Since their introduction by Jones and Nachtsheim in 2011, Definitive Screening Designs (DSDs) have seen application in fields as diverse as bio-manufacturing, green energy production, medical technology, laser etching, and touch screen optimization. DSDs are small, three-level screening designs that frequently allow the experimenter to perform factor screening and subsequent response-surface optimization in a single step. Moreover, the capabilities of this new family of designs has expanded considerably in the interim. We now understand that definitive screening designs can be easily constructed from conference matrices; we know how to add two-level categorical factors; we know how to block these designs orthogonally; and an effective model selection method, that leverages the unique structure of DSDs, has been developed. In this presentation, we will review these developments and illustrate the use of the designs with several real-world applications.
Brief Bio: Christopher J. Nachtsheim is the Frank A. Donaldson Chair of Operations Management and Chair of the Supply Chain and Operations Department in the Carlson School of Management at the University of Minnesota. Dr. Nachtsheim's teaching and research interests center on the optimal design of industrial experiments, regression and predictive analytics, and quality management. Among his major publications are two texts: Applied Linear Statistical Models, 5th Edition, 2005, Richard D. Irwin, and Applied Linear Regression Models, 4th Edition, 2004, Richard D. Irwin (both with John Neter, Michael Kutner, and William Li). He is co-discoverer, along with Brad Jones (SAS Institute) of Definitive Screening Designs, and is the inventor of the coordinate exchange algorithm for constructing exact optimal experimental designs. Professor Nachtsheim has published over 60 articles in the statistics literature and he has won numerous awards for his publications. Dr. Nachtsheim is a Fellow of the American Statistical Association.
