【 摘 要 】

This article summarizes the main results of the statistical control carried out to the production of poles for aerial networks in the Unidad Empresarial de Base Planta de Impregnación located in the Agroforestry Enterprise Macurije, in the province of Pinar del Río. In carrying out the investigation, the problem identified by customers related to the low quality of the final product of the impregnation process of poles for aerial networks was taken into account. Consequently, the objective of this article is to identify the causes of the quality defects of the utility poles in the impregnation process at the UEB Planta de Impregnación. For the statistical control of quality defects, control graphics were used for attributes, specifically the graphics for the number of defects per unit and Poisson capacity analysis using Minitab 17.0 software, as well as the Current Reality Tree for the identification of root causes. Based on the diagnosis made, poles were identified that do not comply with the quality indicators established in the labor standards; in addition to a failure to meet the demand for these products, causing customer dissatisfaction. At the same time, the root cause of the defects was identified as deficiencies in the production process.
