主干航路网络规划方法

Trunk Route Network Planning Method Based on Improved Gravity Model

为了提高全国民航可用空域的利用率和运行效能,针对民航运输的特点,通过建立城市民航运输综合实力评价指标体系和阻抗函数对引力模型进行改进。应用改进的引力模型构建我国主干航路网络系统,并根据我国的城市地理分布对航路网结构进行优化调整。最后通过与现行网络的性能指标对比,证明利用改进引力模型构建和优化的航路网方案的网络安全性、网络总长度、航路利用率、网络连接度等指标都明显优于现行网络。

In order to improve the utilization of civil aviation airspace and the operation efficiency, the gravity model was improved by building comprehensive strength evaluation index system for a city＇ s civil aviation transpor- tation and impedance function. The trunk route network layout was constructed by using the improved gravity mod- el, and then optimized and adjusted according to the city distribution. At last, comparing the performance indexes with the current network, it proved that the final designed network is superior to that of current one on network se- curity, total length of network, utilization rate of route and network connectivity
