Услови заштите изворишта подземних вода “Јарош“ за водоснабдевање Сомбора
Ивана Јовановић (2024)Територија града Сомбор се налази у периферном северозападном делу Војводине, односно Србије, у близини границе са Хрватском. Сам град Сомбор се налази југозападном делу територије и представља гравитациони центар тог подручја. Повољан географски положај условио је афирмацију Сомбора као градског насеља, са јаком пољопривредом, индустријом, занатством и прометом. "ВОДОКАНАЛ" из Сомбора је јавно комунално предузеће чија је основна делатност захват сирове подземне воде, њен третман, и дистрибуција ка потрошачима Сомбора и приградских насеља и насељених места: Лугова, Жарковца, Чонопље, ...... caJerakoen--OMŠ 9.

The Fuzzy–AHP Synthesis Model for Energy Security Assessment of the Serbian Natural Gas Sector
Natural gas is used for the production of almost 20% of total energy today. The natural gas security of the Republic of Serbia is an urgent strategic, political and security issue. Serbia is one of the most vulnerable countries in Southeast Europe, because it only has one supply route. This study is a contribution to efforts to better understand the factors affecting energy security through the implementation of a new methodology based on the fuzzy–AHP synthesis model for measuring ...... sufficient quantities [11]. Energy security is a parameter whose specificity lies in the influence of many factors, so it is not possible to define a unique methodology to determine [12]. Defining a methodological approach for determining the energy security of a country is possible only if the geopolitical ...

Fuzzy optimization in hydrodynamic analysis of groundwater control systems: Case study of the pumping station “Bezdan 1”, Serbia
Dragoljub Bajić, Dušan Polomčić (2014)A groundwater control system was designed to lower the water table and allow the pumping sta-tion “Bezdan 1” to be built. Based on a hydrodynamic analysis that suggested three alternative solutions, mul-ticriteria optimization was applied to select the best alternative. The fuzzy analytic hierarchy process methodwas used, based on triangular fuzzy numbers. An assessment of the various factors that influenced the selec-tion of the best alternative, as well as fuzzy optimization calculations, yielded the “weights” of the alternativesand the ...groundwater lowering, groundwater management scenario, fuzzy analytic hierarchy process,expert knowledge, triangular fuzzy numbers, linguistic variables... modeling, in this case to define a groundwater control system for the “Bezdan 1” PS, is a common approach in modern hydrogeology.

Improving efficiency of thermal power plants through mine coal quality planning and control
Главни циљ контроле квалитета угља у рудницима лигнита је снабдевање термоелектрана угљем чији квалитет мора да се креће унутар одређених квалитативних ограничења. Карактеристике угља могу да утичу на ефикасност, поузданост и расположивост како котла тако и јединица за контролу емисије. У овом раду аутори су презентовали интегрисану симулацију рударског процеса као нови приступ у истраживању променљивости калоричне вредности угља приликом експлоатације комплексног лежишта лигнита.
