Split-Plot Central Composite Designs Robust to a Pair of Missing Observations
Journal of Applied Sciences and Environmental Management, 2018 This study constructs robust split-plot central composite designs against missing pairs of observations. Split-plot central composite designs (CCD) consist of factorial (f), whole-plot axial (α), subplot axial (β), and center (c) points. A loss function

Improved Split-Plot and Multistratum Designs [PDF]
Technometrics, 2015 Many industrial experiments involve some factors whose levels are harder to set than others. The best way to deal with these is to plan the experiment carefully as a split-plot, or more generally a multistratum, design. Several different approaches for constructing split-plot type response surface designs have been proposed in the literature since 2001,

Split-plot designs for multistage experimentation [PDF]
Journal of Applied Statistics, 2016 ABSTRACTMost of today’s complex systems and processes involve several stages through which input or the raw material has to go before the final product is obtained. Also in many cases factors at different stages interact. Therefore, a holistic approach for experimentation that considers all stages at the same time will be more efficient. However, there
