ABSTRACT

This paper presents a multi-criteria decision support methodology for selection and prioritization of rehabilitation intervention in urban water infrastructures considering performance, cost and risk and a long-term perspective. This methodology is divided into three main stages: problem identification, structuring and evaluation. Problem structuring, a crucial stage for the outcomes, includes identifying objectives, selecting scenarios within the analysis period, defining problem options and the problematic type. Problem evaluation includes the selection of assessment metrics, selection of the aggregation method, application of the method and sensitivity and robustness analysis and final recommendations. The methodology is applied to a real case study of a water distribution system, being the different stages presented in detail and obtained results discussed.

摘要

本文提出了一种多标准决策支持方法，用于在考虑性能、成本和风险以及长期视角的情况下，选择和确定城市供水基础设施修复干预的优先级。该方法论分为三个主要阶段：问题识别、构建和评估。问题构建是结果的关键阶段，包括确定目标、在分析期内选择场景、定义问题选项和问题类型。问题评估包括评估指标的选择、聚合方法的选择、方法的应用以及敏感性和稳健性分析和最终建议。该方法应用于配水系统的真实案例研究，
