Vulnerability analysis of interdependent critical infrastructures: case study of the Swedish railway system

Vulnerability and resilience of transport systems – A discussion of recent research

“…Blizzards and heavy storms have a geographical extension and often disrupt more than one mode of transport and possibly other infrastructure systems. There are some studies attempting to analyse geographically extended effects (Jenelius and Mattsson, 2012) and interrelationships within and between systems with applications to track-based systems (Johansson et al, 2011;Zhang et al, 2014) and to road systems (Hémond and Robert, 2010;Hsieh and Feng, 2014). Further methodological development in this respect seems to be an interesting avenue of future research.…”

“…There are also three important perspectives of vulnerability analysis: global vulnerability analysis (Johansson et al, 2007), critical component analysis and critical geographical locations analysis (Wang et al, 2013). Considering infrastructures are always distributed in a wide spatial range, Johansson et al (2011) propose geographical vulnerability analysis to study the spatially oriented vulnerability involved.…”

Vulnerability analysis of complementary transportation systems with applications to railway and airline systems in China

“…The economic theory based approaches regard each infrastructure system as an entity in a market of economy and then model their interdependencies by economic models, such as input-output models and computable general equilibrium models, which enable to analytically study how perturbations propagate among interconnected infrastructures and how to implement effective mitigation efforts [33][34][35][36][37]. The network based approaches model each involved system by a network and describe their interdependencies by interlinks, which enable to describe the topological features of interdependent systems and flow characteristics upon systems, identify the critical system components and provide suggestions on mitigation strategies at detailed topological levels [38][39][40][41][42][43][44]. However, these studies mainly considered negative effects of interdependencies, where failures in one system can propagate to other systems and aggravate the initial damage.…”
