Abstract

Vining and Myers adapted the dual response approach to achieve the goals of Taguchi's philosophy. This excellent approach contains some deficiencies that will be highlighted in this paper. A more satisfactory and substantially simpler optimization procedure on a dual response approach is proposed that allows more general response models to be entertained in reality. The new method is demonstrated using the example given in Vining and Myers in which it leads to a solution with 25% smaller mean square error.
