航空相依网络的弹性测度与分析

The Resilience Measurement and Analysis of Aeronautical Interdependent Network

针对航空系统多维性、多属性、协调性以及系统在遭受恶劣天气、军事活动和流量限制等干扰下系统维持自身性能问题,采用相依网络对航空系统建模,并应用相关指标分析航空相依网络的弹性以及弹性敏感源。结合算例,研究表明航空相依网络的结构弹性主要受机场网络、管制扇区网络影响,随机去除节点更能降低网络的弹性;网络的功能弹性主要受机场网络与管制扇区网络影响;航空相依网络的弹性敏感源是机场网络、管制扇区网络。相依网络能较好反映航空系统间的关联关系,航空相依网络的弹性与网络拓扑结构与交通流分布相关。

For the multi-dimensionality, multi-attribute, coordination of the aviation system and the system to maintain its own performance problems under the disturbance of severe weather, military activities and flow restrictions, the network is modeled by the interdependent network;the relevant indicators are used to analyze the network resilience and resilience sensitive sources. The elasticity of the interdependent network and the source of elastic sensitivity. Combined with the example, the research shows that the structural flexibility of the aviation interdependent network is mainly affected by the airport network and the air control sector network. The random removal of nodes can reduce the resilience of the network. The functional resilience of the network is mainly affected by the airport network and the air control sector network. The elastic sensitive source of the network is the airport network and the air control sector network.Interdependent networks can better reflect the relationship between aviation systems. The elasticity of aviation interdependent networks is related to the topology of network and traffic flows.
