Abstract In this article, we propose a sampling plan called a multiple dependent state repetitive group sampling plan for variable inspection based on the process capability index Cpk. The proposed sampling plan is applicable for the inspection of normally distributed quality characteristics when both mean and variance are assumed to be unknown. This new plan under variable inspection will be very useful particularly in compliance testing. Tables are also constructed for the determination of optimal parameters for easy selection and implementation of the plan. The optimal parameters can be determined by using the approach of two points on the operating characteristic curve. Symmetric and asymmetric cases based on the fraction nonconforming by the lower and the upper specification limits are also considered. Advantages of the proposed plan are also discussed. It is also shown that the proposed plan outperforms other existing sampling plans under variable inspection.

基于过程能力指标的多重依赖状态重复组抽样方案的确定

摘要 在本文中,我们提出了一种基于过程能力指标Cpk 的变量检验抽样方案,称为多依赖状态重复组抽样方案。当均值和方差均未知时,建议的抽样计划适用于检验正态分布的质量特性。这种可变检查下的新计划将非常有用,特别是在合规性测试中。还构建了用于确定最佳参数的表格,以便于选择和实施计划。最佳参数可以通过使用运行特性曲线上的两点的方法来确定。还考虑了基于不符合规格上限和下限的分数的对称和非对称情况。还讨论了拟议计划的优点。还表明,在可变检查下,提议的计划优于其他现有的抽样计划。
