| Popis: | Traditional engineering can successfully define only the quality of measuring instruments and completed processes (PCI precision indices and PPI accuracy), while the quality of process results (semi-finished product, product, software, service) can only describe (good or bad quality, better or worse quality). In the modern consideration of quality, the quality of process results, today is defined by the number of decibels (dB), according to the discovery of the genius Japanese scientist Genichi Taguchi (1924 - 2012), pursuant to the Robust Technology Development Method. and standard ratio (S/N). Modern engineering considers the quality of process results, measuring instruments, and completing processes according to their quality characteristics (continuous, attributive). More often, continuous characteristics that can be more precisely defined are considered, while attribute characteristics can only be estimated. In this paper, four different types of process result quality with one attributive input variable are considered. After the calculations, the following results were achieved: in two classes with one type of error, poor quality results were obtained - 28.52, in two classes with two types of errors, the results obtained that the separation of A2 is better than A1 due to the difference of 7,532 dB, in the (S/N) ratio of the chemical reaction without side effects, the required results were obtained, in the methods of the ratio of the reaction rate of a chemical reaction with the side reactions, good quality results of 17.40 dB were obtained. |
