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. Availability is an overall indicator and contains partial indicators that are oriented towards reliability, maintenance, and logistical support. Availability presents a variable value and changes in time and space. Usually, availability is shown as the ...... methodology, M.T. and I.J.; validation, D.I. and T.S.; formal analysis and writing—original draft preparation S.D.

Determining the Availability of Continuous Systems at Open Pits Applying Fuzzy Logic
This work presents a model for determining the availability of continuous systems at open pits by applying fuzzy logic and fuzzy inference systems. The applied model was formed by the synthesis of independent partial indicators of availability. The model is based on an expert system for assessing the availability of continuous mining systems. The availability of the system, as a complex state parameter, is decomposed into the partial indicators, reliability, and convenience of maintenance, and the fuzzy compositions, used ...системи, континуални систем експоатације, површински коп, рударство, расположивост, фази логика, max–min композиција, min–max композицијаMiljan Gomilanović, Miloš Tanasijević, Saša Stepanović.

Метода променљивих околина за решавање проблема p-центра са поузданом мрежом
У овом раду је разматран проблем p-центра са поузданом мрежом (енгл. Reliable p-center facility location problem - RpCFLP). Решавање проблема подразумева иницијално успостављање p ресурса и алокације корисника, као и накнадну реалокацију корисника у складу са новонасталим сценаријима који садрже информације о онеспособљеним ресурсима и осталим измењеним улазним подацима. За решавање посматраног проблема предложена је метахеуристика заснована на итеративној варијанти основне методе променљивих околина (енгл. Iterated basic variable neighborhood search - IBVNS). Резултати тестирања предложене метахеуристике указују на њену ...Јована Рађеновић, Стефан Мишковић, Оливера Станчић.
