Abstract:
Critical infrastructures (CIs) have become more and more interconnected in the recent past. Disturbances in one affect many others and consequences tend to become unpredictable due to manifold interdependencies and cascading effects. A decent amount of various stochastic models has been developed during the last years that try to capture this uncertainty. However, these models are not frequently used in practice, not to the least because many experts feel that there is a gap between theory and practice. In this article, we illustrate how to apply such a model by investigating the situation of a water provider that is part of an entire network of CIs step by step and describe the results of the analysis. While the data used is for illustration purpose only and describes the situation of a fictitious water provider, the assignments are based on several discussions with experts from the field.
