A fuzzy-based decision support model for effectiveness evaluation - a case study of examination of bulldozers
Effectiveness evaluation is one of the basic components of engineering asset management and maintenance engineering in general. Effectiveness is an overall concept representing a measurement of quality of service level for the analyzed engineering system. This concept contains a series of partial indicators relating to time in operation and time for maintenance activities, as well as functional properties of the system. This article describes the analysis and structuring of partial indicators, as well as the development of a model ...Miloš Tanasijević, Predrag Jovančić, Dejan Ivezić, Uglješa Bugarić, Radiša Đurić.

Predeanu, S. Pusz, J. Ribeiro, S. Rodrigues, A.K. Singh, I. Suárez-Ruiz, I. Sýkorová, N.J. Wagner, D. Životić (2020)Self-heating of coal waste is a major problem in the leading coal-producing and consuming countries, independent of the recent or past coal exploitation history. The phenomenon of self-heating is dependent on many factors such as the properties of organic matter (maceral composition and rank), moisture and pyrite content, climate effects, and storage conditions (shape of the dump or compaction of the coal waste). Once deposited, coal waste undergoes oxidation, which can lead to self- heating with the overall temperatures ...M. Misz-Kennan, J. Kus, D. Flores, C. Avila, Z. Büçkün, N. Choudhury, K.

Место и улога система даљинског грејања у стратешким плановима развоја енергетског сектора Републике Србије
Dejan Ivezić, Marija Živković (2022)Системи даљинског грејања представљају врло битан елемент енергетског система Републике Србије. Инжењерски посматрано, ради се о системима који су концептуално осмишљени у другој половини ХХ века и чије функционисање почива на коришћењу фосилних горива. Трансформација ових система, у склопу енергетске транзиције читавог енергетског система Републике Србије, претпоставља, између осталог, значајније коришћење обновљивих извора енергије у производњи топлотне енергије, смањење губитака и повећање енергетске ефикасности производње и дистрибуције енергије, дигитализацију процеса, итд.
