摘要：In modern production processes, a large amount of testing and measurement is performed to support decision making and to ensure quality. In order to achieve this, the measurement data needs to be reliable, and the capability of measurement systems needs to be verified. Gauge reliability and reproducibility (GRR) is used for quantifying and analysing the variation in results caused by the measurement system. The purpose of this study is to introduce a simple method to assess GRR performance when there are two parallel measurement systems. The study shows that with certain assumptions, the Pearson correlation between measurement results of two measurement systems can be expressed using the GRR indices of these systems. This implies that the GRR performance of these measurement systems could be analysed based on this correlation. In certain situations this could save significant time compared to regularly performed GRR studies.
