CSP-1-P方案的动态平均检出质量

THE DYNAMIC AVERAGE OUTGOING QUALITY ON CSP-1-P UNDER PROBABILITY SAMPLING

连续抽样方案(CSP)是Dodge于1943年提出的,适用于连续提交的在制品的检查。平均检出质量AOQ是CSP的基本指标,它表示长度为无穷的产品流经检查后其中所含不合格品数的长期期望比例,但实际生产中产品流的长度往往是有限的,因此AOQ并不能很好地反映方案的实际操作特性。 为弥补上述不足,人们提出了动态平均检出质量AOQ(t)的概念。

This paper deals with the single-level continuous sampling plan CSP-1-P in which probability sampling is used during sampling inspection.Theoretic formula and strict caloulating method are obtained by introducing transition probability flow graph,transition probability generating function and probability generating function.
