Robust design for mass production

The major purpose of this paper is to assure quality in mass production by using improved robust design. The essential activity in quality assurance is to achieve high quality (Cpk≥1.33). The reduction of dispersion and the reduction of bias are indispensable for the achievement of this high quality. This paper discusses the way to improve the robust design based on regression analysis for high quality, low cost and high productivity. Simulative experiments and simulative manufacturing using paper helicopters are used as concrete examples, and an education program is introduced in order to explain this approach in detail.
