Resilience or Robustness: Identifying Topological Vulnerabilities in Rail Networks [article]

Alessio Pagani, Guillem Mosquera, Aseel Alturki, Samuel Johnson, Stephen Jarvis, Alan Wilson, Weisi Guo, Liz Varga
2018 arXiv   pre-print
Here, we examine whether the different topological measures of resilience (stability) or robustness (failure) are more appropriate for understanding poor railway performance.  ...  The results show that resilience and not robustness has a strong correlation to the consumer experience statistics.  ...  Resilience of Weighted and Directed Networks We introduce a parameter for quantifying the resilience of weighted directed networks measuring their trophic coherence.  ...
