摘要
航空运输业的快速发展对空中交通系统提出了更高的要求,但也提高了系统整体性能优化成本并降低了系统可实施性。选取影响力大的重要节点进行局部优化,在提高系统整体性能的同时,降低了工作量及成本,提高了系统可实施性。采用复杂网络理论对空中交通管理系统进行建模,计算网络性能和介数中心性,评估网络影响力节点,分析影响力节点对整个网络性能的影响。最后,以中国东北地区空中交通系统为例进行分析,当改变影响力节点时,网络临界值RC比非影响力节点大20%,其中具有相同影响力的航路节点对网络性能的影响比机场节点大,因此通过对航路节点进行合理分流可提高网络性能。
The rapid development of air transport industry has put forward higher requirements for the air traffic system,the overall system performance optimization costs are increased,the system feasibilities are decreased.By selecting the influential node for local optimization,the overall system performance is improved,the workload and the cost are decreased,and the system feasibilities are increased.The air traffic management system is modeled by the complex network,the network performance and the betweenness centrality are calculated,and the influence of network influential node on the whole network performance is analyzed.Finally,a air traffic management system in the northeast of China is analyzed.By changing the influential node,the network threshold RCis 20% more than the non-influential nodes.Among them,the route nodes with the same influence have a greater influence on network performance than the airport nodes.Therefore,the network performance can be improved by reasonable shunt of the route nodes.
