[EN-A-026] An approach for attribute- and performance-based evaluation of interdependent critical infrastructures

Notably, in engineering and behavioral sciences, the topic of resilience is being investigated broadly quantitively in technical systems like infrastructure or public transportation and qualitatively with respect to social and organizational aspects. Especially with regard to disturbances and crises in complex socio-technical systems, human operators play a pivotal role in ensuring the continuation of operations by adapting to the situation. An integrated framework for quantitative assessment as well as behavioral aspects in a socio-technical system is therefore essential to measure resilience and to compare different design approaches. The combination of quantitative and qualitative approaches is presented in this paper. In the wake of a crisis often not only the system itself is affected but also interdependent systems. The resilience of those combined systems is the subject of this conceptual paper. Two objectives are pursued. Firstly, the creation of generic resilience management guidelines which are subsequently translated into operating procedures, strategies and practices in order to support individuals, systems and organizations in the face of crisis and to validate their cross-domain applicability. The second objective of the paper is to contribute to closing the gap between formal descriptions of resilience in technical systems and the representation of the influence of the human operators. This is done by following an approach that combines serious gaming exercises of different scenarios, expert judgment and a simplified simulation of the involved systems which provides a quantitative assessment of resilience. The ongoing work described in this paper is being carried out within the scope of the DARWIN project which has received funding by Horizon 2020. Preliminary results of the project that address the creation of resilience management guidelines will be presented.
