PT Journal AU Javurek, M Taufer, I TI Uncertainties in Plant Optimum Definition SO Acta Mechanica Slovaca PY 2009 BP 60 EP 67 VL 13 IS 4 DI 10.2478/v10147-010-0038-9 DE technological process; optimization; uncertainty of measurement; confidence interval 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. ER
