Abstract
Focusing on the design of sub-assemble intelligent production line, an event-driven design method for production line was proposed. With the method, the manufacturing activity was defined as event, and then the relationships among events are analysed to define the input-output and execution behaviours digitally in each stage. Furthermore, the event-driven execution mechanism for multi-stage process was built to describe the production line in digital. The digital model of production line was conducted to explore the event behaviours, which will support the research about data-driven production line simulation in future work.

Summary
Shipbuilding is a discrete type manufacturing, so the subassemble manufacturing is not conducted in the form of flow production like auto-industry. With the development of intelligent manufacturing, the new technical change will come into shipbuilding, and intelligent production line become the important direction for shipbuilding transformation and upgrading. Sub-assembly is the typical structure in modern shipbuilding mode, which has the characteristics of large demands and variable types. The sub-assembly production contains many processes, including assemble, weld, repair, polish and back burning. The production mode of sub-assembly is the combination of manual operation and robot operation. Some shipyards have developed the production line for sub-assemble. Depending on the manufacturing technique of subassemble to improve the intelligent level, the production line of sub-assemble is designed. The digital model is established to support the data-driven simulation of production line
