摘要
介绍了以某食品生产商（B）对某粮食储备公司（A）生产的大米进行验收检验的过程。①当确定以平均值为质量指标的验收抽样检验时，对交付批抽取份样、制备集样及试样。②通过单次测量得到的观测值，在生产方风险α=0．05，使用方风险β=0．10，可接受质量水平μ0=15．0％，极限质量水平μ1=15．3％的条件下，计算得到批平均质量水平x=14．78；检验精度Sz=0．08及单侧规范限μ0＋1．645S／√n1=15．13。③利用格拉布斯法及常规控制图检验观测值的稳定性。④最终判断该批通过验收检验。
The process of acceptance inspection on rice between a food manufacturer （B） and a Grain Reserve Corporation （A） was introduced. ①When determined to mean values as indicators of the quality for acceptance sampling inspection, extracting sampling increment, composite sample and test sample from the batch delivery. ② By a single measurement of observed values, we calculate the number of average quality level （x = 14.78）, testing accuracy （Sx = 0.08） and one-sided specification limit （μ0 ＋ 1. 645S/√n1 = 15.13） under the conditions of the production side risks α = 0.05 ; consumer risk β= 0. 10; an acceptable level of quality μ0 = 15.0%; limit the level of quality μ1= 15.3 %. ③ To test the stability of the observed values with GRUBBS and Shewhart control charts. ④Finally, it was determined that, this batch had passed the acceptance test.
