Abstract: Abstract In this chapter, a modelling framework for interdependent technical infrastructures is presented. As input to the framework, characteristics of interdependencies and the objectives of the modelling framework are discussed. The overall approach is to divide the modelling of technical infrastructures into two parts, a topological part and a functional part. The topological part describes the structure and how components are connected. The functional part describes the flow of the infrastructure and how the system reacts when strains affect it. This generic approach of how to model individual infrastructures then enables the inclusion of dependencies in and analyses of a “system-of-system” model. Three perspectives of vulnerability analyses are also presented: global vulnerability, critical components and geographical vulnerability. The presented framework is utilized in, but not limited to, the context of vulnerability analyses in Chap. 6 for two different types of interdependent technical infrastructures.
