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.

- In this chapter, the modelling framework presented in Chap. 5 will be used to perform vulnerability analyses from three perspectives: global vulnerability, critical components, and geographical vulnerability. Two case studies of two real-world interdependent infrastructure systems are performed; one focusing on an electric distribution system coupled with a water distribution system, and one focusing on a railway system which is composed of seven interdependent systems.

Bokkapitel (refereegranskat)abstract
- This chapter presents methods for analysing interdependencies in critical infrastructures. In general, there are three groups of methods for analysing interdependencies; (1) conceptual, (2) model and simulation and (3) empirical and knowledge-based approaches. Examples of methods belonging to these groups are presented. The latter part of the chapter discusses challenges related to modelling, focusing on how to deal with complexity, trade-offs between abstraction and fidelity, choice of consequence measures and obtaining information.
