Abstract: System quality and reliability are becoming increasingly more important for maintaining market place competitiveness and customer satisfaction. The objective of this paper is to demonstrate the application of the Taguchi Method as a straightforward means of improving produce quality using simulatin based prdictions of the operating life of a critical gas turbine component. The method is applied to statistically select a set of creep life simulations that will illuminate a bucket design which is least sensitive to component and operating environment variation. Implications of this method to improving turbine component quality at the design level are discussed. The results of the Taguchi Method are compared to a robust design solution found using the more time consuming, yet more accurate Response Surface Monte Carlo method. Apparent advantages and limitations of the Taguchi Method as applied to turbine component design are discussed.
