“…This method is particularly suitable for solving double -objective optimization problems , but when solving optimization problems with more than three objectives , the individuals selected by the crowding distance ranking are not uniformly distributed on the non -dominated level and easily fall int o local optimality, affecting the convergence and diversity of the algorithm (Li et al, 2019). The NSGA-III algorithm introduces the concept of uniformly distributed reference points by extending the NSGA -II selection method and uses a predefined multiobjective search method that can effectively overcome the problems of non-dominated solutions , invalid crossover, and variation and provides good convergence and diversity solutions in high -dimensional cases (Sharma et al, 2022a ). The number of objective functions in this model is six, which is a high -dimensional multi -objective optimization , so the NSGA-III algorithm is used as a tool for encoding and optimization.…”

“…Leakage is the main cause of water loss in WDNs and raises potential environmental and health risks in addition to huge economic losses (Puust et al, 2010 ). However, dividing WDNs into district metered areas (DMAs) has proven effective in reducing leakage (Morrison et al, 2007 ;Sharma et al, 2022a ). DMAs are achieved by installing valves (or disconnecting pipe s) on some pipes and adding flow meters to form several discrete areas and by monitoring the amount of water entering and leaving each area and analyzing the flow to quantify leakage levels, based on which water utilities can accurately determine where leakage occurs and carry out timely repai r work (Morrison et al, 2007 ).…”

Leakage and energy consumption in urban water distribution networks (WDNs) have been receiving increasing attention, and pressure management based on district metered areas (DMAs) can effectively control leakage and save energy. In this paper, a new design method for establishing DMAs and carrying out pressure management is proposed. First, the combination of the non-dominated sorting genetic algorithm (NSGA-III) and spectral clustering algorithms, considering the partition cost, operation and management difficulty, post-partition water quality safety, and network water supply capacity factors, identifies the best DMA layouts and the corresponding boundary pipes with the help of multicriteria decision making (MCDM) methods. Second, the non-dominated sorting genetic algorithm (NSGA-II) is used to solve the optimal arrangement model of valves and flow meters on the boundary pipes, and the optimal arrangement is determined based on the equipment cost, water quality safety, and leakage control effect after partition. Finally, pressure reducing valves (PRVs) are installed at the inlet of the DMAs, and a genetic algorithm is used to solve the joint scheduling optimization model of the PRVs and pump station in WDNs to determine the optimal scheduling strategy for the PRVs and the fixed and variable speed pumps for leakage control and energy saving. The proposed method is applied to the SH town network. Results reveal that the method can establish DMAs considering multiple objectives. Furthermore, pressure management in DMAs can not only significantly reduce leakage and energy consumption of pumping stations but also improve the water quality of networks. Therefore, this method can provide a reference for water utilities in establishing DMAs and carrying out pressure management in WDNs in the future.

“…A widely adopted metric in the context of WDN partitioning ( [9][10][11]) is modularity [12], which effectively quantifies the goodness of network subdivision into communities (in terms of balanced cluster sizes and few boundary links). In this regard, the recently developed modularity-based procedure by Creaco et al 2023 [13], originally conceived for a dual WDN topology (segment/valve graphs), can be used for the clustering of the standard node/pipe topology.…”

This paper presents the partitioning of the closed water distribution network (WDN) serving the city of Pavia, Italy. As a thus far poorly explored aspect in the scientific literature, clustering for the definition of size and extension of district metered areas (DMAs) and of inter-DMA boundary pipes is performed by ensuring that the DMAs respect the altimetric areas of the WDN by leaning on a modified formulation of modularity. To define the boundary pipes to be closed or alternatively fitted with a flow meter for the monitoring of DMA consumption, the dividing is performed with an innovative heuristic algorithm. This technique operates by sequentially implementing the boundary closures that do not cause significant head losses, to obtain an approximation of the Pareto front in the trade-off between number of flow meters installed and WDN reliability. In the last part of the work, the pumps present in the network are assumed to be equipped with the variable speed drive, and their hourly settings are optimized to regulate service pressure. Overall, WDN partitioning and pump setting optimization are proven to mitigate the service pressure and energy consumption of the WDN, offering evident and attractive benefits up to about 50% for water utilities.
