠性与影响因素的关系,将SFT理论中系统结构的树形表示改为网状表示,形成SFN。给出SFN的性质、基本结构及其与SFT转化方法。SFN的结构包括一般网络结构、多向环网络结构及含有单向环的多向环网络结构。由于单向环的特殊性,具有循环连锁发生故障的特征,无法单独构成SFN,因此将其加入多向环网络结构形成含有单向环的多向环网络结构。重点论述含有单向环的多向环网络结构的表示方法和故障概率计算方法。研究结果表明:构建的SFN可处理具有网络结构的故障发生过程,同时SFN可转化为SFT,进而可利用SFT现有理论方法分析故障过程。

Abstract: The tree topology is a special case of the network topology,that is,the SFT is a special form of the SFN.In order to study the relationships between system reliability and influencing factors,the tree representation of system structure in SFT theory is changed to network representation and SFN is established.The properties,basic structure of SFN and its transformation method to SFT are given.The SFN structure includes the general network structure,the multidirectional ring network structure and the multidirectional ring network structure with a unidirectional ring.Because of the particularity of unidirectional ring network structure,it has the characteristics of the cycle linkage fault and is unable to form a SFN alone.Therefore,unidirectional ring network structure is added to the multidirectional ring network structure to form a multidirectional ring network structure with a unidirectional ring.This paper focuses on the representation of the multidirectional ring network structure with a unidirectional ring and the method for calculating its fault probability.The results show that the constructed SFN can handle the fault process with network structure,and that SFN can be transformed into SFT,and then the SFT's existing theoretical method is used to complete the fault process analysis.

Key words: safety system engineering, space fault network(SFN), space fault tree(SFT), unidirectional ring structure, fault probability calculation
