A lot of fieldworks have been done to collect the runtime data of the workshop in several famous shipyards. A survey is carried out among the workers and engineers to get the important information during practical production, such as production process, resource distribution, facility layout, etc. A simulate software named SSHM (Simulation for Ship Hull Manufacturing) is developed for the design of the automated ship hull manufacturing workshop by using object-oriented methodology. Analysis and Evaluation of productivity for the design project is also carried out.
