摘要
在生产过程中 ,测量系统的好坏是成功实施质量改进或应用统计过程控制的先决条件。测量系统的性能评价称之为量具的重复性和再现性 (R& R)研究。本文首先根据二因素随机效应模型 ,给出了估计 R& R的一种方法 ,它克服了方差分析方法的某些不足 ;其次 ,当测量系统满足能力要求时 ,提出了监控测量过程的方法 ;最后 。
In production process, good measurement systems are important for successful quality improvement or statistical process control. The assessment of a measurement system is known as a gauge repeatability and reproducibility (R&R) study. We first provide a simple method for estimating R&R based on two way random effects model, which overcomes the drawbacks of analysis of variance (ANOVA) method. Then we propose a method to control such a measurement process. Finally, we briefly introduce software design for the analysis and control of a measurement process.
