Taguchi Designs

Designs with Noise Factors

A Taguchi design uses crossed array to explore factors in the presence of noise. A Taguchi design has two parts: the inner array is a design for control factors, and the outer array is a design for the noise factors. The full design is the cross product of the two arrays.

Note that noise factors in production that are not easy or cost effective to control must be controlled during an experiment. Alternatives to Taguchi designs include combined arrays and mixed resolution designs (Borror 2000). For an example of a design with noise factors using the custom designer see Experiments for Robust Process and Product Design in the Examples of Custom Designs section.
