摘要
建设国际航空枢纽作为实施民航强国战略的重要引擎,科学衡量枢纽功能以及优化枢纽机场航线网络成为建设任务的重要抓手。现阶段枢纽机场航线网络整体连通性差,导致运行效率低下、航线网络资源浪费等问题,成为航空枢纽建设进程中亟需解决的关键问题。本文建立枢纽机场航线网络连通性优化模型,该模型综合考虑航空公司经济成本和航班频率的约束,以枢纽机场航线网络连通性最大为目标函数,以吞吐量为依据对连通机场等级进行划分,旨在对不同层级机场的连通性进行优化。以广州白云国际机场为例,对白云机场国内客运航线网络连通性进行优化。结果显示,通过优化不同层级连通机场数量和航班频次,广州白云机场客运航线网络连通性提高了3.94%,总成本降低了1.57%。连通高质量的机场对枢纽机场连通性起关键作用,符合枢纽机场的特征需求,验证了模型的可行性和有效性。
Building an international aviation hub is an important engine for implementing the civil aviation power strategy,and scientifically measuring the hub function and optimizing the hub airport route network have become important drivers for the construction task.At present,the overall connectivity of the hub airport route network is poor,leading to low operational efficiency and waste of route network resources,which has become a key issue that urgently needs to be solved in the construction process of aviation hubs.This article establishes an optimization model for the connectivity of hub airport route networks,which comprehensively considers the constraints of airline economic costs and flight frequencies.The model takes the maximum connectivity of hub airport route networks as the objective function,and evaluates the connectivity level of connected airports based on their throughput.The aim is to optimize the connectivity of airports at different levels.Taking Guangzhou Baiyun International Airport as an example,the connectivity of Baiyun Airport′s route network is optimized,and data samples are collected from domestic passenger routes,without considering freight and international routes.The results demonstrate that the connectivity of the route network at Guangzhou Baiyun Airport is increased by 3.94%,and the total cost decreased by 1.57%,verifying the feasibility and effectiveness of the model.
