The Newcastle University research output collection, currently available on ePrints, will shortly be moving to a new open repository platform, Figshare. To prepare for the data migration we have paused adding new content to ePrints, and will resume once the new repository is launched. During this time you will continue to have access to ePrints (but no new content will appear). We will share updates here when available.

Abstract

Our modern communities are becoming increasingly reliant of the services that are provided by our infrastructure systems. The functioning of these systems is particularly important after a major disaster and can either aid, or hinder, rescue efforts and longer term recovery plans. These systems consist of many components and each is designed to have a particular probability of failure. Whilst this design approach is satisfactory under normal operating conditions, when these systems become damaged (in an earthquake for example) it is likely that some components will have failed, but it is the ability of the system to continue to provide some level of service that is considered important. In this paper, we introduce a new approach, using network graph theory, which has previously been used to model the complex interactions between components in social and biological networks. The paper shows how traditional network graph theory can be modified to model infrastructure systems with greater accuracy; including the development of spatial models and the inclusion of a flow element within the analysis.
