The Taguchi robust design method traditionally deals with single-characteristic problems. Various methods have been developed for extending the Taguchi single-characteristic robust design method to the case of multi-characteristic robust design problems. However, most of those methods have shortcomings in that they do not properly consider the variance-covariance structures among performance characteristics and/or do not preserve the original properties of the Taguchi signal-to-noise ratio for single-characteristic robust design problems. To overcome these shortcomings, this paper develops a multivariate loss function approach to multi-characteristic robust design problems with an appropriately defined signal-to-noise ratio. Its performance is evaluated using simulated examples, and the results indicate that it generally outperforms existing representative methods for correlated as well as uncorrelated experimental data.
