The use of the Krippendorff’s Coefficient in determining intra-rater reliability in human visual quality control of furniture manufacturing processes. The article presents the results of research on the effectiveness of human visual quality control of furniture manufacturing processes. The aim of this experiment was to check the inter-rater reliability of three elements: the judge, the instruction of which the quality of individual objects made of laminated MDF was determined and the quality assessment by a human. The Krippendorff’s Coefficient was used as a measure of visual control effectiveness. The results of the experiment showed that the use of human visual quality control of furniture manufacturing processes can be a good solution. T...
