Abstract
El presente trabajo de investigación tuvo como objetivo determinar si las variables de calidad de exportación de la palta Hass en la empresa Pedregal S.A. periodo abril-mayo 2022 está bajo control estadístico multivariante de calidad. La población estuvo constituida por la producción total diaria de palta Hass durante el periodo de producción del año 2022 y para determinar la muestra se utilizó la estrategia de la norma técnica ISO 2859-2013 en el cual se consideró el muestreo simple y el nivel de inspección normal (nivel de inspección II), identificándose la letra G, en la tabla 2 de la norma, por lo que se concluyó que la muestra fue de tamaño n=32 días de producción, obteniéndose una de 10 unidades de palta Hass para su evaluación,
considerando un total de n=320 paltas Hass a evaluar. Las conclusiones obtenidas es que las variables de calidad de exportación de la palta Hass en el proceso de producción de la empresa “Pedregal S.A.” si están bajo control estadístico multivariante; considerando los límites de especificación para la materia seca entre 21.5% y 27.5% y para el aceite entre 8.1% y 11.3, el valor que se obtuvo del Índice de capacidad multivariante (MCpk) cuyo valor es de 0.69 lo que indica que el proceso no está centrado, generando 18705 paltas defectuosos por un millón de ellas y como conclusión final la empresa “El Pedregal S.A.” debe implementar planes de mejora para corregir y ajustar su proceso productivo acorde a los límites de especificación para exportar la palta Hass
ABSTRACT The objective of this research work was to determine whether the export quality variables of the Hass avocado in the company Pedregal S.A. April-May 2022 period is under multivariate statistical quality control. The population was made up of the total daily production of Hass avocado during the production period of 2022 and to determine the sample the strategy of the technical standard ISO 2859-2013 was used in which simple sampling and the inspection level were considered. normal (inspection level II), identifying the letter G, in table 2 of the standard, so it was concluded that the sample was of size n=32 days of production, obtaining one of 10 units of Hass avocado for evaluation, considering a total of n=320 Hass avocados to be evaluated. The conclusions obtained are that the export quality variables of the Hass avocado in the production process of the company “Pedregal S.A.” whether they are under multivariate statistical control; Considering the specification limits for dry matter between 21.5% and 27.5% and for oil between 8.1% and 11.3, the value obtained from the Multivariate Capacity Index (MCpk) whose value is 0.69, which indicates that the process does not is focused, generating 18,705 defective avocados for a million of them and as a final conclusion the company “El Pedregal S.A.” You must implement improvement plans to correct and adjust your production process according to the specification limits for exporting the Hass avocado
