Abstract
The outbound operation of steel plate yard is a time-consuming job in shipbuilding. Crane should retrieve outbound plates from different stacks. If the outbound plates are blocked by other plates, relocation is required in advance to replace blocking plates to other stacks. To reduce the unproductive relocation, the retrieval and relocation operation should be well-planned. In this paper, we proposed a stack-based outbound operation method. Outbound plates are retrieved based on a specific stack sequence and blocking plates are relocated as much as possible to stacks without outbound plates. We proposed the mathematical model of this method, and a heuristic algorithm is introduced. The computational experiment shows that our method can get good results in a short time.
