Course description and aims
【 Overview 】
In this lecture, basic theory of the Taguchi method is lectured, and in addition, a practical design technique by the Taguchi method is taught by the exercise using a paper helicopter.
【 Aim 】
It is apparent that the reliability is the most important issue for many industrial products,especially for the artificial satellites and the aerospace instruments. Assessment of reliability improvement should be conducted not only on the reliability of individual products, but also on the robustness of the whole system against the dispersion. Taguchi method is appreciated in the world as an engineering technique that takes into account the robustness of the products and reliability of the whole system.
The Taguchi method is an indispensable subject as standard acquisition technology.
Student learning outcomes
Students can define an equation of the ratio between the dynamic SN and the static SN, which is an evaluation index of dispersion. Students can make a plan of a parameter design which improves a performance and quality ( dispersion ) at the same time, and can analyze its experimental results.
Keywords
The quality engineering, the noise factor, the purpose function, the basic function, the functional evaluation, the optimization, the 2 step design
Competencies that will be developed
| ✔ Specialist skills | Intercultural skills | Communication skills | Critical thinking skills | Practical and/or problem-solving skills |
Class flow
In this lecture the way of statistical thinking, which is the basics of the Taguchi method, an experimental design, robust parameter design, and a Mahalanobis distance are lectured. Then, practices using the paper helicopters are conducted.
