| 摘 要： | 研究了测量系统分析中对测量同一产品质量特性的两个测量系统能力的比较方法。基于广义推断法，提出了一种比较两个测量系统能力的方法。通过重复性与再现性（R&R）试验研究，利用广义推断法对两个测量系统能力的比较指数建立相应的广义置信区间，并进行计算机仿真。结果表明，基于广义置信区间的方法，可以有效地比较两个测量系统的能力。

| Abstract: | The method of comparing the capability of two measurement systems that measure the same quality characteristic in measurement system analysis is studied. Based on generalized inference, a method to compare two measurement systems capability is proposed. Through repeatability and reproducibility (R&R) studies, generalized confidence intervals for the comparison index of two measurement systems capability are built using generalized inference, and computer simulation is conducted. The results reveal that the proposed approach based on generalized confidence intervals can effectively compare capability of two measurement systems. |
