Model inteligentnog sistema adaptivnog upravljanja procesom prerade rude
Ivana M. Jovanović (2016-01-13)U oblasti procesa prerade rude, flotacijska koncentracija predstavlja jednu od najznačajnijih i najčešće primenjivanih metoda separacije korisnih od nekorisnih minerala. Samim tim, veoma je važno osigurati uspešan rad flotacijskog postrojenja kroz dostizanje zadovoljavajućih tehno-ekonomskih pokazatelja. Cilj upravljanja procesom flotacijske koncentracije je upravo optimizacija kvaliteta i iskorišćenja korisne komponente u koncentratu uz maksimizaciju profita. Shodno tome, istraživanja na polju modelovanja i upravljanja ovim procesom zauzimaju značajno mesto u praksi kontolnog inženjenringa.Teorijska istraživanja u okviru doktorske disertacije obuhvatila su analizu položaja ...flotacijska koncentracija, modelovanje, upravljanje, inteligentni sistem, soft kompjuting, fazi logika, veštačke neuronske mreže...

Побољшање ефикасности одлучивања у рударству применом линеарних оптимизационих модела
Трајче Бошевски (2021)Одлучивање и управљање у рударству је захтеван и сложен задатак изложен ризицима. Конвенционални-искуствени приступи доношења одлука, у пракси често показују слабост која се огледа у недовољној поузданости и прецизности. Предмет истраживања докторске дисертације, под називом „Побољшање ефикасности одлучивања у рударству применом линеарних оптимизационих модела“ је да, сагледавањем научних метода линеарног програмирања, приступи формирању локацијских модела који би били засновани на анализи и прилагођавању постојећих и увођењу нових претпоставки за случајеве као што је експлоатација и потрошња кречњака.

Ograničenja primene optimizacionih algoritama u slučaju kopova
Proces optimizacije površinskih kopova, kao sastavni deo strateškog planiranja, veoma je važan sa stanovišta ostvarivanja maksimalnih efekata proizvodnje. To je složen zadatak koji vrlo često podleže vrlo strogim geometrijskim i drugim praktičnim rudarskim ograničenjima. Ova ograničenja u posebno su izražena na površinskim kopovima uglja, te u značajnoj meri mogu povećati stepen neizvesnosti rudarskog projekta, odnosno izazvati neželjena dejstva u pogledu profitabilnosti poslovanja. Iz tog razloga, veoma je važna primena savremenih optimizacionih alata, koji u značajnoj meri mogu olakšati celokupan ......

Estimating hydraulic parameters for the complex hydrodynamic models
Hydrodynamic models have usually been calibrated manually, by trial-and-error, with different values of hydraulic parameters and hydraulic characteristics of boundary conditions. This method of calibration and estimation of hydraulic parameters requires an extensive knowledge and experience of experts, but whether the resulting solution includes an optimal set of parameters still remains an open question. An optimization method founded upon the Gauss-Marquardt-Levenberg algorithm, along with PEST software based on that algorithm, introduces automation of model calibration with regularization, which substantially ...Dušan Polomčić, Dragoljub Bajić, Jelena Ratković, Bojan Hajdin.
