Method for water distribution systems reliability evaluation

Abstract

New methodology for water resources systems reliability evaluation is presented. Proposed methodology considers both: mechanical reliability (probability of pipe failure) and reliability of hydraulic parameters in nodes and links (pressure, velocity). On the base of this methodology model NETREL was developed. This model is useful for determine reliability of systems with different configurations and complexity. Also, it makes possible restriction of various hydraulic parameters and their values. Model was analyzed on different water supply systems.

U radu je prikazana nova metodologija za određivanje pouzdanosti složenih vodoprivrednih sistema, koja pored pouzdanosti mehaničkih karakteristika elemenata, uzima u obzir i pouzdanost zadovoljenja hidrauličkih parametara sistema. Ova metodologija iskorišćena je za formiranje modela NETREL, koji omogućava određivanje pouzdanosti sistema različitih konfiguracija i nivoa složenosti, sa različitim ograničenjima u pogledu hidrauličkih parametara sistema i njihovih vrednosti. Model je analiziran na primerima vodovodnih sistema.
