Block assembly in shipbuilding is mainly concerned with cutting and welding operations to construct a block. A block is composed of several steel plates and sections with various sizes and shapes. Process planning for block assembly is to generate cutting and bending operation plans, assembly processes and sequences, and welding operation plans to construct a block. This paper deals with the development of an automatic process planning system for block assembly in shipbuilding. Part assembly graph that is a semantic network type of representation scheme for block structure is proposed and used to represent block information. The approaches adopted are case-based reasoning for block assembly process planning and rule-based reasoning for process planning of cutting and welding operations. The prototype system has been implemented and verified using real blocks in the block assembly shop.
