Improved WDN Design by Coupling Optimal Pipe Sizing and Isolation Valve Placement

Abstrak

This paper presents a novel methodology for the coupled optimization of pipe sizing and isolation valve placement in water distribution networks (WDNs). By employing a bi-objective genetic algorithm, the methodology searches for the best solutions in the trade-off between minimizing the average demand shortfalls caused by segment isolations and minimizing the total installation costs of pipes and valves. The optimization also incorporates a constraint that ensures the telescopic distribution property of pipe diameters, guaranteeing that the pipe diameters narrow down from source(s) to external areas. The outcomes are compared with the traditional design approach, which entails, in separate steps, the least-cost optimization for pipe sizing and the placement of isolation valves at all (N-rule) or all but one (N-1 rule) pipes connected to the generic junction.
