品質工学の手法における納得性の研究 (1)

抄録

The results obtained from a quality engineering study are not always persuasive. Sometimes people are convinced by an experiment even though it failed,and sometimes they refuse to believe the results even though the gain of the S/N ratio was reproduced. A survey was therefore carried out concerning the extent to which people were persuaded by the results of studies carried out using quality engineering. Questionnaires conceming several papers that had been published in academic journals were sent out and analyzed by use of the Mahalanobis-Taguchi system to find which factors were deeply related to persuasiveness. As a result of the analysis, it became clear that the S/N-centered approach was highly persuasive. Individual differences in persuasiveness ratings were also found, and it became clear that these differences were related to a person's quality engineering career.
