The main objective of this work is to develop a comprehensive criteria-based multi-attribute decision-making model plan the rehabilitation water networks. Among features capability simultaneously analyse criteria for networks; where there significant uncertainty within operational data. In model, which called as WDSR using fuzzy TOPSIS technique, it possible adjust based on local conditions, and weight them group experts. paper, 'Anytown' network prioritised through two methods. first method...
Group Decision-Making (GDM), though could aid water companies in determining the Pipeline Rehabilitation Plans (PRPs) any network size, can impose uncertainties on PRPs due to different viewpoints of decision-makers. Thus, it should be determined when GDM ignored or considered for PRPs. To address this problem, a Fuzzy model was developed assess 10 scenarios combination with 7 size. Hence, by participating experienced experts countries, were various sizes case study. The results indicated...
Among the main concerns of water companies are to maintain optimal performance pipes in distribution networks (WDNs); this is achieved by activities, such as renewal works, maintenance actions, pressure management and other improvement operations. Accordingly, determining risk associated with useful when planning works. In study, a model developed determine pipe strategy (PRS) based on components (RCs) each pipe. Hence, comprehensive criteria relating characteristics assessed RCs. The...
Asset management of the Urban Water Infrastructure (UWI) is typically faced with limitations regarding uncertain operational data. This shortcoming can be improved using knowledge-based decisions experienced experts. However, since depend on decision-makers' knowledge and experience, verifying their results in various regions essential. subject was addressed this research. Hence, four groups experts Iran Brazil collaborated to assess criteria effective Maintenance-Rehabilitation Planning...
In this research, a hybrid risk-based decision-making (HRDM) method is proposed, in which by using pipe design parameters (PDPs), it possible to determine rehabilitation road map for water distribution networks (WDNs) the future. This can be useful that have imprecise operational-failure data when planning rehabilitation. regard, based on PDPs, supply failure risks (WSFR) of pipes network are assessed; subsequently, prioritized their potential indices (RPI), calculated model (DMM) called...

Abstract Among the most important decisions in water companies are planning Maintenance-Rehabilitation Works (MRWs) of pipelines. Since MRWs costly, it is essential to use collective an expert team for these works. However, effectiveness group not very clear and has been less considered previous studies. Hence, main objective this research assess decisions. For purpose, pipes determined based on two methods. In first, decision experts omitted, second one, considered. Finally, results...
In this study, using a hybrid knowledge-based method, the effective criteria for renovation planning of pipes are determined. The proposed method can be useful in Water Distribution Networks (WDNs) where access to data is limited. This research focused on eight WDNs Iran. Hence, by conducting evolutionary-based negotiations between 17 experts, were determined, and then ranked nominal group decision 48 operators. results indicate that lack accurate operational data, it possible determine...
Among the most important decisions water companies must make are Pipeline Rehabilitation Plans (PRPs) for Water Distribution Networks (WDNs). Such plans faced with a variety of problems in prioritizing pipes and determining their preferred rehabilitation strategies. In this regard, an expert decision-making group can aid PRPs. However, viewpoints various decision-makers may vary, leading to hesitation uncertainties process. Thus, it is know when Group Decision-Making (GDM) should be...
