航空加权网络抗毁性综合评估方法

摘要

According to the disadvantage of present study about network survivability,such as single index,unweighted network,a muti-index airline network survivability evaluation method is proposed.The method is based on network flow,and contraposed the trait of airline network.Among the indexes,the robust measurement is given out based on network throughput,the network efficiency measurement is given out based on similarity weight network flow,and the adaptation measurement,is given out based on weight distribution of nodes' adjacent edges,which reflected the positive survivability.At last,the paper conducts checking by establishing northwest region airline network the experimental analysis shows that the realistic airline network has the similar property with star topology,which has better network efficiency but worse robustness.And as central nodes for Xian yang and Urumchi,they have better positive survivability.The method is verified through simulation.%根据目前网络抗毁性研究中指标单一、网络无权等不足,针对航空网络的特点,以流量为边权,提出了一种多指标的航空网络抗毁性评估方法.基于网络吞吐量、相似权网络流量、节点相邻边权重分布分别构建了鲁棒性度量、网络效率度量、网络适应性度量.最后通过建立西北地区航空网络进行仿真,结果表明:西北地区航空网络具有与星型网络相似的性能,鲁棒性较差,网络效率较好,咸阳和乌鲁木齐作为中心节点,具有较好的主抗性能.实验结果证明了该评估方法的有效性.
