9. Orthogonal Expansion for Tolerance Design

Abstract

Tolerance Design needs to know the magnitude of contribution of each noise variables on the output response. As the most effective way to obtain those magnitude of contribution, the use of an orthogonal array is explained in this article. The methods here have been applied for both cases, the case where we have mathematical model and the other where we have to conduct an experiments as we have no mathematical model.
