A container terminal is a location comprising of a seaside and container storage yard areas. In seaside areas, there are two tactical level planning decisions: i.e.: berth allocation and quay crane assignment problems. Meanwhile in container storage yard area, the planning of yard templates is concerned with the allocation of container storage space to each container vessel. These three tactical level decisions are interrelated and dependent on each other. This paper discusses the development of integrated planning of these three tactical level decisions at container terminals, namely berth allocation problem, specific quay crane assignment and multi-period container storage yard templates. The balance of shipping liners owners' requirement and port container terminal managers has been considered as the objective of this optimization model. This integrated tactical planning model is solved by using a functional integration framework with feedback loop structure. A numerical example is used as an illustration of the application of the integrated planning decision model in a container terminal that can result in a good solution.
