Koncept prediktivnog održavanja 4.0 (PdM) u energetici – konekcija sa budućom primenom Industrije 5.0
Četvrtu industrijsku revoluciju - Industrija 4.0 karakteriše upotreba cyber-fizičkih sistema. Da bi se postigla optimalna strategija održavanja (ali i proizvodnje), neophodno je razviti sisteme koji podržavaju napredne inteligentne sisteme održavanja ili tehnologije pametnog održavanja. Iz toga su proizašli postulati Prediktivnog održavanja 4.0 koji definišu veoma blisku budućnost u oblasti održavanja tehničkih sistema. Prediktivno održavanje 4.0 uključuje iskorišćenje snage veštačke inteligencije za stvaranje stalnog uvida u otkrivanje uzroka i anomalija u radu opreme, koje se ne otkrivaju kognitivnim moćima.

Correlation of uniaxial compressive strength with the dynamic elastic modulus, p –wave velocity and s –wave velocity of different rock types
Knowing mechanical properties of rocks incorporated with ultrasonic waves velocities investigations provide a secure basis for mine modelling. Uniaxial compressive strength, dynamic elastic modulus and ultrasonic waves velocities are just some of the rock properties that indicate on presence of discontinuities, stratification and fissures of rocks. Determining the relationship of these rock properties testing the rock samples that are corresponding to different rock types extracted from different mineral deposits represents the core of this study. In this paper, we ...Jelena Majstorović, Miloš Gligorić, Suzana Lutovac, Milanka Negovanović, Luka Crnogorac.

Regional rockfall exposure assessment, experience from Serbia
Rockfalls are common in hilly and mountainous areas, especially along roads with engineered slopes and cuts. Such is the case for most of the state and local road routes in Central, Serbia, which was the subject in this case study. A road network of 276 km covering roughly 1700 km2 between the cities of Kraljevo, Čačak and Ivanjica is presented. Assessing of such wide areas needs to be conducted from large to site-specific scale, i.e., using GIS spatial tools ...Miloš Marjanović, Biljana Abolmasov, Uroš Đurić, Jelka Krušić, Snežana Bogdanović.

Highway construction in fossil landslides zones – Lessons learned from the Grdelica Gorge, Serbia
Landslides are common on roads, which directly affect the flow of traffic and the connection and functioning of the population in surrounding area. Therefore, it is necessary to investigate them in the shortest possible time and to determine and carry out the remediation solution. Functionality of the state roads is immensely important so it is necessary to ensure that the traffic is maintained during remediation activities. Therefore, design solutions and remediation execution technology should be adapted to these requirements. ...Biljana Abolmasov, Marinos Skempas, Svetozar Milenković, Janko Radovanović, Miloš Marjanović.

Multi-Criteria Fuzzy-Stochastic Diffusion Model of Groundwater Control System Selection
When considering data and parameters in hydrogeology, there are often questions of uncertainty, vagueness, and imprecision in terms of the quantity of spatial distribution. To overcome such problems, certain data may be subjectively expressed in the form of expert judgment, whereby a heuristic approach and the use of fuzzy logic are required. In this way, decision-making criteria relating to an optimal groundwater control system do not always have a numerical value. Groundwater control scenarios (alternatives) are identified through hydrodynamic ...expert judgment, linguistic variables, fuzzy dynamic TOPSIS, hydrogeology, groundwater control system, open-cast mine, geometric Brownian motionDušan Polomčić, Zoran Gligorić, Dragoljub Bajić, Miloš Gligorić, Milanka Negovanović.

Primena programa UVSZ pri zaštiti od miniranja
Primena energije eksploziva tj. miniranje, predstavlja osnovni način eksploatacije čvrstih mineralnih sirovina u rudarstvu. Miniranjem se postižu vrlo povoljni tehnoekonomski pokazatelji, koje nažalost prate i negativni efekti miniranja. U cilju zaštite životne sredine potrebno je za svaku radnu sredinu odrediti jednačinu oscilovanja stenske mase pri miniranju. Ova jednačina definiše promenu brzine oscilovanja stenske mase u zavisnosti od rastojanja, količine eksploziva, uslova izvođenja miniranja i geoloških karakteristika stenske... zaštiti od miniranja Suzana Lutovac, Miloš Gligorić, Jelena Majstorović, Luka Crnogorac, Rade Tokalić Дигитални репозиторијум Рударско-геолошког факултета Универзитета у Београду [ДР РГФ] Primena programa UVSZ pri zaštiti od miniranja | Suzana Lutovac, Miloš Gligorić, Jelena Majstorović, Luka Crnogorac ...

The ‘Umka’ landslide
We present an in-depth landslide map of the ‘Umka’ landslide near Belgrade, Serbia, at a scale of 1:5000. The map delineates elements at risk, primarily buildings and road infrastructure impacted by the landslide displacements of several cm per year, introduced during frequent reactivation stages. The Main map results from a survey of over 350 buildings and more than 7 km of state and local roads. The acquisition techniques included engineering geological field mapping, building survey, and visual interpretation of ...rizik od klizišta, elementi rizika, kartiranje pomoću drona, ispitivanje objekata, geotehnički monitoring"Uroš Đurić, Dragana Đurić, Miloš Marjanović, Biljana Abolmasov, Ivana Vasiljević.

Selection of Artificial Lift Methods: A Brief Review and New Model Based on Fuzzy Logic
Miroslav Crnogorac, Miloš Tanasijević, Dušan Danilović, Vesna Karović Maričić, Branko Leković (2020)Artificial lift methods have applications in oil wells where oil production is no longer possible due to natural reservoir energy, so this necessary energy is added by introducing lift methods. In order to achieve optimum production, the selection of an artificial lift method is very important. This paper uses fuzzy logic as a mathematical and conceptual model for selection of the optimal artificial lift method. The outcome or IF-THEN rules, as the central part of the model, is based ......

Fuzzy expert analysis of the severity of mining machinery failure
Mining machinery failure is almost an everyday occurrence. Usually the failures bare certain consequences, which require additional financial costs to repair and restore the system to its operational state. The consequences are viewed through negative and damaging effects a failure has on the machine, health and safety of the employees, work environment, and on the environment. The removal of the consequences of the failure requires additional financial investment, which has a negative impact on the company’s business. In order ...Dejan V.
