The robust design is a concept developed by Taguchi in the 1950s. It is based on the fact that a product must be reliable even unforeseen situations.
Taguchi’s plans are among the most popular in the industry and particularly in design and quality services.
The plans produced are original Taguchi. They cross the test matrices of the main factors with the noises to set up a plan of experiments which will make it possible to study the variability of the results according to these uncontrollable factors.
The loss function of Taguchi is the second part of philosophy. It makes the link between the technique and the cost of quality, allowing to define the tolerances of a system.
