AOKI, Akio
  Elective  2 credits
【Mechanical and Precision System・1st semester】
19-1-0206-2008

1.
Outline
The following contents will be learned.
(1) Concept of system selection, parameter design, and tolerance design in quality engineering
(2) SN ratio and Kando (sensitivity) in quality engineering
(3) Design of experiments
(4) Orthogonal array and Analysis of Variance
(5) Case study in automobiles
In this lesson, knowledge, techniques, and attitudes regarding DP 2, DP 3, DP 4, and DP 5 will be acquired.
Lessons are primarily lecture-style, but pair work will be carried out as appropriate according to the contents of the each lesson.
2.
Objectives
Students can apply the function and robust design, and the SN ratio and Kando (sensitivity) used in quality engineering. And these factors' effect diagrams and variance analysis tables to specific cases in automobiles and the like.
3.
Grading Policy
Your grade in the class will be decided on the final exam (100%). After the final exam, its contents will be explained.
4.
Textbook and Reference
Textbook:"Quality engineering at development / design stage" Quality engineering course 1 (Japan Industrial Standards Association)
5.
Requirements (Assignments)
(1) As preparations for next lesson, please check the meaning of the proper noun and the contents of the relationship shown in the contents of the lesson, and come to the class. (90 minutes)
(2) As a review, please solve exercises applied to the items instructed during the lesson, so that you can cope with works in pair as appropriate in the next lesson. (90 minutes)
