This study presents a cost minimization model for the design of water distribution networks. The model uses a recently developed harmony search optimization algorithm while satisfying all the design constraints. The harmony search algorithm mimics a jazz improvisation process in order to find better design solutions, in this case pipe diameters in a water distribution network. The model also in...

U radu su izrađeni modeli vodovodne i atmosferske kanalizacione mreže u naselju Sefkerin. Na osnovu potreba korisnika, hidrauličke analize formirana je vodovodna mreža. Proračun hidraulička analiza sprovedeni okviru programskog paketa EPANET. Kanalizaciona mreža trasirana zavisnosti od topografskih uslova, dok dimenzionisanje izvršeno na padavina dvogodišnjeg povratnog perioda. Hidraučilčki pro...

GIS is becoming an essential tool for utility companies, especially water companies, which have found an excellent way to manage and assess their assets. This paper presents an ArcView extension called AvEPA, which is a customized application oriented to the task of water network modeling. AvEPA is capable of simulating, analyzing and retrieving the actual network status under certain condition...

This paper presents the combination of linear Model Predictive Control (MPC) with Constraint Satisfaction Problem (CSP) for the operational control of drinking water networks. The methodology has been divided into two functional layers: First, a CSP algorithm is used to transfer non-linear pressure equations of drinking water networks (DWNs) into linear constraints, which can enclose feasible s...

A water distribution network (WDN) consists of thousands of nodes with nonlinear hydraulic behaviour, linked by thousands of interconnecting links. The inherent problem associated with cost optimisation in the design of water distribution networks is due to the nonlinear relationship between flow and head loss and availability of the discrete nature of pipe sizes. The importance and huge capita...

Abstract Water distribution networks require huge investment for construction. Involved people, especially researchers, are always seeking to find a way decreasing costs and achieving an efficient design. One of the main factors network design is selection proper diameters based on deficit flow pressure velocity in network. The reduction construction accomplished by minimizing diameter pipes wh...
