IE 466: Concurrent EngineeringT. W. Taguchi s Robust Design MethodSince 1960, Taguchi methods have been used for improving the quality of Japaneseproducts with great success. During the 1980 s, many companies finally realized that the oldmethods for ensuring quality were not competitive with the Japanese methods . The old methodsfor quality assurance relied heavily upon inspecting products as they rolled off the productionline and rejecting those products that did not fall within a certain acceptance range. However,Taguchi was quick to point out that no amount of inspection can improve a product; quality mustbe designed into a product from the start. It is only recently that companies in the United Statesand Europe began adopting Taguchi s Robust Design approaches in an effort to improve productquality and Design is Robust Design ?
quality and design robustness. What is robust design? Robust design is an “engineering methodology for improving productivity during research and development so that high-quality products can be produced quickly and at low cost” (Phadke, 1989). The idea behind robust design is to improve the quality
