Taguchi techniques for off-line statistical process control
Χωραφά, Γεωργία Σ.
During the last few years, Western industry attempts to comprehend the techniques that the Japanese companies have been using so as to interpret the so- called “Japanese revolution” which is related to the production of high quality products with low overall cost. The benefit of exploiting these techniques was that the Japanese companies became very competitive, something that really shocked the west world companies; as a consequence, they focused on searching ways how to develop and produce themselves products of higher quality. It is quite impressive that the techniques practiced by Japanese companies, rely in fact on statistical techniques discovered by Western statisticians 50 years ago. The subject of this thesis is the presentation of techniques used for testing and optimizing the quality of manufactured products prior to manufacture, that is to say, at the design stage. These techniques are nowadays known as “Taguchi techniques for off-line statistical process control”, since pioneer work on them have been carried out by Dr. Genichi Taguchi.
