网络通信系统的信息脆性结构的研究

摘要

From system brittleness research point of view, this paper defined all the factors and incidents in a system,which can influence the system and arouse the system brittleness, as brittleness environment. These factors and incidents can cause sudden collapse of the system. Based on the brittleness of the system environment, the paper established the network communication system brittleness structure model. Combined with brittleness entropy,process of information brittleness risk in a network information system was analyzed. The result of the analysis shows the practicable of the method. The effectiveness and stability of the system information brittleness structure analysis method were proved in the paper. In the end, through building analysis model of main brittleness factor, the paper applied the analysis method to a specific network information system,and obtained satisfactory results.%从研究系统脆性的角度出发,把系统的环境中所有作用于系统上的并有可能激发系统的脆性,造成系统突然崩溃的因素和事件称之为系统的脆性环境.基于系统的脆性环境建立了网络通信系统脆性结构模型,结合信息脆性熵对网络通信系统进行信息脆性风险过程分析.分析结果表明此方法是可行的;论证了系统信息脆性结构分析方法的有效性和稳定性,最后将这套分析方法应用到一个具体网络通信系统,对其主脆性因子建立了分析模型,并取得了比较满意的结果.
