Taguchi Designs

 

The goal of the Taguchi method is to find control factor settings that generate acceptable responses despite natural environmental and process variability. In each experiment, Taguchi’s design approach employs two designs called the inner and outer array. The Taguchi experiment is the cross product of these two arrays.

• The control factors, used to tweak the process, form the inner array.

• The noise factors, associated with process or environmental variability, form the outer array.

Taguchi’s signal-to-noise ratios are functions of the observed responses over an outer array. The Taguchi platform supports all these features of the Taguchi method. You choose from inner and outer array designs, which use the traditional ...
