基于双重容量识别标准的航空网络关键航段识别方法

Identification Method of Critical Routes in Aviation Network Based on Double Capacity Identification Standard

对航空网络中的关键航段进行有效识别存在传统识别方法单一,网络性能评价指标不全面等问题,提出一种基于双重容量识别标准的航空网络关键航段识别方法。通过建立脆弱识别标准和瓶颈识别标准,从航段容量变化对航空网络综合性能影响的角度对网络中的关键航段进行识别,并在网络性能评价阶段,采用一种基于AHP的航空网络综合性能评价指标,使用基于UE模型的空中交通流量分配模型,对该识别方法的有效性进行验证。结果表明:该方法能够对航空网络中的关键航段进行有效识别。

A method of identifying critical routes in the aviation network based on dual capacity identification standard is used for improving the singleness of the traditional identification method and incomplete evaluation index of network performance.The vulnerability identification and bottleneck identification standards are established to identify the critical routes in the network in the aspect of route capacity change on the overall performance of the aviation network.And a comprehensive network performance evaluation index based on AHP(analytic hierarchy process)is used for improving the evaluation effect of network performance.Finally,the validity of the identification method is verified by constructing an air traffic network traffic distribution model based on UE(user equilibrium)model.The results show that the method can identify the critical routes in the aviation network effectively.
