Mixture DOE uncovers formulations quicker

This is the second article of a series on design of experiments (DOE). It shows how to uncover "sweet spots" where multiple product specifications can be met in a most desirable way. The first publication provided tools for process breakthroughs via two-level factorial designs. 1 This follow-up article offers a simple case study that illustrates how to put rubber or plastics formulations to the test by using powerful statistical methods for mixture design and analysis.
