关于计数验收抽样检查中的平均检验件数问题

Average Sample Number for Sampling Inspection by Attributes in Acceptance Check

使用挑选型抽样方案进行验收时有两种方式:一是剔除检查中发现的不良品后接收所提交批的产品;另一是不但剔除已发现的不良品,而且要以良品补足后再接收该批产品.对于前者,接收一批产品所需的平均检验件数,已有结果;本文给出后者的平均检验件数的计算.

Two methods can be applied in sampling inspection with screening for acceptance:one is to accept the lot of products after picking out sub-quality products, another is to accept the lot of products after substituting acceptable prducts for sub-quality products.For the former,average sample number has been known.In this paper,calculation of average sample number for the latter is given.
