Repetitive Testing Strategies When the Testing Process Is Imperfect
研究测试不完美时，重复测试被拒品或合格品哪种策略更好，并分析测试精度、容量、来料质量与出厂要求的关系，帮助工程师优化测试流程。
This paper considers the problem of test design and implementation when testing is imperfect. Items that are classified as conforming may be nonconforming, resulting in a poor outgoing quality level. Items that are classified as nonconforming may be conforming, resulting in excessive scrapping of conforming items. The failed items are commonly retested to reduce the scrapping problem. Alternatively, the accepted items may be retested to improve outgoing quality. In this paper, we examine the question of whether it is better to repetitively test rejected items, or to repetitively test accepted items. We also examine the relationship between the two testing policies, testing equipment accuracy and capacity, incoming quality, and outgoing quality requirements.
