Homogeneity Analysis of Multiairport System Based on Airport Attributed Network Representation Learning

基于机场属性网络表示学习的机场群同质化分析

The homogeneity analysis of multi-airport system can provide important decision-making support for the route layout and cooperative operation.Existing research seldom analyzes the homogeneity of multi-airport system from the perspective of route network analysis,and the attribute information of airport nodes in the airport route network is not appropriately integrated into the airport network.In order to solve this problem,a multi-airport system homogeneity analysis method based on airport attribute network representation learning is proposed.Firstly,the route network of a multi-airport system with attribute information is constructed.If there are flights between airports,an edge is added between airports,and regional attribute information is added for each airport node.Secondly,the airport attributes and the airport network vector are represented respectively.The airport attributes and the airport network vector are embedded into the unified airport representation vector space by the network representation learning method,and then the airport vector integrating the airport attributes and the airport network characteristics is obtained.By calculating the similarity of the airport vectors,it is convenient to calculate the degree of homogeneity between airports and the homogeneity of the multi-airport system.The experimental results on the Beijing-Tianjin-Hebei multi-airport system show that,compared with other existing algorithms,the homogeneity analysis method based on attributed network representation learning can get more consistent results with the current situation of Beijing-Tianjin-Hebei multi-airport system.

现有机场群研究较少从航线网络分析角度进行机场节点之间的同质化分析,航线网络中机场节点的属性信息考虑不足。为了解决此问题,文中提出了一种基于机场属性网络表示学习的机场群同质化分析方法。首先,构建包含属性信息的机场群航线网络,如果机场之间有航班,则为机场之间添加一条边,并为每个机场节点添加航线区域属性信息。其次,分别进行机场属性以及机场网络向量表示,通过网络表示学习方法将机场属性和机场网络表示向量嵌入到统一的机场表示向量空间,得到融合机场属性以及机场网络特性的机场特征向量。通过计算机场群内机场向量的相似度,可以方便地计算机场之间以及机场群的同质化程度。京津冀机场群数据集的实验结果表明,与目前其他算法相比,本文提出的基于属性网络表示学习的同质性分析方法可以得到更符合京津冀机场群现状的同质化计算结果。
