Node Importance Evaluation in Ground-Based Civil Aviation Navigation System Based on Complex Network Theory

Abstract

Ground-based civil aviation navigation facility network has the characteristic of connection preference. With the continuous expansion of the network, the nodes in the network will appear Matthew Effect. In order to enhance the capacity of Air Traffic Service (ATS), it is necessary to evaluate the vulnerability and Business continuity of network nodes. Identifying the key nodes in the network can provide the basis for vulnerability evaluation and expansion planning of the network. Thus, it is important for improving the Business continuity of Air Traffic Control(ATC) support system. Considering the relationship among navigation stations, we construct a weighted complex network model based on the weight of the air traffic flow. Through analyzing the degree and degree distribution of the navigation facility network in China’s southwest control area, the key nodes of the facility network are obtained.
