M05 - Comparison of Industrial Screening Experiment Designs

Monday, April 30
12:15 PM - 1:15 PM
Location: WSCC 611 - 612

Level: Advanced

Every quality professional has faced the problem of screening a long list of experimental variables to determine the key inputs to their process. Statisticians offer three choices for screening; fractional factorial, Plackett-Burman, and definitive screening designs. Each has its own strengths and weakness, best application, power, and run efficiency. How do you choose? This session describes the theoretical application of all three designs and compares their properties. We will then compare their performance when each was executed on the same greenhouse process in a seven-factor experiment to determine how to quickly and cheaply produce the best quality seedlings. Several manufacturing processes will be used to illustrate these designs.
