Designing dynamic stress tests for improved critical infrastructure resilience

Presentation of Tina Comes, Valentin Bertsch and Simon French at ISCRAM2013: Designing dynamic stress tests for improved critical infrastructure resilience

How to prepare our infrastructure systems against hazards that are increasingly hard to predict? How to create systems which can cope with anything that might happen? To answer these questions, we propose an approach that starts from analysing which are the most vulnerable and critical elements of critical infrastructure system. Other than standard approaches to risk management we do not start with modelling an event, but try to find out the failure of which system elements would be most harmful to investigate (a) what could cause such a failure and (b) how the consequences of such a failure could be limited.
