Fault Tree Analysis of Infrastructure Exposed to Natural Hazards

Infrastructure networks are not on secure industrial sites, but are routed across the land. The exposure of network sections to natural events (but also to intentional ones) depends on the spatial distribution and the characteristics of such hazards. The consequences are typically consid-ered in terms of human fatalities, but in the case of networks, such scenarios can be relevant only for a limited number of sections. Instead, it is also important to evaluate what may be the impact of a network failure for large communities in terms of economic loss or public impact. This work proposes a method based on Multi-State Fault Tree Analysis (FTA) for identifying the most critical sections and minimal cut sets of a network, and to evaluate the expected consequences in term of economic loss.
