This work was motivated by the need to contribute to the efficient distribution of products throughout the supply chain and to propose a management tool capable of reducing the high flow time of vehicles in the companies' distribution centers. Therefore, this article mainly proposes to create models that efficiently sequence the entry and exit of vehicles from the cross docking center, consolidating the main restrictions not considered together previously and minimizing the result of one of the main indicators in logistic organizations: o time of permanence of vehicles. In order to improve the computational efficiency of the proposed models, the study of variables and parameters involved in mixed integer linear programming is carried out, proposing options to reduce execution time. The models presented are based on allocation variables considering multiple dock constraints. The computational experimentation was performed using a set of 160 test-problems and the results showed that the difference between loading and unloading vehicles allocated on the day can better explain the variation in the results than the attributions of isolated variables.
