RT Journal Article SR Electronic A1 Javůrek, Milan A1 Taufer, Ivan T1 Uncertainties in Plant Optimum Definition JF Acta Mechanica Slovaca YR 2009 VO 13 IS 4 SP 60 OP 67 DO 10.2478/v10147-010-0038-9 UL https://www.actamechanica.sk/artkey/ams-200904-0008.php AB The article presents a method of simulated determination of the optimum regime in a reactor in which a competitive consecutive reaction A → B → C takes place. The algorithm of optimization method of Kiefer-Johnson is described (method with Fibonacci numbers using), and results of experimental determination of the optimum are given. Also described are the methods of determination of limit values of confidence intervals, and the confidence intervals - uncertainty of "measured" values are evaluated from experimental data. Good accordance between the experimental results and theoretical presumptions is stated.
