Robust design of nonlinear multiple dynamic quality characteristics
Robust design is an important method to reduce variation and to improve the performance of products or processes at low cost including static and dynamic quality characteristics. The desirability function approach is an attractive method in industry for the optimization of static multiple quality characteristics. Most of the robust design research in the literature focused on problems with static and linear dynamic quality characteristics. In this paper, we present a method to optimize the nonlinear multiple dynamic quality characteristics based on the double-exponential desirability function. The example of a temperature control circuit design is provided to demonstrate the implementation and usefulness of the proposed method. (C) 2008 Published by Elsevier Ltd.
