Dual Response Surface Methodology is a powerful tool for simultaneously optimizing the mean and the variance of a quality characteristic in the field of quality engineering. The optimization of dual response systems to achieve better quality has played a major role in the design of industrial products and processes. In this paper we suggest using a process capability index - Cpk - as the objective function. We show by ways of multiple examples that this method improves the obtained yield of a process for different response variable types.
