Information : Engineering Design of Experiments
Litton Guidance and Control Systems Division (GCSD) extensively uses design of experiments (DOE) in production to reduce product variability, and in manufacturing process design to reduce wear/deterioration rates and process variations. DOE is also incorporated in product design to reduce product design sensitivity to environmental variations.
The first step in the DOE process is to perform a basic design evaluation to identify deficiencies. A team of experts representing all disciplines is assembled to brainstorm possible solutions to the problems. The critical factors are assembled in an appropriately sized Taguchi array and desired result measurement criteria are developed. Factor levels are determined, and hardware is built and analyzed. The predicted best configuration is then identified, built and validated.
Over 70 engineers have been trained in the use of DOE. The DOE techniques work as well in Engineering Design as they do in manufacturing processes. Using these techniques in engineering has reduced the required time to achieve desired performance with reduced product variability and sensitivity.
