Process Setting Models for the Minimization of Costs Defectives
Abstract
The economy of production controls all manufacturing activities. In the engineering component manufacture; limits are always specified, either one-sided or two-sided. This paper attempts to determine the mean setting so as to minimise the total loss through under-limit complaints and loss of sales and goodwill as well as over-limit losses through excess materials and rework costs.
Models are developed for the two types of setting of the mean so that the minimum costs of losses are achieved. Also, a model is developed for inspection frequency sample size and discovery of defective products which result in minimum cost.
