Modern DOE for Process Optimization

January 28-30, San Diego, CA

Response Surface

Updated for DX12. Via real-world case studies, this 3-day workshop lays out tools for mixture design that vary product recipes in search of the "sweet spot" where it meets all specifications. Learn the secrets for applying a multicomponent formulation strategy to maximize mixture performance. We top it all off by combining process factors, so by class-end you can literally mix your cake and bake it too.

How Design of Experiments Can Improve Formulation Development

By Greg on Nov. 11, 2019

This article from our backlist written by Jerry Fireman was published in the February 2018 CoatingsTech.

This article show how statistically-based design of experiments (DOE) provides validated models, including any significant interactions, that make it possible to confidently predict response measures as a function of the inputs.

Experimental Design in Chemistry: A Review of Pitfalls (Guest Post by James Cawse)

By James Cawse on Nov. 11, 2019

Getting the best information from chemical experimentation using design of experiments (DOE) is a concept that has been around for decades, although it is still painfully underused in chemistry. See how James Cawse suggests using DOE in chemical environments, without falling into a pitfall.

Practical Considerations in the Design and Analysis of Experiments with Binary Data

By Greg on Nov. 8, 2019

In our most recent recorded webinar, Martin Bezener, Stat-Ease Consultant, introduces Design-Expert v12’s new tools for logistic regression. After providing a primer on the statistical aspects, he lays out real-life examples that benefit from specialized modeling for binary responses. DOE level: Intermediate.
