Development of Integrated Fuzzy Model for Mine Management Optimization
Miodrag Čelebić, Sanja Bajić, Dragoljub Bajić, Dejan Stevanović, Duško Torbica, Vladimir Malbašić (2023)Technoeconomic, environmental and safety criteria generally affect the management of metallic and non-metallic mining operations. The first basic question that needs to be addressed when planning ore mining is which methods are adequate and what is the optimal mining technology? Due to the complex geologic framework of ore deposits, geological exploration has rendered synonymous the inherent uncertainties, vagueness, and inaccuracies. As a result, subjective evaluation by engineers and expert experience have become increasingly important. Given that the natural language ...Miodrag Čelebić, Sanja Bajić, Dragoljub Bajić, Dejan Stevanović, Duško Torbica, Vladimir Malbašić.

Development of the Availability Concept by Using Fuzzy Theory with AHP Correction, a Case Study: Bulldozers in the Open-Pit Lignite Mine
Stevan Đenadić, Dragan Ignjatović, Miloš Tanasijević, Uglješa Bugarić, Ivan Janković, Tomislav Šubaranović (2019)Availability is one of the most used terms in maintainability engineering. This concept is used to denote: The quality of service of an engineering system, i.e., machines, weak points’ analysis, asset management, as well as making decisions in the process of life cycle management.

A multi-criteria approach for assessing the potential of renewable energy sources for electricity generation: Case Serbia
When assessing the potential of renewable energy alternatives for electricity generation, it is necessary to implement a multi-perspective approach that includes economic, technical, environmental, and socio-political criteria. For the evaluation of criteria and alternatives, the Fuzzy Analytical Hierarchy Process (FAHP) method is applied. The obtained weights are formed according to the values of energy indicators and expert judgments. The use of a fuzzy numerical value scale for the assessment of expert judgments and energy indicators provides a more sensitive ...... 12:19:33 A multi-criteria approach for assessing the potential of renewable energy sources for electricity generation: Case Serbia Boban Pavlović, Dejan Ivezić, Marija Živković Дигитални репозиторијум Рударско-геолошког факултета Универзитета у Београду [ДР РГФ] A multi-criteria approach for ...

Assessing Criteria Weights by the Symmetry Point of Criterion (Novel SPC Method) - Application in the Efficiency Evaluation of the Mineral Deposit Multi-Criteria Partitioning Algorithm
Information about the relative importance of each criterion or the weights of criteria can have a significant influence on the ultimate rank of alternatives. Accordingly, assessing the weights of criteria is a very important task in solving multi-criteria decision-making problems. Three methods are commonly used for assessing the weights of criteria: objective, subjective, and integrated methods. In this study, an objective approach is proposed to assess the weights of criteria, called SPC method (Symmetry Point of Criterion).

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.
