A Mathematical Model and An Industrial Application for Green Vehicle Routing Problem with the Heterogeneous Fleet and Capacity Constraints

Today, environmental factors and sustainability concepts are taken into account along with operational criteria in Vehicle Routing Problems (VRP). The VRP that addresses environmental factors is called Green VRP (GVRP). One of the most critical factors causing global warming is carbon emissions. In GVRP, carbon emissions should be taken into account with operational costs. This study proposes a mathematical model for Green Capacity VRP (GCVRP). It is aimed to solve GCVRP by considering vehicles with different characteristics. The proposed model has been applied to determine the routes of personnel service vehicles in a furniture company. The obtained results show that the proposed mathematical model can give successful results for GCVRPs.
