Design for Quality Using Response Surface Methods: An Alternative to Taguchi's Parameter Design Approach

This article presents the response surface methodology as an alternative approach to Taguchi's parameter design methods for optimizing designs for quality. The method is briefly explained, and its application is illustrated by an example of a preliminary design study of an advanced space transportation vehicle. The results indicate that the response surface methodology is a systematic and efficient approach that can help engineering managers design for quality, performance, and cost.
