摘　　要：在网络系统可生存性的四个关键属性基础上,采用层次化分析方法,将网络系统自上而下分成软件、硬件及运行环境三个影响因素层,提出了一套可提取、可观测、可操作的指标体系,并通过适当的算法进行量化计算,对结果进行分级评估分析,能在量化评估结果中反映网络可生存属性。通过实验验证,该指标体系使网络系统可生存能力量化评估更可行,使评估结果更有工程指导意义。On the basis of four key attributes of the network system viability,analytical hierarchy process is used to divide the network system from top to bottom into three factor layers of software,hardware and running environment,and a set of extractable,observable and maneuverable index system is proposed.A proper algorithm is applied to perform quantitative calculation,and the results are analyzed by a graded evaluation,which can clearly reflect the key attributes of the network system viability.Verified by experiment,the proposed index system of network system viability quantitative evaluation is more feasible,which makes the evaluation results more significant to the guidance of engineering.
