Wen and Mergen (1999) addressed a method for setting the optimal process mean when a process is not capable of meeting specifications in the short term. They selected the process mean based on balancing the cost of not meeting upper and lower specification limits. However, they have neglected to consider the quality loss for a product which is within specifications in the model. In this paper, we propose a modified Wen and Mergen’s model including the quadratic quality loss for a onesided specification limit.
