Post-earthquake Restoration of Water Supply Infrastructure

摘要

This study attempts to develop a resilience-based recovery model of water supply system against earthquake events. Our objective is to sequence repairs to maximize system restoration through water delivery to critical locations or to maximize the number of served customers in the shortest time period given multiple failures. For these purposes, a computer simulation model can be helpful in examining restoration strategies in a risk-free and virtual environment under a range of possible emergency scenarios. Therefore, the goal of this study is to examine the effectiveness of key restoration strategies for emergency preparedness plans. Furthermore, it is envisioned that this simulation model can be used in conjunction with other pre-event and/or post-event loss reduction strategies for the design of robust and resilient water supply infrastructure and optimization of restoration strategies. The proposed methodology depicts the real-life restoration process thus can be used by planners, engineers, and decision makers to better serve the community.
