Abstract
Intra-block remarshalling is the task of rearranging into some target bays those containers which are scattered around within the block, so that the containers can be loaded onto the ship efficiently. However, if we rearrange the containers without considering the container loading sequence, excessive rehandling work will be required at the time of loading because the containers to be fetched are often stacked under other containers. Therefore, the remarshalling should be done by moving the relevant containers in an appropriate order. This paper presents an efficient heuristic search technique for finding an appropriate container moving order during remarshalling to avoid rehandling at the time of loading. Simulation experiments have shown that the proposed method can generate rehandling-free solutions in real time.
