The mixed fleet vehicle routing problem with partial recharging by multiple chargers: Mathematical model and adaptive large neighborhood search

•Mixed Fleet Vehicle Routing Problem with Multiple Chargers (MF-VRP-MC) is addressed.•The MF-VRP-MC includes electric and internal combustion vehicles.•A mixed integer mathematical programming formulation for the MF-VRP-MC is developed.•An ALNS algorithm with new initialization and neighborhood mechanisms is proposed.•Computational results reveal that ALNS performs quite well on test instances.
