A two-layer air traffic dynamic network based en route cascading failure propagation dynamics modeling and multi-dimensional impact analysis

Abstract

This study proposes an en route cascading failure propagation dynamics model based on a two-layer air traffic dynamic network by characterizing the dynamic interaction between the spatial–temporal transmission of air traffic and the evolution of the en route network structure due to failure propagation. On this basis, a multi-dimensional impact analysis method is conducted to evaluate the overall impact of cascading failures from various aspects, including network structure, control service capacity, traffic demand, and operational efficiency. A case study of an en route network in Shanghai demonstrates the effectiveness of the proposed cascading failure evolution framework in successfully capturing the dynamic process of failure propagation and self-recovery, as well as the accuracy of the proposed multi-dimensional impact analysis method to better reflect the overall impact of cascading failures in the en route network.
