Sårbarhetsanalys av samberoende infrastrukturer med användning av nätverksmodellering

Modern technical infrastructures are an essential part of today's modern society. In this report a case study is made where the vulnerability of two interdependent infrastructures, namely a water distribution system and an electricity distribution system, is analyzed using a model based on network theory. The aim of this is to 1) determine what dependencies are present between these two infrastructures 2) study the vulnerability of these two systems, both with and without interdependencies and 3) evaluate what difference interdependencies might have on the outcome of the vulnerability analysis. The main conclusions are, though based on some crude assumptions, that it is important to include interdependencies in vulnerability analysis of technical infrastructure and that the utilized modelling apprach is suitable for this kind of analysis, although improvements can be made.
