Abstract
In this chapter, the modelling framework presented in Chap. 5 will be used to perform vulnerability analyses from three perspectives: global vulnerability, critical components, and geographical vulnerability. Two case studies of two real-world interdependent infrastructure systems are performed; one focusing on an electric distribution system coupled with a water distribution system, and one focusing on a railway system which is composed of seven interdependent systems.

Breadth first searches can be contrasted against depth first searches. Breadth first searches start in a node and find adjacent (neighbouring) nodes, the algorithm then continues to search in all these adjacent nodes before moving on and searching these nodes’ neighbours. Contrasted against a depth first search where a single path from the start node to neighbouring nodes is explored, that is, only one neighbour at a time is considered and the search continued for.

The Swedish Railway Administration was in 2010 replaced with the new Swedish Transport Administration.
