SIMULTANEOUS OPTIMIZATION OF THREE FACTORS RELATING TO QUALITY USING TAGUCHI EXPERIENCES PLANS

Anton Marius POPA

Abstract


For optimizing certain tehnological factors, characteristics, for a producs or a proces, there are several tehniques available, some of them take account of the factors that might produce errors, imbalances and other tehniques will not. For a product or process that is kept  well under control, the external factors that are capable of generating errors are removed, asuring a better stability and control. In the case of dispersion or instability of a product while it is constructed or used, the methods most often used try to diminish or eliminate the errors that are taken into account. The Taguchi strategy, will try to minimize the impact of the parasitic effects (also called noise factors), rather than elimination them, by combining the defined levels set at the beginning for the measured factors. The factors chosen in a test, depends on the criteria which are to be implemented and will be chosen by specialists in the certain field, experts that know the process.
