dc.description.abstract | Efficiency of optimization of water networks in terms of expenditure of computer running time depends on the speed of the hydraulic calculations. In this paper use of the ΔQ method for network calculation, was tested on the example of reconstruction of distribution network in New York City. This method was used in a standard format, as well as in two modified versions. The first modification relates to the use of computed corrections ΔQ for the current situation, in the hydraulic calculation of alternative solutions within the evaluation function. The second modification involves introducing flow corrections ΔQ as additional variables, to be also a subject of optimization. In this paper genetic algorithms (GA) were used as the optimization method, which are efficient in terms of running time and finding suboptimal solutions. | en |
dc.description.abstract | Efikasnost optimizacije vodovodnih mreža u pogledu utroška računarskog vremena zavisi od brzine hidrauličkog proračuna. U ovom radu je ispitana mogućnost korišćenja ΔQ metode za proračun mreža na primeru rekonstrukcije distributivne mreže grada Njujork. Ova metoda je korišćena u standardnom obliku, kao i u dve modifikovane varijante. Prva modifikacija se odnosi na korišćenje sračunatih korekcija ΔQ za postojeće stanje, pri hidrauličkom proračunu alternativnih rešenja u evaluacionoj funkciji. Druga modifikacija podrazumeva uvođenje korekcije protoka ΔQ kao dodatne promenljive, odnosno kao veličine koja se optimizuje. U radu su kao optimizacioni metod korišćeni genetski algoritmi (GA) koji su efikasni u pogledu računarskog vremena i u pronalasku suboptimalnih rešenja. | sr |
