Optimization of Correlated Multiple Response Surfaces with Stochastic Covariate

Taha Hossein Hejazi, Ali Salmasnia, and Mahdi Bastan

Abstract—Optimizing quality engineering problems has become a common problem when there are several correlated product quality characteristics. Moreover, in design of experiments, controlling covariate effects could reduce error and uncovered variances as well as give more insight about the process. This work identifies process variables to analyze correlated multiple responses with stochastic covariates. It also considers dispersion effects and specification limits besides location effects in an integrated framework based on desirability function. At the end, efficacies of the proposed approach are assessed by a numerical example.

Index Terms—Design of experiments, multiresponse optimization, covariate effects, principal component analysis, and desirability function.
