Abstract

ABSTRACT This paper proposes a method for prioritizing sewer cleaning operations in the absence of historical data on failures. The method utilizes the Induced Ordered Weighted Averaging (IOWA) multi-criteria decision-making technique, incorporating experts' opinions to regulate subjective inferences and ascertain uncertainty. The study considers ten parameters categorized into three main focuses: structural, environmental, and operational to analyze sewer pipe conditions. As a case study, four small zones in Tehran city were prioritized using the proposed methodology. The findings reveal that (1) decision-makers' subjective priorities and evaluations do not significantly influence critical cleaning options, (2) pipe diameter is the most effective parameter for prioritizing since it allows pipes to be meaningfully categorized and compared, and (3) slope, age, depth, upstream manhole condition, and the number of connections and laterals are more important than other parameters. Overall, this study provides valuable insights into developing effective prioritization strategies for sewer cleaning operations.

采用诱导有序加权平均和模糊逻辑相结合的方法，提出了污水管道清洁优先排序的新方法

本文提出了一种在没有故障历史数据的情况下对下水道清洁操作进行优先排序的方法。该方法采用诱导有序加权平均(IOWA)多准则决策技术，结合专家意见调节主观推理，确定不确定性。该研究考虑了10个参数，分为三个主要重点:结构、环境和操作，以分析污水管道的状况。作为一个案例研究，在德黑兰市的四个小区域优先使用拟议的方法。研究结果表明:(1)决策者的主观优先级和评价对关键清洗方案没有显著影响;(2)管径是最有效的优先级参数，因为它可以对管道进行有意义的分类和比较;(3)坡度、年龄、深度、上游沙井条件、连接和分支的数量比其他参数更重要。总的来说，这项研究为制定有效的下水道清洁优先策略提供了有价值的见解。

期刊介绍： Urban Water Journal provides a forum for the research and professional communities dealing with water systems in the urban environment, directly contributing to the furtherance of sustainable development. Particular emphasis is placed on the analysis of interrelationships and interactions between the individual water systems, urban water bodies and the wider environment. The Journal encourages the adoption of an integrated approach, and system''s thinking to solve the numerous problems associated with sustainable urban water management. Urban Water Journal focuses on the water-related infrastructure in the city: namely potable water supply, treatment and distribution; wastewater collection, treatment and management, and environmental return; storm drainage and urban flood management. Specific topics of interest include: network design, optimisation, management, operation and rehabilitation; novel treatment processes for water and wastewater, resource recovery, treatment plant design and optimisation as well as treatment plants as part of the integrated urban water system; demand management and water efficiency, water recycling and source control; stormwater management, urban flood risk quantification and management; monitoring, utilisation and management of urban water bodies including groundwater; water-sensitive planning and design (including analysis of interactions of the urban water cycle with city planning and green infrastructure); resilience of the urban water system, long term scenarios to manage uncertainty, system stress testing; data needs, smart metering and sensors, advanced data analytics for knowledge discovery, quantification and management of uncertainty, smart technologies for urban water systems; decision-support and informatic tools;...
