Confidence Intervals in a Gauge R&R Study with Fixed Operators

Abstract

AbstractThe objective of this paper is to develop a method for constructing confidence intervals in a two-factor gauge repeatability and reproducibility (R&R) study with fixed operators. A previously proposed method is compared with a generalized confidence interval method using computer simulation. Simulation results suggest that, although the two methods are comparable in most cases, there are situations where the generalized confidence interval is a better choice.KeywordsAnalysis of VarianceGauge StudiesMeasurement Systems Capability AnalysisVariance Components Additional informationNotes on contributorsLorraine DanielsLorraine Daniels is a Doctoral Student in Industrial Engineering.
