Taguchi（1985，1986）在研究中提出的质量损失被认为是一种新的质量评价方法，它取代了传统的质量评价方法--重复项目的比例。近年来，在质量损失的概念下，各种保证批量质量的验收抽样检验方案得到了发展。本文从实用性的角度出发，提出了一种基于质量损失的可变两阶段抽样检验方案，作为一种以有限次抽样检验为终点的新型二次抽样检验方案。同时，在新制定的变量两阶段抽样检验方案中，考虑减少抽样检验所需的平均样本数。建立了抽样检验方案的设计过程，并通过数值比较说明了抽样检验方案的有效性。
The quality loss proposed in studies by Taguchi (1985, 1986) has been recognized as a new evaluation measure of quality instead of using the proportion of nonconforming items known as the traditional evaluation measure of quality. In recent years, various kinds of acceptance sampling inspection plans for assuring lot quality under the concept of the quality loss have been developed. In this paper, we propose a variable two-stage sampling inspection plan based on the quality loss as a new type of double sampling inspection plan that is terminated at finite sampling inspection from the viewpoint of practical usefulness. At the same time, reducing the average sample number required for sampling inspection is considered in the newly developed variable two-stage sampling inspection plan. The design procedure for the developed sampling inspection plan is established, and then usefulness of the sampling inspection plan is shown through numerical comparison.
