Kapur et al. and Wen and Mergen have addressed the problems of products having specification limits but the manufacturing process not being capable of meeting the specifications in the short term. Kapur et al. report that inspection in an on-line quality control system is carried out as a short-term approach to reduce variance of the items shipped to the customers. Wen and Mergen balance the costs of products being out-of-specification by setting the optimal process mean in the short term. In this paper, we propose a modified Wen and Mergen’s cost model with a linear and quadratic asymmetrical for the measurement of the quality loss of products which are within specification, for determining the optimum process mean.
