Taguchi Approach The term Taguchi Methods refers to a collection of principles which make up the framework of a continually evolving approach to quality. This system of quality engineering takes its name (at least in the United States) from Genichi Taguchi, who along with Deming, Juran and Ishikawa, is considered a pioneer of the modern quality movement The central idea behind Taguchi’s approach to quality engineering design is that variations in a product’s performance can result in poor quality and monetary losses during the life span of the product. These variations can be classified as either controllable parameters or uncontrollable (noise) parameters. Controllable parameters are parameters that can be specified and modified by

Unformatted text preview: the designer while noise consists mainly of environmental factors and natural laws. Taguchi methods are statistical methods developed by Genichi Taguchi to improve the quality of manufactured goods, and more recently also applied to engineering, biotechnology, marketing and advertising. Professional statisticians have welcomed the goals and improvements brought about by Taguchi methods, particularly by Taguchi's development of designs for studying variation, but have criticized the inefficiency of some of Taguchi's proposals. Taguchi's work includes three principal contributions to statistics: 1-A specific loss function. 2-The philosophy of off-line quality control. 3-Innovations in the design of experiments....
