最小通路法在通信保密装备可靠性建模中的应用

Minimal Paths Method and Its Application in Encryption Equipment Reliability Modeling

针对通信保密装备可靠性建模难度大的问题,提出了一种新的适用于复杂系统的可靠性建模方法—最小通路法。通过在系统拓扑结构图上搜索出所有能够使系统正常工作的最小通路,建立系统的可靠性模型。该方法基于广义的网络拓扑结构,因此网络的源节点和目标节点不必局限于严格的定义,可以随意指定,具有很大的灵活性。实例证明,该方法可行有效。

The minimal paths method, which is appropriate to model the reliability of the complex systems, is presented in this paper to solve the difficulty in modeling the encryption equipments＇ reliability. In this proposed method, to search all minimal paths in the system topology which may make them work, the reliability model is established. Since it is based on general network topology, both the source nodes and the destination nodes may be given with relaxed definition, and it can be specified optionally. Finally, an illustrative example is shown that this method is feasible and effective.
