Abstract

In a large mining site, the equipments are operational in a vast geographic region, and some of these equipments have locomotion restrictions, such as shovels, tractors, and drills. Due to these limitations, these types of equipment need to be supplied at their places of operation using fuel trucks with supply infrastructure, called fuel convoys. In this study, we addressed the routing problem of these fuel convoys seeking to minimize the longest route. To solve the problem, we propose a mixed-integer linear programming formulation. We have validated this formulation using data from the Carajás Complex, Vale S.A, in Pará-PA. The results showed that the formulation is able to find good solutions to the problem and can be used to support decision-making.
