Validación de temparios del área de latonería de Mirasol S. A.

Abstract

In the service and manufacturing industry, several activities could be treated as projects, due to their uniqueness and temporality. In this sense, the brassware service is a clear example of this particularity, thus requiring tools that reduce uncertainty in terms of costs, time and quality. The tempario are important tools for mechanics and dealership services of dealers, allowing determining the cost and the time that will carry out the repair of the vehicle. The purpose of the validation of the tempario is to design a statistical model, which allows defining the preponderant variables to compare the observed times with the times established in the tempario and through a statistical analysis to evaluate if the tempario times are similar or not according to the times real work observed in the body shop. The validation process began with the development stage of the statistical model, where the population under study was identified, the necessary variables and the information was collected by applying a time study. In the second stage, the information obtained was tested and analyzed using the Chi-Square homogeneity hypothesis test. The result of the hypothesis test for the straightening temper concluded that the times obtained by time study are homogeneous with respect to the times established by the tempario. The result for the painting temperament concluded that there is no homogeneity with respect to the times obtained in the study of times.
