N+K形式冗余备份通信系统的可用度分析

Analysis of Availability of the N+K Redundancy Back-up Communications System

文中利用随机Petri网对n+k形式冗余备份通信系统进行了综合分析,分析过程充分考虑了系统的动态变化和工程中的实际情况,建模过程简单直观,而且通过PIPE软件的仿真,得出了通信系统可靠性评价的一系列结果。该方法为工程人员设计系统的配置提供理论依据和数值依据,为促进配置资源的最优组合提供了较好的参考。

This paper comprehensively analyses redundancy backup communication system of n＋k form by using Stochastic Petri net. The author fully considers of dynamic changes in system and actual situation in project in the analysis process. The modeling process is simple and intuitive and gains results such as reliability evaluation of communication system by emulation PIPE software. This method not only provides theoretical basis and data basis for engineering personnel to design collocation of systems, but also provides relatively bettor reference to promote collocation of Optimal Combination.
