ABSTRACT

The European Air Traffic Management Network is unique in its complexity due to numerous stakeholders, airspace configurations and accommodated traffic volumes. Such complexity challenges both tactical visibility and network resiliency in general. Therefore, we review different perspectives of resiliency and robustness to explore advantages of performance variability in understanding network states. The methodology is based on capturing emergent disruptions as drivers of performance variability. We claim that capacity regulations reveal restorative mechanisms for tactical planning. Consequently, we conduct statistical evaluations to provide quantitative measures for network state definitions. The methodology is even able to distinguish non-nominal disruptions to either crisis or critical states. The proposed approach is then demonstrated by a data sample covering six months. Furthermore, to assess the severity of non-nominal states, we estimate probability distributions for different regulation types. The study is concluded by addressing long-term network resiliency based on estimated probability distributions.

摘要

由于众多利益相关者，空域配置和可容纳的交通量，欧洲空中交通管理网络的复杂性是独一无二的。这种复杂性通常会挑战战术可见性和网络弹性。因此，我们回顾了弹性和健壮性的不同观点，以探索性能可变性在理解网络状态方面的优势。该方法基于捕获紧急中断作为性能可变性的驱动因素。我们声称能力法规揭示了战术计划的恢复机制。因此，我们进行统计评估以提供网络状态定义的定量度量。该方法甚至能够区分非标称中断是危机状态还是危急状态。然后，通过六个月的数据样本来证明所提出的方法。此外，为了评估非标称状态的严重性，我们估计了不同法规类型的概率分布。通过基于估计的概率分布解决长期网络弹性来结束本研究。
