DOE Although many things have been learned to this point and we have made progress, but we are not quite there. Earlier in the project the team determined that thickness was the main problem relating to the high level defects in the leveler plates. The analysis has been completed. Now, we want to IMPROVE the process. You recommend using a design of experiments approach to hopefully realize a breakthrough improvement. The team brainstorms a long list of possible reasons why the thickness is not capable. From that list, the team has reduced it down to five factors they want to include in an experiment. They suspect interactions, so they conclude a full factorial will be required. They refer to the resolution matrix (found in your reading materials and in the Fractional Factorial Designs Lecture) and they find they can learn about the effects of those five factors in 32 experiments. The factors for the experiment were Depth, Temp, Pressure, R.P.M. and Time. 2. What is the resolution as shown above? (III, IV, or V, or Full) 3. Given the teams goals and budget, what is your recommendation for the final design of this experiment? BE SPECIFIC AND USE THE CORRECT DESIGN NOTATION AND/OR TERMINOLOGY!! 4. What would the new resolution be under your recommendation in #3 above? (III, IV, or V) ::: 5. In one sentence, what will the generic confounding pattern be for your final design? (Do NOT give us the design generators or alias sets!) Factor Depth Temp Pressure R.P.M. (-) 85 140 850 4400 (+) 150 155 2500 4800 III, IV, V or Full Type your SPECIFIC recommendation here and use the correct notation for the design you recommend. III, IV, or V Describe the GENERIC confounding pattern for this design resolution. HINT: We do not want the alias sets or design generators. This should be a complete sentence describing the top two effects in DOE.
