Are there any benchmark instances for VRP with charging stations? I also have various delivery points with charging stations in the city(Multiple Vehicles). How can I compare my formulation?
E-VRP-NL has been used in The electric vehicle routing problem with capacitated charging stations. Also authors in the paper mentioned by A.Omidi design two new sets of benchmark instances for the E-VRPTW problem. A set of 56 large instances, each with 100 customers and 21 recharging stations, and a set of 36 small instances with 5, 10, and 15 customers per instance. All instances are created based on the benchmark instances for the VRPTW proposed by Solomon (1987).
