Abstract

Taguchi introduced a collection of performance measures called signal-to-noise ratios (SNRs) as a core component of the robust design methods he introduced to US corporations in the 1980s. The SNR is the most controversial part of Taguchi's methods because it summarizes the quality information from the entire experiment in a single entity. While the use of a single performance measure provided a conceptual simplicity attractive to engineers, it also introduced certain statistical controversies. We review the strengths and limitations of this performance measure and the evolution of related research. Our discussion includes the use of the SNR for both static and dynamic robust design (see Robust Design).
