Read full descriptionHide full description
The DoE Toolkit provides designer tools that allow you to generate classic experimental designs for the following methodologies: Screening: Full Factorial and Fractional Factorial Response Surface: Central Composite and Box-Behnken Mixture Orthogonal In addition, the DoE Toolkit includes an optimizer tool, which allows you to find an optimal subset of runs based on a design already generated using one of the designer tools. The DoE Toolkit allows you to augment any design by randomizing, replicating, and/or blocking. You can also add central points as well as axial points. You can control the way in which a generated design is displayed in the usual ways, by displaying factor levels as values or as factor level indices. Unique to the DoE Toolkit , you can also assign colors to factor levels and display a generated design using colors to represent factor levels. You can export any generated design to text (comma-separated value form), thereby making it easy to import your design into any spreadsheet or statistical analysis app.
