Deploying DOE to Predict and Improve Process Performance

November 4, 2020 from 12:45 pm to 1:45 pm

Speaker: Shari Kraber

Design of experiments (DOE) is a tried-and-true, multifactor quality tool for identifying key process drivers. This presentation demonstrates how to deploy DOE to create reliable prediction models. Case studies from a variety of industries demonstrate how to construct these models and then use them for determining more desirable process settings.

Although DOE tools require a high level of stats and math, modern-day software bears the burden of the computations. Therefore, the focus of this talk will be kept to the need-to-know elements for successful experiment design, analysis, modeling and optimization. Ultimately, effective application of DOE produces very useful predictive models that lead to profound process understanding. These models enable manufacturers to build higher-quality products at lower overall cost.

This talk presents key strategies to build DOEs that are aimed at prediction—not simply to detect effects. It lays out response surface methods (RSM) geared for most accurate and precise model generation. Participants will be briefed on the key statistics that quantify the ability of the model to make good predictions, as well as tools for final optimization. The presentation concludes with helpful tips on choosing the right DOE for the problem at hand.
