Spatial Scheduling for Assembly Blocks in Shipbuilding Based on Rules

Block assembly consumes the majority of processing time and resources in shipbuilding, improper stacking may produce extra operation, so the block spatial scheduling has been widely studied as the key to improve shipbuilding efficiency. In order to minimize the extra operation, the paper design a dynamic scheduling method through the formulation of rules. Extensive numerical experiments based on realistic date of a shipyard shows that the proposed method can solve real-case problems efficiently. The results demonstrate that the method can reduce more than 20% of extra operation.
