Information : Design of Experiment Techniques
Raytheon Missile Systems Company (RMSC) enhanced its product design and evaluation process by implementing Design of Experiment (DOE) techniques. These techniques improved the company’s efforts by employing a structured approach to organize and evaluate data.
The company uses DOE techniques to evaluate missile performance. Experiments and tests are conducted using Monte Carlo simulations. The DOE process then uses related design parameters, from these experiments and tests, to efficiently identify system variability. The process allows for the efficient identification and elimination of a missile’s variability in relation to the test or intended threat parameter. When used accordingly, DOE techniques can optimize quality, decrease development costs, and reduce product development time.
Since implementing DOE techniques, RMSC reduced its computer run times by 88% compared to other methods, and improved the quality of performance measures. The process imparts statistical relevance into resulting indices, and reduces direct labor cost by decreasing the amount of data to be evaluated. Other areas where DOE techniques could work include evaluating and selecting information systems, network systems, and other missile systems.
