In this thesis, we present a mixed integer linear programming model for the operational level cargo allocation and vessel scheduling problem, where flow-dependent port-stay lengths, transit times and transshipment schedule synchronizations are considered. The proposed model aims to assign shipments to routes to minimize total tardiness, and construct vessel partial schedules for establishing coordination with port authorities to meet the berthing time windows. In addition to mathematical model, novel valid inequalities are proposed, and a benders decomposition algorithm is implemented. Algorithm performances are tested on real-life problem instances. The results show that benders decomposition with valid inequalities yields the best performance on the test instances. The thesis is further extended with the consideration of instant terminal port performances, and an integrated solution framework is proposed for this dynamic problem. The thesis study aims to contribute to both the practitioners and to the state-of-the-art literature.
