Abstract
This paper proposes a simulation-based methodology to evaluate the resilience of infrastructure systems considering multiple intervention scenarios. The proposed methodology features probabilistic models that are used to simulate the: 1) spatiotemporal formation of hazard events, e.g., heavy rainfall causing flooding, 2) physical and functional impacts on individual infrastructure components, followed by their performance as a system, and lastly, 3) the implementation of response and restoration measures. It also features models that characterize interventions and simulate their effects on models mentioned above. The output of the simulations is a list of metrics, e.g., the reduction in direct and indirect consequences, that can be used to evaluate the effects of interventions. The proposed methodology takes into account the uncertainties related to hazard occurrence and their impact on infrastructure systems in the evaluation of interventions, which is a major advancement over existing studies that use static hazard maps. The proposed methodology is demonstrated by using it to evaluate the benefits of three candidate storm water retention basins on enhancing the resilience of a road network in Switzerland subject to heavy rainfall, flooding, and landslides. The example provides insight into the data required to conduct such a comprehensive analysis with the presented level of detail. The proposed methodology serves as a decision support tool to facilitate the assessment and hence, planning of resilience enhancing interventions.
