D-OPTIMAL DESIGNS FOR SPLIT-PLOT MIXTURE PROCESS VARIABLE DESIGNS OF THE STEEL SLAG EXPERIMENT
Barekeng, 2022 The nature of the steel slag concrete experiment followed a mixture process variable (MPV) design. In this study, the concrete is composed of five mixture components, cement, fine aggregate, coarse aggregate, percentage steel slag replaced the fine ...

A Split Plot Design for an Optimal Mixture Process Variable Design of a Baking Experiment
Journal of Physics, Conference Series, 2019 A mixture process variable (MPV) design consists of mixture design and process variable(s). The problem in MPV experiment is the number of experiment runs will be larger if the process variable increases.

The effect of ethanol on potato growth and production at moderate elevation
Research in Agricultural Engineering, 2022 Indonesia's current potato cultivation areas are mainly in the highlands (1 000 m above sea level - a.s.l.). However, there are obstacles to potato cultivation in the highlands, including erosion, declining land productivity, limited area, and high ...

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,
