Sažetak
The transport of empty containers represents a serious problem in the fast growing sphere of maritime container transport. The most widespread type of container transport organization in maritime transport is the hub and spoke mode, which enables the transport of a great number of containers via large vessels between hub ports, from where feeder ship transport to smaller ports that thus gravitate to the central hub ports. The article containes a detailed analysis of the nothern Adriatic ports and the feeder connection with the hub ports of the Mediterranean. A two-level VRPPD (Vehicle Routing Problem with Pickup and Delivery) problem is modelled on a graph, where the transport of full containers is privileged over the transport of empty containers. This enables the simulation of the feeder system in the nothern Adriatic, meaning that it shows the ship s operator the movement programme with minimal transport costs for the superfluous empty containers in the complex of the regular transports of full containers in the feeder system.
