APPROACHES TO REPEATABILITY AND REPRODUCIBILITY ANALYSIS OF NON-REPLICABLE MEASUREMENT SYSTEMS

Measurement systems have to deal with processes in which, by the nature of the measured object or by the type of measurement itself, measurements are not repeatable in the sense that each sample unit can be measured only once. Such situations are usually referred as non-replicable measurement systems. The paper presents the approaches to GRR analysis in these cases. On the base of current development in this branch, the special attention is focused on the appropriate setup of GRR analysis and the choice which type of GRR design to use. The aim of the paper is to map out the current approaches to GRR analysis of non-replicable measurement systems with all the assumptions as for consistency, bias and temporal stability of objects. Subsequently, it is planned to verify these approaches in practice what is the opportunity to suggest the improving actions to obtain the results of high quality.
