Abstract
The subject of the paper is reliability design in polymerization processes that occur in reactors of a chemical industry. The designed model is used to determine the characteristics and indicators of reliability, which enabled the determination of basic factors that result in a poor development of a process. This would reduce the anticipated losses through the ability to control them, as well as enabling the improvement of the quality of production, which is the major goal of the paper. The reliability analysis and calculation uses the deductive method based on designing of a scheme for fault tree analysis of a system based on inductive conclusions. It involves the use standard logical symbols and rules of Boolean algebra and mathematical logic. The paper eventually gives the results of the work in the form of quantitative and qualitative reliability analysis of the observed process, which served to obtain complete information on the probability of top event in the process, as well as objective decision making and alternative solutions.

Summary
JEDAN MODEL ZA ANALIZU I PRORAČUN POUZDANOSTI PRIMENJEN NA PRIMERU IZ HEMIJSKE INDUSTRIJE. Određene su karakteristike i pokazatelji pouzdanosti, a time i utvrđeni osnovni faktora koji doprinose lošem odvijanju procesa. Failure) tehničkih sistema i njihovih sastavnih elemenata. Analiza pouzdanosti podrazumeva analiziranje otkaza tehničkih sistema i sastavnih elemenata, kao i svih činilaca koji na određeni način utiču na njihovu pojavu [5,6]. S ciljem omogućavanja analize, u teoriji pouzdanosti se posebno analiziraju načini povezivanja elemenata sistema sa stanovišta oblikovanja šeme stabla otkaza, na osnovu koje treba izvesti analitičke izraze za izračunavanje pouzdanosti sistema [5,7,8]. Osnovni cilj rada je da se kroz razvijeni model pouzdanosti utvrde osnovni faktori koji doprinose lošem odvijanju procesa polimerizacije u reaktorima posmatrane hemijske industrije.
