管制扇区复杂网络特性与抗毁性分析

Characteristics and Invulnerability Analysis of Control Sectors Complex Network

提高空中交通管制效率是解决航班延误的有效方法.从空中交通管制的基本单元——管制扇区——入手,运用复杂网络理论,以扇区为节点,空间位置相邻的扇区依据航班联系设边,建立管制扇区复杂网络结构.以华北区域管制中心所辖空域为例实证分析,该网络的平均路径长度和聚集系数均比较小,度分布相对平均,强度、介数累计分布符合特定函数规律.研究扇区网络的抗毁性,找出对网络抗毁性影响最大的指标,并以此确定关键扇区和潜在关键扇区.

One valid way to solve the flight delay problem is improving the efficiency of air traffic control(ATC). With the aspect of control sectors,the basic units of ATC system, using the method of complex networks, an ATC sectors network is established, which considers the sectors within a certain range of airspace as nodes and the relationships between each other of flight as edges. Furthermore, the Area Control Center of North China is given as an example to verify the property of small average path length and small clustering coefficient. The distribution of degree is pretty homogeneous, which is different from strength and betweenness whose distribution conform to some functions. This paper will also study the survivability of sectors and indicate the significant metric, which determines invulnerability the critical sectors and the potential critical sectors.
