为挖掘出网络中的多个关键点,定义了网络资本和关键核。根据网络特点,确定影响函数和衰减函数来计算网络的网络资本值,以网络资本的变化来反应网络性能变化。根据投入产出分析的思想,提出了完全相关模型对网络的关键核进行挖掘,如果节点(集)动态删除后使网络性能下降到一定程度,则节点(集)为关键核。实验结果表明:当网络性能下降到原来的30%时,动态失效方法比按序失效方法挖掘关键核的点数少。本方法在对网络关键核的挖掘上更加准确和有效。
In order to dig out a number of key points in the network, the definition of network capital and key nuclear. According to the characteristics of the network, determine the impact function and attenuation function to calculate the network capital value of the network, changes in network capital to reflect changes in network performance. According to the idea of input-output analysis, a completely related model is proposed to mine the key nuclei of the network. If the network performance is reduced to a certain extent after the node (set) is dynamically deleted, the node (set) is the key kernel. The experimental results show that when the network performance drops to 30% of the original, the dynamic failure method is less than the sequential failure method to tap the key cores. The method is more accurate and effective in mining the key network of the network.
