As the existing quality gain-loss function is not able to solve the boundless problem in engineering practice, an inverted normal quality gain-loss function is proposed. This function is based on the characteristics of inverted normal function. Considering the variable situation of the quality compensation, the hyperbolic tangent compensation quality gain-loss function is established, and in which a quality gain-loss function with larger-the-better characteristic and smaller-the-better characteristic is designed. In view of the interaction between the characteristics of product quality, a multivariate quality gain-loss function model is also established. Through empirical analysis, the gain-loss function model is proved to be feasible.
