The structure of the paper is as follows. The next section presents an up-to-date literature review of
shipper and shipper-carrier models. The third section defines the general maritime freight transportation
network structures. The fourth section proposes modeling approaches for the shipper problem, carrier
problem and shipper-carrier problem, and makes solution algorithm recommendations. The next section
presents a numerical example, demonstrating the applicability of the model. The last section summarizes
and concludes the paper.
