The Taguchi Approach
The Taguchi approach actually covers a lot more than
applying designed experiments in industry, and is in fact a complete structure
which attempts to ensure that products and processes are designed to be (i) as
close to their specified operating point as possible and (ii) robust to
external non-controllable factors which could affect the operating point.
The
particular experimental designs, and corresponding analysis tools, used by
Taghuchi have certain weaknesses and have often been heavily criticised
(although the general philosophy is accepted as being important).
Our web site will contain
further information on the Taguchi approach to industrial experimentation in the future, including
white papers on how it relates to DoE.
