Abstract: La experiencia adquirida como inspector de calidad (producto en proceso y terminado) en el área de Control de Calidad de la empresa Leche Gloria S.A, ha incidido directamente en el desarrollo del presente informe de investigación titulado “Aplicación de un control estadístico para la mejora del proceso de envasado de leche UHT bolsa”. Se realizó un análisis general sobre el problema del sobrellenado de envases, utilizando el diagrama de Ishikawa y posterior a ello se usó el diagrama de Pareto para delimitar aún más la posible causa del problema, en donde se encontró que la principal causa del sobrellenado era la deficiente exactitud de la máquina Thimonnier M4200 AS (líneas 1 y 2, lados A, B). Entre las herramientas de calidad utilizadas, se encuentran el diagrama de causa efecto o Ishikawa, diagrama de Pareto, gráficos o cartas de control (X-R), diagrama de dispersión e histogramas. En cuanto al control estadístico de procesos, primero, se verificó la normalidad del proceso antes y después del cambio de cánula mediante un diagrama de dispersión (método Anderson-Darling), posteriormente se utilizaron los gráficos de control (X-R), con los cuales se determinó que la naturaleza de la causa generadora del problema era de tipo especial, y por último, mediante el cálculo de los índices de capacidad y centrado se llegó a la conclusión que el proceso de envasado de leche entera UHT mejoró al pasar de una clase 4 a la 1 para índices de capacidad de corto plazo, y al pasar de una clase 4 a la 2 en índices de capacidad de largo plazo. Además, se mejoró el centrado del proceso (k) al pasar de un valor de 26.82% a 7.26%.
ABSTRACT The experience acquired as a quality inspector (product in process and finished product) in the area of Quality Control of the company Leche Gloria S.A, has had a direct impact on the development of this research report entitled "Application of a statistical control for the improvement of the packaging process of UHT milk bag”. A general analysis was carried out on the problem of overfilling of containers, using the Ishikawa diagram, then the Pareto diagram was used to further narrow down the possible cause of the problem, where it was concluded that the main cause of overfilling was the poor dosage and accuracy of the Thimonnier M4200 AS machine (line 1, side B). Among the quality tools used, are the cause-effect or Ishikawa diagram, Pareto diagram, graphs or control charts (X-R), dispersion diagram and histograms. Regarding the statistical control of processes, first, the normality of the process was verified before and after the change of cannula by means of a dispersion diagram (Anderson-Darling method), subsequently, were used control charts (X-R), with which it was determined that the nature of the cause that generated the problem was of a special type, and finally, by calculating the capacity and centering indices, it was concluded that the UHT whole milk packaging process improved when passing from a class 4 to 1 in short-term capacity indices, and when passing from a class 4 to 2 in long-term capacity indices. In addition, the centering of the process (k) was improved by going from a value of 26.82% to 7.26%.
