“…The development of VRP research includes problems with heterogeneous fleets, time windows, split delivery, and pick-up and delivery problems. Some of the best known VRP developments are the Vehicle Routing Problem with pick-ups and delivery (VRPPD) [5], [6], [7]; Vehicle Routing Problem with split delivery (SDVRP) [8], [9]; Vehicle Routing Problem with time window (VRPTW) [10], [11], [12], [13], [14]. Besides the VRP types above, there are several other types of VRP developments such as the Periodic Vehicle Routing Problem (PVRP), Multi Depot Vehicle Routing Problem (MDVRP), Capacitated Vehicle Routing Problem (CVRP), Green Vehicle Routing Problem (G-VRP).…”
