Split-plot designs: What, why, and how [PDF]
The past decade has seen rapid advances in the development of new methods for the design and analysis of split-plot experiments. Unfortunately, the value of these designs for industrial experimentation has not been fully appreciated.

Split-Plot Central Composite Designs Robust to a Pair of Missing Observations
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

Evaluation of Textile Wastewater Treatment Using Combined Methods: Factor Optimization via Split Plot RSM [PDF]
The increase in the consumption of textile products as well as the use of dye compounds has increased the pollution of the effluent in these industries. Discharge of this wastewater without proper treatment can cause groundwater pollution, poisoning, and
