Abstract
Nowadays, there exists a large competition between maritime ports, so that the improvement of customer service became a serious important problem within port container terminals which led to several sub-problems (Vis and Koster 2003). One of these sub-problems is the Container Stacking Problem. A container stack is a type of temporary store where containers await further transport by truck, train or vessel. The main efficiency problem for an individual stack is to ensure easy access to containers at the expected time of transfer. Since stacks are 'last-in, first-out', and the cranes used to relocate containers within the stack are heavily used, the stacks must be maintained in a state that minimizes on- demand relocations. In this paper, we study and compare the configuration of yard-bays with 4 tiers and yard-bays with 5 tiers.
