摘要
为研究关键航路点的失效成本,给空管和航空公司提供决策支持,基于我国航路网结构,从机场间的连通时间成本出发,提出基于改航可达性的关键航路点识别算法,将识别出的关键航路点与其他网络指标下的关键航路点进行抗毁性仿真对比。研究结果表明:中西部连接处航路点失去通行能力后,航班绕飞的时间成本较大,具有较大的改航可达性;A461、G212、A593等主干航路上的航路点拥有较大的加权改航可达性,总时间成本较大;识别出的关键节点拥有较大的度和介数值;基于度值和加权改航可达性的连续攻击对航路网破坏较大。
In order to study failure cost of key waypoints and provide decision-making support for air traffic management departments and airlines,on account of China’s air route network structure,a key waypoint identification algorithm based on diversion accessibility was proposed from perspective of transit time between airports.Then,the key waypoints identified were compared with those under other network indicators for invulnerability simulation.The results show that aircrafts have greater diversion accessibility when midwest connection nodes lose their traffic capacity,and their time cost of diversion is high.Waypoints on main routes such as A461,G212 and A593 have greater weighted diversion accessibility,and total time cost is high.Those identified key waypoints have larger degree and intermediate value.And continuous attacks based on degree value and weighted diversion accessibility cause bigger damages to air route network.
