Determining the Optimum Manufacturing Target Based on an Asymmetric Quality Loss Function

Abstract

In 1998, Wu and Tang showed that the average quality loss of product can be decreased by shifting the manufacturing target from the design value. They assume that the quality characteristic obeys a uniform or normal distribution and adopt a quadratic asymmetric quality loss function. However, they did not consider the condition of using a linear asymmetric quality loss function in the model. In this paper, we present a modified Wu and Tang model with a uniform or triangular distribution under an asymmetric quality loss function for determining the optimum manufacturing target.
