Managing container terminal operations in seaports is a cumbersome, complex and challenging problem. Given the importance of container traffic for international trade, it is surprising that this issue has been mostly tackled myopically. The problem involves a number of different criteria, such as faster discharge and loading of containers (vessel turnaround time), increased yard and equipment utilization, and faster container turnaround time. In this thesis, we begin with a literature review following the hierarchy of the decision-making process and then, we reveal the shortcomings of both the current practices in seaports and of the relevant academic efforts. Then, we present a novel hierarchical framework that captures systematically the complexity in the decision-making process recognizing its natural hierarchy (strategic, tactical and operational),the interdependencies among specific operations and the various forms of constraints including technological, spatial, temporal, monetary, and organizational as well as constraints imposed by the interests of various partners and customers of a port.
