Paper Abstract

To reasonably improve the reliability of batch product inspection results and reduce the influence of measurement uncertainty on product qualification, the problem of product misjudgment rate in total inspection was studied, and the quantitative formula of product quality misjudgment risk was deduced. Two kinds of errors in product inspection and the conditions for producing errors are analyzed, and the calculation formula of misjudgment rate for different errors is studied. The example results show that the proposed quantitative model can comprehensively reflect the risk of misjudgment in product inspection caused by measurement uncertainty, and the quantitative data can more directly reflect the risk of both producer and consumer sides, thus prompting the inspectors to judge the qualifications more carefully.
