There is a book on this type of DOE by Box and Draper called Evolutionary Operation: A Statistical Method for Process Improvement. For less detail and more application, there have been several articles in Quality Progress that you can access. I believe you can do a article search in the ASQNet Web site. EVOP, which has been used more in the chemical industries, is a technique for doing a DOE which takes more time (weeks instead of hours) because you make process changes on a smaller scale. Your DOE has less impact on the process because the changes are smaller and the results can be more accurate because they are accumulated over a longer period of time.

Please post new questions, etc. to the New Elsmar Cove Forum.
