Abstract: Deeply analyzing the requirements of invulnerability evaluation on communication network, and according to the problem that the existing invulnerability evaluation model is unable to evaluate invulnerability measure node importance and the invulnerability on networks of different numbers of nodes, an improvement is made combined with the evaluation method of node importance with respect to multiple performance measures based on the shortest route number. In addition, an invulnerability measure evaluation model of whole network average equivalent based on nodes is proposed with it, which is validated to be effective.

Key words: network topology, node importance, shortest route, invulnerability measure

摘要： 分析了现代战场通信网抗毁性评价的需求，针对现有通信网抗毁性测度评价模型无法准确评价网络抗毁性测度和节点重要性，以及不同节点数的网络间抗毁性的问题，利用基于最短路径数和跳面节点法节点重要性多指标评价方法对该模型进行改进。在此基础上，提出一种基于节点的全网平均等效抗毁性测度的网络抗毁性评价模型，并验证了模型的有效性。
