1 Quality Series (Sample Slides) Design of ExperimentsQuality Series(Sample Slides)
2 Outline What is Design of Experiments? Method Step 1: Model VariablesStep 2: Set Variable TargetsStep 3: Experimental PlanStep 4: TestingStep 4: AnalysisEffects, Replicates & Interactions
3 DOE Goal Overall goal: Our approach: To model a performance parameter (i.e., a physical phenomenon) as a function of design variables (i.e., things we can control about the design)Our approach:Follow the DOE methodology
4 Step 5: Analysis Determine ß coefficients Regression analysis may be used (spreadsheets)ßs can be defined in terms of the effect a variable xi has on the perf. parameter
5 Using the Effects From a response diagram point of view: Important DV Plot values of y vs. xi(-) and xi(+)Important DVDV has no effect on perf.
