Post-earthquake restoration of water distribution network: A resilience framework

Abstract

A demand-based seismic resilience analysis framework is proposed in this paper. Four pipe recovery strategies, including random, experienced, static importance-based and dynamic importance-based strategies, are introduced and simulated using two cases to compare their effects on improving resilience level. Based on simulation analysis, the importance-based strategies perform more efficiently in improving resilience than traditional practice prioritizing pipes nearby the water factory. In addition, although the dynamic-based strategy, the best one among the four, is not globally optimal, which is verified by exhaustion and genetic algorithms, it is still a near-optimal solution due to the limited error and high computation efficiency.
