Comparison of the central composite design with augmented alternative designs for response surface exploration

YEAR: 2018


The cardinal objective of response surface methodology is reliability and quality improvement through well designed experiments. The choice of response surface design that satisfies this objective has been the subject of many studies on response surface explorations. The standard central composite design (CCD) remains popular choice among practitioners but offers high number of experimental runs with increase in number of factors. In this study, we propose augmented Minimum-run resolution V CCDs (MinResV CCD) as useful alternatives to the standard CCD in response surface exploration. The standard CCD and the augmented MinResV CCD are evaluated and compared with some alphabetic and graphical criteria in spherical and cuboidal design regions. Some augmented versions of the MinResV CCDs displayed better potentials for quality improvement and with smaller design runs in most cases than the standard CCD.
