Abstract: Modern society depends on increasingly complex infrastructure systems for survival. The failure of these, even for a short period of time, can lead to economic and social hardships for an affected population. Infrastructure systems are complex network structures that are distributed spatially over large areas. These networks are complex enough when considered singularly. However, many disaster events, natural and man-made, result in damage to network components which in turn cause failures in adjacent networks not directly affected by the original event. The complex interdependent relationships that exist between critical infrastructure networks mean that outages due to component failure can quickly spread beyond the confines of a single network to adjacent networks. These dependencies are overlooked in many existing models. A review of work carried out by GNS in the area of interdependencies modelling is presented as part of an ongoing programme of work. (auth)
