Abstract

The interdependencies among critical infrastructures are frequently characterized not only by logical dependencies and resource flows but often also require consideration of geospatial interactions among the infrastructure elements and surroundings such as the terrain, properties of the terrain, and of events involving the infrastructure such as fire and flooding. Modeling such events and interactions also requires the use not only of three-dimensional geospatial models but also a more precise characterization of both events and the interaction of events with the geospatial model to capture e.g. the resistance of different terrain features to blasts. In this paper we therefore present an extension to a graph-based model reported previously which allows the consideration of geospatial interdependencies and interactions in a specific area of interest. The model incorporates physical characteristics of both the infrastructure elements itself and of terrain and environment in a three-dimensional framework allowing for detailed analyses which cannot be captured using simpler spatial buffering techniques as found in many geospatial information systems.
