WebNov 5, 2010 · In this design, the factors are varied at two levels – low and high. Two-level designs have many advantages. Two are: The size of the experiment is much smaller than other designs. The interactions of the factors can be detected. For an example of a two-level factorial design, consider the cake-baking process. WebDesign of Experiments (DOE) is a methodology that can be effective for general problem-solving, as well as for improving or optimizing product design and manufacturing processes. Specific applications of DOE include identifying proper design dimensions and tolerances, achieving robust designs, generating predictive math models that describe ...
