Availability of Repairable Communication Network Based on k/n(G) System

基于k/n(G) 表决系统的可维修网络系统的可用度分析,将k/n(G) 表决系统引入通信网络抗干扰中。假设系统部件均处于正常工作状态时t=0;在t→0的时间间隔内一个部件状态发生变化,系统用时间连续状态离散的马尔可夫过程表示,建立可维修网络系统模型。计算系统状态概率和可用度以确定最佳的故障检测率,达到最佳的综合效率。

An availability analysis method for repairable network system based on the k/n(G) is introducing the k-out-of-n:G system into the anti-jamming study of communication network. Under the suppose of all component operating normally at t=0; in the time interval Δt→0 only one component state has changed. A complex system could be modeled as Markovian process which has a state discrete-time of continuously time-homogeneous. The Markov抯 system state probability and system availability are calculated to determine the best failure detection rate, and therefore the higher comprehensive efficiency is achieved.
