ALVIS GORDO, JOSÉ FRANCO  e  SOTELO MUNOZ, MANUEL ALBERTO. IDENTIFICATION OF THE CAUSES THAT ALTER THE PERFORMANCE OF TEAMS LOGGING: STUDY TIME AND MOVEMENT. Rev.Bio.Agro [online]. 2009, vol.7, n.2, pp.15-23. ISSN 1692-3561.

The time and motion studies to identify the causes that decrease the performance of logging equipment during the harvest, diagrams routine movements to determine the cycles (production unit) to get the optimum performance each group studied. Statistical analysis was performed using a multiple linear regression can predict the behavior of variables and formulate a mathematical model that predicts the performance of each team, depending on different variables such as slope, distance Woodlot and cargo carried. We designed a mathematical model that predicts yields Woodlot operations to an average distance of 250 meters, slopes between 30 and 45% in plantations of Pinus tecunumanii, oocarpa Pinus, Pinus patula and Eucalyptus grandis.
