proposta de roteirização aplicada ao transporte de argamassas industrializadas - estudo de caso

Abstract

In Brazil, the road transport modal is the most used for the delivery of goods where the main objective is the delivery at the customer's address, wherever it may be. Allied to this, the logistics and the study of strategies must be well aligned for there to be a satisfactory revenue gain and not cause damage to companies with logistics costs, since labor, cost of inputs, products, taxes, among others, consume more than 88% of the value of the product of a single delivery. Planning, goods delivery, and invoicing are important items for those who constantly work with perishable goods deliveries, in several stops, and with a great market competitiveness, since the best service will always be chosen by the customers. Deliveries on time, even more related to stabilized mortar for masonry laying that has a validity period counted in hours, that is, 72 hours for its expiration, every lost time is important. For this, along with the free software QGis, and plugins installed on it, it was proposed the vehicle routing where it solves the Traveling Salesman Problem, guaranteeing the shortest route in the least time, visiting delivery points only once, optimizing this route in the best way possible and analyzing a profit of approximately R$470.000,00 in one year in the Stabilized Mortar dosing centers for masonry laying.
