Design of Experiments


 
A general overview of concepts is in the presentation file "ConcExperDesign_200801.ppt" (on this page).  This presentation covers more than just DOE, and includes other concepts such as Regression, comparison of means, types of data, and many other topics.

For a good overview of Experimental Design, see the presentation "Concepts in Experimental Design" (courtesy of T. Nichols) on this page.


Goals of a DOE study may include one or more of the following:
  • Finding the process inputs, and interactions, that most affect the process output(s) (understanding the system)
  • Finding a setting in the design space that optimizes some criteria of the process output (maximize or minimize process mean and/or process variation)
  • Finding an area of the design space where the process output is robust to changes in process inputs
