Contrasting critical infrastructure resilience from swedish infrastructure failure data

• Critical technical infrastructures constitute the backbone of society by providing essential services to vital societal functions and the community at large, hence it is of essence that these are resilient. Critical infrastructures, e.g. power systems, telecommunication systems and railway systems, are designed and operated based on different philosophies of where to put the resilience emphasis, robustness, rapidity of recovery or a combination of the two. Here empirical failure data, such as duration and consequence of disruptions, from several critical infrastructures in Sweden are explored and analysed. To facilitate comparisons, a generic resilience assessment approach is also presented and applied. The results give insight to the resilience level of different infrastructures in Sweden and a basis for an exploration of its reasons, e.g. due to difference in regulatory schemes, design or risk cultures. It is concluded that there exist significant differences of infrastructures resilience levels and the factors shaping the resilience.
