Abstract
Introduction. The labor performance in the activity of porcelain tile floor tile installation is key for an efficient planning of construction projects. However, even today, the planning of this performance is not carried out in a technical way and linearity is assumed in the results, without considering the variability of this performance as a function of external and internal factors of the workers. Objective. To propose a mathematical model to predict the labor performance in the installation of porcelain tile floors in the city of Cuenca, specifically in the Machángara parish. Methodology. A review of the literature related to the factors that influence the performance of workers in this activity was carried out. Based on this information, an observation sheet was designed that included 6 variables and 35 relevant indicators. A descriptive methodology of a correlational type with a quantitative approach was applied, collecting data from a sample of 5 buildings in the porcelain tile installation phase. Results. The results, analyzed statistically, revealed an efficiency of 98% of the proposed model in relation to the actual performance of the workers. In addition, it was evidenced that, in Machángara, the workers' performance is below the theoretical standard provided by the GAD of Cuenca. Conclusion. It is concluded that the mathematical models based on the factors studied are capable of accurately predicting the performance of the workers, which can improve the predictions and execution times of the site managers.
