For the quality offset effect that cannot be described by Taguchi quality loss function, the concept of quality gain-loss function (QGLF) is presented in this paper. In considering the interaction between multiple quality characteristics, multivariate quality gain-loss function (M-QGLF) is constructed. The process mean design method of quality gain-loss is discussed under asymmetric conditions respectively. Through an example, the optimum process mean design method is analyzed under the condition of quality characteristic following skewed distribution, and the optimum process mean modified formula and deviation degree calculation formula are proposed. The presentation of QGLF creates the preconditions for the quantitative statistical analysis of quality fluctuation and quality compensation, and provides a new theoretical basis for parameter design. It will also bring great benefit to the production quality improvement as well as get significant economic effect.
