Resumo

This work provides a theoretical study of the Green Vehicle Routing Problem (G-VRP), which is an NP-hard problem that generalizes the Vehicle Routing Problem (VRP) and integrates it with the green logistics. In the G-VRP, electric vehicles with limited autonomy can recharge at Alternative Fuel Stations (AFSs) to keep visiting customers. This problem was introduced by [3] and approached later by [4], and [5], all of which consider that consecutive AFSs visits are not allowed, i.e., a solution cannot have an edge between two AFSs. In this work, two G-VRP versions are investigated, (i) where consecutive AFSs visits are not allowed, and (ii) where consecutive AFSs visits are allowed, i.e., a solution may have an edge between two AFSs. This research proposes combinatorial properties and lower bounds which have the potential to strengthen the mathematical formulations for both G-VRP versions, thus improving exact solution methodologies.
