A MODEL FOR RELIABIILITY ANALYSIS AND CALCULATION APPLIED IN AN EXAMPLE FROM CHEMICAL INDUSTRY

The subject of this paper is reliability design in polymerization processes that occur in industrial chemical reactors. The designed model is used to determine the characteristics and indicators of reliability, which enables 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 a deductive method based on designing a scheme for fault tree analysis of a system based on inductive conclusions. It involves the use of 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 serves to obtain complete information on the probability of top event in the process, as well as objective decision making and alternative solutions.
