This study proposes a methodology based on multi-layer Monte Carlo simulation to model a two-stage recovery process for residential buildings, considering delay in repairs and functional downtime due to repairs. By investigating a series of policies, it aims to enhance community resilience planning through better understanding of collective communitywide impacts of these policies.
Understanding the process of community recovery impacted by various post-disaster decisions such as dynamic policies can effectively guide the recovery process and expedite recovery, thereby establishing a more resilient community. This paper proposes a methodology based on a multi-layer Monte Carlo simulation to model a twostage recovery process for residential buildings: functional downtime due to delay and functional downtime due to repair. The delay portion of the model was modified based on the REDi framework and models the impeding factors that delay repairs such as post-disaster inspection, insurance claims, and building permits. Household income was examined to estimate the financing delay depending on different funding resources such as insurance and loans available to households at different income levels. The repair portion of the model followed the FEMA P-58 approach (which was originally for post-earthquake analysis) and was controlled by fragility functions. This study also investigates a series of policies to examine an illustrative example, namely the 2011 Joplin tornado. The residential recovery is modeled as a time-stepping process without any empirical data such that policies can be implemented pre-disaster (mitigation) and/or post-disaster. The ability to model hypothetical policy scenarios for residential recovery of a community will enable decision-makers to better understand collective communitywide impacts of their actions and policies, thereby improving community resilience planning.
