Abstract—The objective of robust design is to minimize the total quality loss in products or processes. This paper resolves the relationship between the quality loss function and the SN ratio. According to definitions of the quality loss function and SN ratio, the average SN ratio for a factor level can be transformed into a PQL value. The PQL model proposed by this study simultaneously optimizes the continuous-continuous and continuous-digital dynamic systems by minimizing the total quality loss. Using the proposed method and steps for optimization, the method addresses such problem to improve the product quality.
