“This is an engaging and informative book on the modern practice of experimental design. The authors’ writing style is entertaining, the consulting dialogues are delightful, and the technical material is presented brilliantly but not overwhelmingly. The book is a joy to read. Everyone who practices or teaches DOE should read this book.” – Douglas C. Montgomery, Regents Professor, Department of Industrial Engineering, Arizona State University.
“It’s been said: ‘Design for the experiment, don’t experiment for the design.’ This book ably demonstrates this notion by showing how tailor-made, optimal designs can effectively meet a client’s actual needs. It should be required reading for anyone interested in using the design of experiments in industrial settings.”
—Christopher J. Nachtsheim, Frank A Donaldson Chair in Operations Management, Carlson School of Management, University of Minnesota
This book demonstrates the utility of the computer-aided optimal design approach using real industrial examples. These examples address questions such as the following:
- How can I do screening inexpensively if I have dozens of factors to investigate?
- What can I do if I have day-to-day variability and only perform three runs a day?
- How can I do RSM cost effectively if I have categorical factors?
- How can I design and analyze experiments when a factor can only be changed a few times over the study?
- How can I include both ingredients in a mixture and processing factors in the same study?
- How can I design an experiment if many factor combinations are impossible to run?
- How can I make sure that a time trend due to the warming up of equipment does not affect the conclusions from a study?
- How can I consider batch information when designing experiments involving multiple batches?
- How can I add runs to a botched experiment to resolve ambiguities?
While answering these questions, the book also shows how to evaluate and compare designs. This allows researchers to make sensible trade-offs between the cost of experimentation and the amount of information they obtain.
