Unformatted text preview: I ntroduction to Experimental Design Aug. 20, 2007 Outline • Traditional approach to determine an optimal process parameter • Basic ideas of experimental design • Statistical background • Types of experimental design • A simple example – RI E • Design procedure and data analysis (with interactive examples) – A screening experiment – A response surface experiment • Free resources • Summary Am I using the optimum parameters? • Experiment example: chemical synthesis • Called a One-Factor- At-a-Time (OFAT) or Change-One- Separate-factor-at-a- Time (COST) strategy. • Disadvantages: – may lead to suboptimal settings – requires too many runs to obtain good coverage of experimental http://www.acc.umu.se /~tnkjtg/chemometrics /editorial/aug2002.pdf What do I do instead - Modern approach: DoE • DoE = Design of Experiments (DoE) • Design of experiments is the methodology of how to conduct and plan experiments in order to extract the maximum amount of information in the fewest number of runs. • Key ideas: – change several factors simultaneously – use statistical analysis (Regression, ANOVA, with residual analysis, etc.) – Obtain effect estimates; response surface; global optimum region – Control and predict...
