Robust design methods are becoming widely adopted in automotive industries because of their cost- and time-efficiency for quality improvement in a vehicle development process. These methods were pioneered by Dr. Genichi Taguchi of Japan and introduced to the U.S. in 80’s. Typical Taguchi-class robust design approaches apply S/N ratios of various types to measure the robustness performance of the output responses of target systems. Next designed experiments are applied to identify key control factors and interactions to maximize the selected S/N ratio in order to make the systems insensitive to pre-selected noise factors.
