Method of Increase of Check Efficiency Based on Small Size Samples

Abstract

In presented article is offered one more decisive rule of selective check – the equivalent operational characteristic (EOC) which is based on the Weibull distribution. Settlement formulas are given and the table of an assessment of accuracy of calculation of predicted reject by the offered technique is given. The table of the comparative analysis of accuracy of all offered before methods and the existing standard is also submitted. It is proved that use of EOC based on the Weibull distribution gives more exact (by 1,05-5,30 times) results, than use of EOC based on other distribution laws, and 2,5-8,8 times more precisely, than operating methods of boundary check on samples of small size sample.
