As the funcional formula used in simulation analysis does not include noise variables arisen at various cutomer's usage conditions, the variations around the level of all design parameters are used to represent noise effects for signal to noise ratio calculation.
Because of the robustness against all those noises variables, it would be robust against all customer's usage conditions including deterioration and wear as those affect design parameters.
That is the most important strategy in robust design presented at 8th ASI Taguchi Symposium in 1990 presented by OKI Electric Co. ltd.
This paper's object is to improve the measure SNR by introducing a new measure called standard SNR. The SNR uses output data of signal at normal condition as signal values instead of signall Level itself. The new method is illustrated by the OKI case study. The new method also applicable for hardware experimentcase.
