Keywords: Critical infrastructure, network models, interdependent systems, vulnerability assessment, infrastructure PRA

The present PhD work aims to provide contributions to the assessment of critical infrastructure risk. Firstly, by improving use of network models in vulnerability assessments of critical infrastructure. This included investigating:

•  how to better model spatial disruptions
•  characteristics significant in improving robustness of interdependent systems
•  presenting an example of developing a real-world model of dependent infrastructure systems in a poor data setting.  

Secondly, by exploring the feasibility of a full PRA for complex infrastructure systems and highlighting how more common methods can be improved to better estimate the results of a full PRA.
