This work aims at treating the Dynamic Vehicle Allocation Problem (DVAP) in the context of the Brazilian Freight Transportation system. The problem consists of allocating empty vehicles to different terminals so as to ...

The present study aims to address the problem of centralized supply of jobs. The motivation for the study is the practical situation observed in a large automobile industry located in the state of Minas Gerais. In more ...

We consider the capacitated lot sizing problem with multiple items, setup time and unrelated parallel machines, and apply Dantzig–Wolfe decomposition to a strong reformulation of the problem. Unlike in the traditional ...

The Vehicle Allocation Problem (VAP) consists in allocating a fleet of vehicles to attend the expected demand for road freight transportation between terminals along a finite multiperiod planning horizon. The objective is ...
