MORFIN-MAGANA, Rodrigo et al. Measurement system analysis by attributes in quality inspection for blackberries. Ing. invest. y tecnol. [online]. 2023, vol.24, n.3.  Epub Nov 17, 2023. ISSN 2594-0732.  https://doi.org/10.22201/fi.25940732e.2023.24.3.018.

This paper describes an experimental process to evaluate the efficiency of the attributes measurement systems used for blackberry quality in packing companies is described. A characteristic of this type of measurement system is its qualitative nature and the subjective assessment that quality inspectors use to assess the fruits. In this work, the analysis results of the attributes measurements systems used in two different packing companies are presented, which obtained contrasting results in the concordance analysis, that are compared through the value of the Fleiss’ Kappa statistical coefficient. The differences obtained in the two case studies are analyzed using additional data describing the characteristics of each measurement system used, which suggests a relevant factor for the results obtained in each company. Finally, the work presents a discussion of the possible improvement actions for designing and implementing an attributes measurement system for blackberry packing companies.

Keywords : Quality assessment; attribute measurement system; visual assessment; Fleiss’ Kappa.
