Optimization models for industrial process targeting

Abstract

Recently, there has been a lot of interest in the economics of quality control. One of the important issues in quality control is finding the optimal target value for a process under various inspection policies. Researchers have considered various aspects of this problem either with 100% inspection or with quality sampling plans, but none of them has considered this problem when rectifying inspection is used. We propose developing various targeting models for one machine when rectifying inspection is used, and for two machines is series under various inspection policies. We also investigate the effect of machine variance on the optimum target value. Finally, we develop a computer package to solve various targeting models in the literature.
