Evaluation and analysis of resilience and frangibility for transportation networks
交通网络弹复度与易碎度的测算与分析

Resilience is the ability of a system to return to the normal state after a strong perturbation from failure, disaster or attack. Resilience Engineering is a hot topic attracting many researchers. A reliable independent path-based resilience evaluation approach for transportation networks is designed and recommended. The concept and evaluation approach of frangibility are introduced to represent the importance of edge or node failure to the whole network. To study the properties of independent paths, resilience and frangibility, we also prove several theorems. The evaluation approaches are applied to evaluate the resilience and frangibility of the railway network in China mainland. The location rules of the nodes and edges with highest resilience or frangibility are discussed. Some interesting conclusions are presented.
