Abstract

Despite the increasing attention on urban flood control measures (UFCM) for urban drainage systems (UDS), current approaches often overlook the spatial variation in urban flood resilience (UFR) and trade-offs across multiple decision-making levels. To address these challenges, this paper develops a bilevel multi-objective optimization (BMOO) model for large-scale UFCM, aiming at an optimal trade-off of public safety, sustainability, and efficiency. The results show that the model can effectively address the diverse objectives of two decision-making levels. The bilevel model can reduce the risk of surface overflows risk and improve the resilience of the UDS compared to the initial scheme while saving 39.8 % of the travel distance. In general, this paper presents a bilevel approach to solve simultaneously a multi-objective and multi-level decision-making problem in large-scale UFCM, providing an optimized solution for regional-level spatial prioritization, component-level critical segments identification, and route planning in UDS maintenance activity.

大型城市排水系统防洪措施的双层规划方法

尽管人们越来越关注城市排水系统（UDS）的城市防洪措施（UFCM），但目前的方法往往忽视了城市洪水恢复力（UFR）的空间变化以及多个决策层面的权衡。为了解决这些挑战，本文开发了大型UFCM的双层多目标优化（BMOO）模型，旨在实现公共安全、可持续性和效率的最佳权衡。结果表明，该模型能够有效地解决两个决策层次的不同目标。与初始方案相比，双层方案可降低地面溢流风险，提高UDS系统的弹性，同时可节省39.8%的行程。总体而言，本文提出了一种双层方法，同时解决了大规模UFCM中的多目标多层次决策问题，为UDS维护活动中的区域级空间优先级、组件级关键段识别和路线规划提供了优化解决方案。
