In this paper, we present an economic model for selecting the most profitable initial process mean and the length of resetting cycle in a tool-wear process subject to a constant linear trend during the same cycle that varies after resetting the processes. An economic model is constructed on the basis of the costs of quality, resetting, and scrap. We assume that the quality loss function due to the deviation from the target value is asymmetric quadratic, resetting and scrap costs are constant. Assuming that the quality characteristic of interest is normally distributed, the optimum initial process mean and the length of resetting cycle are jointly obtained by minimizing the expected loss per unit time. An illustrative example is given and sensitivity analysis performed.
