节点重要性是网络抗毁性分析中的重要内容。在分析现有节点重要性评估方法的基础上,研究了一种链路赋权网络的节点重要性评估方法。该方法既考虑了节点与邻接节点的连接紧密程度,同时也考虑了节点失效后对网络造成的破坏程度。最后通过实例对方法正确性进行了验证。
The node importance is an important content in analysis of the invulnerability of network. Taking consideration of the existing evaluation methods of node importance, an evaluation method of node importance of link-weighted network is studied. In this method, the close degree of connection between a node and its adjacent nodes is considered, meanwhile, the extent of At last, the accuracy of the evaluation method damage on network because of node' s invalidation is considered too. is proved with an example.
