Abstract

In this paper, an attri-vari inspection policy for the resubmitted lots based on the process capability index C_pk is proposed. The proposed sampling plan comprises of both attribute and variables inspections for the resubmitted lots using single sampling plan. In the case of variables inspection, both symmetric and asymmetric fraction non conforming cases have been considered. Tables are developed and constructed for determining the optimal parameters of the proposed mixed plan based on two points on the operating characteristic curve approach by formulating the problem as a non linear programming. The industrial application of the proposed mixed sampling plan is explained with an illustrative real time example. Advantages of the proposed sampling plan are also discussed in terms of comparison with other existing sampling plans.

摘要

本文提出了一种基于工艺能力指数C _{pk的重提交批次的attri-vari检验策略}被提议。提议的抽样计划包括使用单一抽样计划对重新提交的批次进行属性和变量检查。在变量检查的情况下，对称和非对称分数不合格情况都已考虑。通过将问题表述为非线性规划，基于运行特性曲线方法上的两个点，开发和构建表格用于确定提议的混合计划的最佳参数。所提议的混合抽样计划的工业应用通过一个说明性的实时示例进行说明。在与其他现有抽样计划的比较方面，还讨论了提议的抽样计划的优点。
