Resumen
ROMERO VEGA, Luis Esteban; VALDES LUNA, Luis Carlos; PASTOR DE MOYA, Jorge Guillermo y HERRERA ACOSTA, Roberto José. Statistical control for monitoring the process of cutting soap bars. Ing. Desarro. [online]. 2018, vol.36, n.2, pp.455-468. ISSN 0122-3461. https://doi.org/10.14482/inde.36.2.10514.
This study aims to apply the methodology of statistical process control charts in the monitoring of the net weight of soap bars of a production line, with the objective of evaluating the evolution of this variable as a characteristic of product quality; the results of traditional charts are compared to EWMA memory charts. In manufacturing processes where the misalignments are minimal, Shewhart charts may be less sensitive to these mismatches, which may take a long time to be detected. In this study are applied EWMA control charts that are more appropriate than traditional ones to detect small mismatches more quickly. Having the CEP charts for the monitoring and subsequent analysis of the process variables will enable timely detection of changes in product quality, evaluation of quality aspects of the manufacturing process and continuous improvement in the processes.
