田口提出了一种可变质量评价方法，称为“田口质量损失”来代替不合格品比例等属性质量评价。Arizono等人从保证田口质量损失的角度出发，提出了基于操作特性的单一验收抽样方案。本抽样方案的设计是为了保证每个批次在允许的质量损失限额和不允许的质量损失限额的规定接受概率的约束。但是，在基于运行特性的验收抽样计划中，没有规定不合格批次的纠正措施。另一方面，带筛选的抽样检验计划被称为带不合格品纠正措施的抽样方案。其次是带筛选的属性抽样检验方案，以保证不合格品在发货批次中所占比例的期望值。但是，有筛选的可变抽样检验方案尚未规定。然后，为了保证以田口损失为指标的最大期望盈余损失的上限，本文提出了一种带有筛选程序的变量抽样方案。
Taguchi has proposed a variable-quality evaluation called “Taguchi’s quality loss” instead of the attribute quality evaluation such as the proportion of nonconforming items. Arizono et al. have proposed a single acceptance sampling plan based on operating characteristics from the viewpoint of assuring Taguchi’s quality loss. This sampling plan is designed to guarantee the constraints of the prescribed acceptance probabilities for respective lots with the allowable quality loss limit and the unallowable quality loss limit. However, in the acceptance sampling plan based on operating characteristics, the corrective action for rejected lot is not prescribed. On the other hand, the sampling inspection plan with screening is well known as the sampling scheme with the corrective action for rejected lots. Then, there is the attribute sampling inspection scheme with screening in order to guarantee the expectation of the proportion of nonconforming items in the shipping lot. However, the variable sampling inspection scheme with screening has not yet been prescribed. Then, in this article, we propose a variable sampling scheme with screening procedure for the purpose of assuring the upper limit of the maximum expected surplus loss indexed by Taguchi’s loss.
