Beschreibung
Within this work, a mathematical framework for the quantification of resilience of urban areas is developed. Single components of this framework allow an identification of weak spots with the statistical evaluation of multiple threats and the physical assessment of potential consequences. These risk based results are combined with time dependent recovery models to result in a resilience quantity with respect to multiple urban objects. The introduced framework allows an evaluation of different resilience phases, like prepare, prevent, protect, response and recover.
A growing urbanization, an increasing complexity of critical infrastructure and the formation of new threats are new challenges for urban areas and require a sustainable development and a stronger coping capacity with potential adverse events. Sustainability requires a strengthening of resilience.
Within this work, an integrated mathematical approach for the quantification of resilience is defined. This method allows a comprehensive evaluation of urban areas and the identification of weak spots. Statistical data are combined with physical models to assess the occurrence of multiple threats and their potential consequences. This risk based assessment is combined with time dependent recovery models to result in a quantity for resilience. Results of this framework can be applied to evaluate the effectiveness of single resilience phases, like prepare, prevent, protect, response and recover.
Besides the mathematical formulation, application examples in this work assess exemplarily terroristic threats in urban surroundings with empirical information of historical events and engineering models to assess possible structural damage effects. The comparison of different urban footprints builds the basis for a resilient urban planning process.
