The asymmetric specification limit and quality investment settings for rectifying inspection plan

Abstract

In this work, the authors propose the asymmetric specification limit and quality investment settings for the Dodge-Romig rectifying inspection plan with quality loss and product cost. This method can be used for product improvement. The optimal combination of parameters of Dodge-Romig plan with the specified consumer’s risk protection, the asymmetric specification limit coefficients of product, and quality investment are obtained by minimizing the expected total cost per unit.
