Abstract

The product control of process is an important problem for the manufacturer. In this paper, we present a modified Lee et al.'s model with process control model for the canning/filling industry. Assume that the surrogate variable is high correlated with the performance variable. By adopting the single-stage screening procedure of surrogate variable, we can obtain the optimum process mean and screening limits based on minimizing the expected total cost of the society. The production cost, inspection cost, rework cost, scrap cost, and the use cost of customers are included in the model. The quadratic quality loss function is used in evaluating the use cost of customers. A numerical example and sensitivity analysis of parameters are provided for illustration.
