網絡抗毀度和節(jié)點重要性評價方法:針對現(xiàn)有評價模型無法準確評價某些典型網絡抗毀度和節(jié)點重要性的問題，提出一種基于全網平均等效最短路徑數(shù)的網絡抗毀評
價模型，全網平均等效最短路越多，網絡的抗毀能力越強。在此基礎上，提出一種節(jié)點重要性評價方法，如果節(jié)點失效后網絡抗毀度下降
越多，則該節(jié)點在網絡中的重要性越大。
關鍵詞：網絡拓撲；抗毀度；平均等效最短路；節(jié)點重要性

【Abstract】Compared with the topology of full-connected network, a method for evaluating network invulnerability is proposed based on average
equivalent shortest way. It shows that the more the average equivalent shortest ways are, the better the network invulnerability is. A method to
evaluate node importance is proposed based on invulnerability degradation percentage after one node being destroyed. The larger the percentage is,
the more important the node is.
【Key words】network topology; invulnerability; average equivalent shortest way; node importance
