Robust Design (RD) method uses a collection of mathematical and statistical tools to study a large number of variables in the process with a minimum value of computational cost. Robust design method tries to make high-quality products according to customers’ viewpoints with an acceptable profit margin.
The Taguchi Method was named after Dr. Genichi Taguchi and is also labeled as the Robust Design technique. Robust Design centers on improving engineering productivity. It is focused on the improvement of the significant function or role of a process or a product itself, therefore smoothing the progress of strategies and coexisting engineering. The Taguchi (Robust Design) approach rooted on a so called Energy Transformation method for engineering systems like electrical, chemical, mechanical and the like. It is a unique method which makes use of the ideal function of a process or product in contrast to the conventional approaches which mainly concentrate on “symptom analysis” as a source for development or improvement towards the achievement of Robustness and Quality Assurance.
