Split-plot designs for multistage experimentation [PDF]
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

Reducing the number of experiments in split-plot optimization designs
Two experiment reduction procedures for split-plot designs are investigated using a data set containing 160 experiments, consisting of 80 duplicate results for the optimization of a water-acetone-N,N-dimethylformamide mixture with HCl, o-dianisidine and ...

Improved Split-Plot and Multistratum Designs [PDF]
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,

Soil Carbon Characteristics of a Fluvisol Affected by Aggregates from Two Tillage and Crop Regimes
We investigated soil carbon characteristics of a Fluvisol as influenced by different ped sizes and crop types for a period of 10 years in Owerri, Southeastern Nigeria. The experimental design was a split-split plot arranged in a randomized complete block
