Augment Designs

Use the Augment Design platform to add runs to an existing experimental design. Experimentation is often a sequential process and augmenting a designed experiment can help resolve ambiguities that result from a single design.

For an existing design table, the Augment Design platform constructs additional runs that optimize the overall design. You can add runs to accomplish the following objectives:

Replicate the design a specified number of times.

Add center points.

Create a foldover design.

Add axial points together with center points to transform a screening design to a response surface design.

Add space filling points to a design.

Add runs to the design in order to fit a specific model.

For more information about augmenting designs see Goos and Jones (2011).
