Determining the optimum process mean based on asymmetric quality loss function and rectifying inspection plan

In this paper, we present a modified Pulak and Al-Sultan's model for determining the optimum process mean under the rectifying inspection plan. The perfect replacement of product is considered in the rejected lot and the asymmetric quadratic and linear quality loss functions are applied in evaluating the product quality. By solving the modified model, we can obtain the optimum process mean with the maximum expected profit per item.
