This work proposes a multi-criteria decision analysis (MCDA) as a useful tool for supporting interventions to overcome problems faced by water utilities due to inadequate network hydraulic capacity. Urban population growth and ageing infrastructure have brought new challenges at a time of mounting preoccupations with high consumer expectations of water services. The proposed MCDA approach uses four criteria to assess the performance of a set of alternative designs for the reinforcement of existing water networks. The traditional formulations that only consider a single-phase fixed plan are replaced with a flexible and robust design approach able to deal with uncertainty related to future demand changes. For this purpose, a phased planning horizon scheme is proposed that considers various possible future demands that the network might have to cope with during its lifespan. After implementing the solution for the first phase, the reinforcements foreseen for the next phases can be reassessed if new information becomes available. The procedure can be repeated up to the last phase. This means that the infrastructure is prepared from the outset to deal with circumstances to change as time unfolds. The results for a specific case study show that the value of MCDA lies in the insightful information that it provides for decision makers.

这项工作提出了多标准决策分析（MCDA），作为支持干预措施以克服由于水力网络不足而导致水务公司面临的问题的有用工具。在人们对水服务的期望很高的时候，城市人口的增长和基础设施的老化给人们带来了新的挑战。拟议的MCDA方法使用四个标准来评估用于增强现有水网络的一组替代设计的性能。仅考虑单阶段固定计划的传统表述已被能够应对与未来需求变化相关的不确定性的灵活而强大的设计方法所取代。以此目的，提出了一个分阶段的计划范围方案，该方案考虑了网络在其使用寿命期间可能必须应对的各种可能的未来需求。在实施第一阶段的解决方案之后，如果有新的信息可用，则可以重新评估为下一阶段预见的增强功能。可以重复执行该过程，直到最后一个阶段。这意味着基础架构从一开始就准备好应对随着时间推移而发生变化的情况。特定案例研究的结果表明，MCDA的价值在于它为决策者提供的有见地的信息。这意味着基础架构从一开始就准备好应对随着时间推移而发生变化的情况。特定案例研究的结果表明，MCDA的价值在于它为决策者提供的有见地的信息。这意味着基础架构从一开始就准备好应对随着时间推移而发生变化的情况。特定案例研究的结果表明，MCDA的价值在于它为决策者提供的有见地的信息。
