Abstract
Obravnavana je izbira merilnih mest za umerjanje hidravličnih modelov vodovodnih sistemov. Izbira merilnih mest za umerjanje hidravličnih modelov je podana kot optimizacijski problem, ki je sestavljen iz dveh normaliziranih ciljnih funkcij. S prvo ciljno funkcijo se povečuje natančnost umerjanja parametrov hidravličnega modela, z drugo pa zmanjšuje število potrebnih merilnih mest. Predstavljeno je reševanje optimizacijskega problema z uporabo genetskih algoritmov. Overitev in uporaba razvitega optimizacijskega modela (imenovan IMMe) je bila opravljena na hidravličnem modelu teoretičnega vodovodnega sistema "Anytown", ki je namenjen kot primerjalni model za testiranje različnih raziskav pri hidravličnem modeliranju. Overjeni model IMMe je bil uporabljen na stvarnem vodovodnem sistemu mesta Sežane. Uporaba genetskih algoritmov se je v obeh primerih izkazala za zelo učinkovito optimizacijsko orodje pri izjemno kombinatornih optimizacijskih problemih. Razvita modela umerjanja in izbire merilnih mest omogočata vzpostavitev kar se da natančnih hidravličnih modelov vodovodnih sistemov, ki bodo v prihodnosti ključnega pomena za zagotavljanje gospodarnosti in učinkovitosti oskrbe s pitno vodo.

Title:Sampling design for water distribution system models by genetic algorithms
Abstract:
In this paper we discuss sampling design for the calibration of water distribution system hydraulic models. The sampling design for the calibration of water distribution-system models is formulated as an optimisation problem consisting of two normalised objective functions. The first objective function is used to increase the calibration accuracy of the model parameters, and the second one is used to reduce the number of necessary measurement locations. The optimisation problem was solved by using genetic algorithms. The verification and application of the developed optimisation model (called IMMe) were carried out on the artificial water distribution system of Anytown, which serves as a reference model for testing various researches in hydraulic modelling. The verified IMMe model was applied to a real water-distribution system in the town of Sezana. For both water distribution models, the use of genetic algorithms proved very efficient with extremely combinatorial optimisation problems. The developed calibration and sampling design allow very accurate hydraulic modelling of the water distribution systems, which is of key importance for ensuring the economy and efficiency of drinking-water supplies in the future.

Keywords:hydraulic, water distribution systems, modelling, optimisation, measurement locations, genetic algorithms
