To mitigate the acute water shortage problems, water utilities are combating to find potential solutions. Water losses management in Water Supply Networks (WSNs) is amongst the prominent solutions. This work intends to develop a decision support framework to diagnose the criticality of WSNs according to an associated Water Loss Risk Index (WLRI) at pipe and zone levels. It utilized the Fuzzy Analytic Hierarchy Process (FAHP) to evaluate the influential factors that contribute to water losses. The Fuzzy Synthetic Evaluation Technique (FSET) has been utilized to assess WLRI at pipe level and Ordered Weighted Averaging (OWA) operator has been used to aggregate the individual WLRI values for each zone. The framework is extended by incorporating Monte Carlo simulation model to generate the final ranking of zones. The outcomes of this simulation showed fair stability in terms of ranking the scrutinized zones. The integration of this framework in water losses management practices and planning policies of water utilities has a large potential in improving water supply services and the performance of WSNs.

评估市政供水系统水损的综合决策框架

为了缓解严重的水资源短缺问题，自来水公司正在努力寻找潜在的解决方案。供水网络 (WSN) 中的水损失管理是突出的解决方案之一。这项工作旨在开发一个决策支持框架，以根据管道和区域级别的相关水损失风险指数 (WLRI) 诊断 WSN 的关键性。它利用模糊层次分析法 (FAHP) 来评估导致水损失的影响因素。模糊综合评估技术 (FSET) 已用于评估管道级别的 WLRI，并且已使用有序加权平均 (OWA) 算子来汇总每个区域的各个 WLRI 值。该框架通过结合蒙特卡罗模拟模型进行扩展，以生成区域的最终排名。该模拟的结果表明，在对审查区域进行排名方面具有相当的稳定性。将该框架整合到水损失管理实践和水务公司的规划政策中，在改善供水服务和 WSN 性能方面具有巨大潜力。
