为评估本地网络的可靠性,深入分析了本地网络的特点和影响网络可靠性的因素,应用层次分析法构建了本地网络可靠性评估模型,提出了反映不同层次的可靠性测度指标,构建了层次比较的判别矩阵,采用特征根发确定了各测度指标的权重。结果表明,网络的拓扑结构和设备的可靠性是影响本地网络可靠性的关键因素,在进行本地网络设计时应优先进行评估。
In order to assess the reliability of the local network, this paper deeply analyzes the characteristics of the local network and the factors that affect the network reliability. By using analytic hierarchy process, a local network reliability assessment model is constructed, and the reliability measures of different levels are proposed. Comparison of the discriminant matrix, using the characteristics of hair to determine the weight of each measure index. The results show that the topology of the network and the reliability of the equipment are the key factors affecting the reliability of the local network. In the design of the local network, priority should be given to the assessment.
