An analytic approach to the relationship of axiomatic design and robust design

The relation between two axioms in axiomatic design and robust design has been discussed thoroughly, and the inherent connection is revealed which indicates that the design satisfying the above two axioms is more robust. Furthermore, for some typical statistical distribution forms of product's quality characteristic, the mathematical relationship between the information content and quality loss as well as the relationship between information content and signal-to-noise ratio has been established. The virtue of axiomatic design for improving product quality is also promoted. In the end, some practical examples are provided to demonstrate the consistency of robust design and axiomatic design.
