INCREASING THE RELIABILITY OF THE ACCEPTANCE SAMPLING PROCEDURES OF VVER FUEL PELLETS BY IMPLEMENTING GROUP QUALITY INDICATORS FOR CERTAIN CONTROLLED PARAMETERS
The paper discusses the special aspects of implementation for the statistical methods and plans for the acceptance sampling based on group quality indicators. The proposed method is based on the estimation of group (statistical) quality indicators: the center of distribution (average value) of the qualitative parameter relative to its tolerances, as well as the measure of variation of the data set (standard deviation). The limits for standard deviation may vary depending on the quality margin of a particular product lot. The developed control scheme proposes more flexible criteria for quality assessment in comparison with acceptance sampling by variables.
