Resumen de Follow-Up Designs to Resolve Confounding in Split-Plot Experiments
Ashraf A. Almimi, Murat Kulahci, Douglas C. Montgomery
Split-plot designs are used effectively in industry, but some of the results of fractional-factorial split-plot experiments can be ambiguous and require follow-up experiments to separate effects of potential interest by breaking their alias links with others. In order to avoid the expense and difficulties associated with whole-plot factors, this study uses the foldover technique on only one or more subplot factors in order to de-alias certain effects. Six rules are provided to develop foldovers for minimum aberration resolution III and resolution IV fractional factorial split-plot designs.
