摘要

摘要:
针对空中交通体系结构复杂、耦合性强、脆弱性高的特点，为缓解因受扰导致的级联失效现象，对其结构韧性进行研究。建立了空中交通信息物理系统(CPS)模型，提出同层度与层间度、同层介数与层间介数等指标，分析级联失效过程；提出空中交通CPS韧性的概念，并采用定量评估方法对受损能力和恢复能力进行度量；对比不同扰动-恢复策略下的空中交通CPS表现，制定最佳恢复策略，提高受扰时的韧性。以华东地区空中交通CPS为例进行分析，结果表明：空中交通CPS网络度分布服从幂率分布，介数服从指数分布；在基于介数度值扰动下，采用介数恢复策略可以有效提高受扰时空中交通CPS的韧性。

Abstract:
An air traffic network is a multi-dimensional complex system, which becomes vulnerable due to the coupling relationship when disturbed. This research examines the structural resilience of the system to mitigate the cascading failures caused by disturbance. An air traffic cyber physical system (CPS) model is developed. The relevant indicators such as the intra-layer degree and inter-layer degree, and intra-layer betweenness and inter-layer betweenness are defined, and the cascading failure process is analyzed. The resilience of air traffic CPS is then proposed, and a quantitative assessment method is used to measure the system’s disturbance response and recovery capabilities. The performance of the air traffic CPS is compared under different perturbation-recovery strategies to improve its resilience when perturbed. The results show that the air traffic CPS network degree follows a power law distribution while the betweenness follows an exponential distribution. For both perturbation methods, betweenness recovery leads to fastest recovery of air traffic CPS performance.
