Does anyone have some ideas on any subject using the Taguchi design of experiments?

Taguchi Methods can be applied to most any system where you have controllable and uncontrollable factors (variables) and are trying to decide what parameters settings and tolerances to use. Dr. Taguchi's methods were originally applied in greater quantity to "process improvement" situations. However, now the major applications are in product and process design.

The goal is "Robust Design". That means designing the product so that it is least sensitive to uncontrollable variation during production and by the user.

Dr. Taguchi's techniques are controversial among mathematical statisticians because he violates a few of their rules and in some cases uses inefficient designs. However, he is not doing the same thing as class DOE and gets to a good design fairly efficiently. You can contact the American Supplier Institute (www.amsup.com) for some information.

(Added note: I have had the pleasure of hosting Dr. Taguchi on our campus numerous times and have had a lot of one-on-one time. He is quite brilliant and very friendly (unfortunately, his English is terrible). The impact of his work has been rather profound. Too bad we aren't teaching more about his methods in our schools.)

sir,
I would like to know details about the Taguchi Design. If you tell me some good site where I can find some material to know about this design. I am a student of Indian Statistical Institute, Calcutta. I would like to know about the topics of some small project which I can do at the level of B-Stat third year.
Thanks for the help.
pritam.

Search for the following book:
Taguchi Techniques for Quality Engineering by Philip Ross.
Can order it through www.asq.org - American Society for Quality; search under DOE books. Simplistic book to follow the Taguchi Techniques. Also provide ways to use the orthogonal arrays to improved the resolution of your DOE.

What rules does Taguchi violate and in what way are his designs inefficien but robust? Efficiency and robustnes can be defined in many different ways.
