  Fuzzy expert analysis of the severity of mining machinery failure cite

  Dejan V. Petrović, Miloš Tanasijević, Saša Stojadinović, Jelena Ivaz, Pavle Stojković (2020)

  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 ...

  Fuzzy Model for Risk Assessment of Machinery Failures cite

  Dejan V. Petrović, Miloš Tanasijević, Saša Stojadinović, Jelena Ivaz, Pavle Stojković (2020)

  The main goal of this research was the development of an algorithm for the implementation of negative risk parameters in a synthesis model for a risk level assessment for a specific machine used in the mining industry. Fuzzy sets and fuzzy logic theory, in combination with statistical methods, were applied to analyze the time picture state of the observed machine. Fuzzy logic is presented through fuzzy proposition and a fuzzy composition module. Using these tools, the symmetric position of the ...

  U radu su analizirani eksploatacioni učinci ugljenih sistema na površinskom kopu Tamnava–Zapadno polje. Period analize je prvih šest meseci tekuće godine. Analiza je vršena sa aspekta ostvarene proizvodnje, kvaliteta uglja, efektivnog vremena rada, kapacitetnog i vremenskog iskoršćenja i zastoja sistema. Za poređenje podataka različitih parametara koji po svojoj prirodi nisu međusobno uporedivi, u radu su korišćene metode višekriterijumskog odlučivanja.

  Eigensensitivity and structural optimization with accent on the repeated frequencies cite

  Nataša Trišović, Wei Li, Nikola Mladenović, Olivera Jeremić, Ines Grozdanović, Ana Petrović (2017)

  Sensitivity analysis is the study of changes in system response with respect to design parameters. It is being used in a variety of engineering disciplines ranging from automatic control theory to the analysis of large-scale physiological systems. Some of areas where sensitivity analysis has been applied include: development of insensitive control systems, use in gradient based mathematical programming methods and approximation of system response to change in a system parameter, assessment of design changes on system performance. Eigensensitivity analysis ...

  Analiza recesije, autokorelaciona i kroskorelaciona analiza vremenskih serija padavina i isticanja podzemnih voda karstnih vrela Krupac i Gradište (Stara planina, JI Srbija) izvršena je radi formiranja stohastičkog autoregresivno-krosregresivnog modela (ARCR) i kratkoročne prognoze dnevnih vrednosti izdašnosti. Usled postojanja heterogenosti i anizotropnosti karstne izdani veoma je komplikovano i zahtevno odrediti prostornu distribuciju podzemnih voda u okviru karstnog hidrogeološkog sistema, te je primenljivost determinističkih modela minimizirana. Stoga je upotreba stohastičkog modela u ovom slučaju svrsishodnija. Autokorelogram izdašnosti vrela Krupac pokazao je ...

  Zbog nepristupačnosti karstnih masiva i nenaseljenosti slivova karstnih vrela, često se sprovode osmatranja parametara kvaliteta i kvantiteta voda sporadično, po potrebi i to godišnje, sezonski/kvartalno, mesečno, nedeljno. Analize ovako formiranih nizova mogu dovesti do pogrešnih zaključaka, naročito kada se vrše analize ekstrema. Međutim, kada su u pitanju karstne izdanske vode, režim pojedinih parametara može biti jako uslovljen pluviografskim režimom. Najčešći su slučajevi da nakon otapanja snežnog pokrivača, zatim pri kišama jačih intenziteta ili dužih trajanja dolazi do skoro istovremenog ...
