Abstract
In this article, the author proposes a modification of Dodge-Romig single rectifying inspection plan with average outgoing quality limit (AOQL) protection. The quality investment and inspection error are considered in the modified model. The optimal parameters of sampling inspection plan and quality investment level are simultaneously determined by minimizing the expected total cost of product under the specified AOQL value. Finally, the comparison of solution between the modified model with/without inspection error will be provided for illustration. Key words: Dodge-Romig Single Rectifying Inspection Pan, average outgoing quality limit (AOQL), quality investment, inspection error.
Highlights
Sampling inspection plan is one of the fields for statistical quality control
We usually address the preventive method for quality improvement and adopt the process control and quality design for improving product quality and satisfying the need of customer
This paper presents the effect of inspection error on the modified Dodge-Romig (1959) model
