DOE - Advice on Definitive Screening Design vs. half or full factorial designJMP Community I was hoping you could help.
I have some questions from a DoE practitioner whose main experience so far has been half or full factorial designs but is interested in using a Definitive Screening Design for a study of 4 or 5 factors. These questions are:
- What are the advantages and limitations of the classical two-level factorial design when compared to a DSD?
- Can a definitive screening design be used to fit a model to estimate 2-factor interactions as well as main effects and quadratics for 4 or 5 factors?
- My limited training on this has indicated that DSD is mainly used to estimate main effects from a large number of factors to establish the smaller number of factors that are significant. Then perform further DOE study on these factors. Is this correct?
- A response surface design would achieve an estimate of curvature and all interactions but would require significantly more runs. Can a DSD do this with fewer runs?
Any advice on these would be massively appreciated!
Best,
