Water distribution networks (WDNs) are the main component of industrial and urban water systems currently formed by pipes, nodes loops. In this article, a deterministic mathematical programming approach is proposed, aiming to minimize cost looped WDNs, considering known pipe lengths discrete set commercially available diameters. The optimization model constraints mass balances in nodes, energy loops hydraulic equations, such way that no additional software needed find appropriate pressure...

Abstract Water distribution networks (WDNs) are an important part of water systems and responsible for transportation from the reservoirs to demand nodes at adequate pressure velocity. In present paper, synthesis WDN is treated as optimization problem with a mixed integer nonlinear programming formulation. The objective function be minimized total network cost, considering installation energy costs, unknown flow directions, which novelty in paper. Disjunctive linearization techniques used...

Water Distribution Networks (WDN) are important systems for industrial processes and urban centers. WDN can be formed by reservoirs, pipes, nodes, loops, pumps its complete design formulated as an optimization problem. The majority of published papers in the open literature use meta-heuristics problem solution, well hydraulic simulators to calculate pressures velocities. In present study, a Mixed Integer Non-Linear Programming (MINLP) model was developed synthesis considering minimization...

Water Distribution Networks (WDN) are systems responsible for potable water transportation in urban centers and industrial installations formed by several components.WDN synthesis can be formulated as an optimization problem with Mixed Integer Non-Linear Programming (MINLP) formulation, involving the minimization of network installation cost, considering tubes length known flow directions a discrete set available diameters.However, real WDN unknown.In present paper it is proposed model...

Abstract The design of water distribution networks (WDN) can be formulated as an optimization problem. objective function, normally, is the network cost, given by installation which depends on pipe diameters and operation pumping costs associated to network, hydraulic pumps necessary in system. demand variable nodes this variability modeled a finite set scenarios generated normal distribution.
