Due to the recent introduction of shipbuilding CIM in Japan, the process planning has been applied widely in shipyards. Hence, the accuracy of the process planning, which has been a basic problem until now, has became better, because the detail production information can be prepared in early stage using the product model of CIM. Furthermore, a compact hardware and software system have been popularized. However, the current system is probably limited to the rough schedule in all process, and the detail scheduling including the human allocation seems to depend yet on KKD (experience, feeling, confidence) of the managers at a working site. This paper has picked up the assembly process of hull construction as an example of the detail scheduling to establish an intelligent system for it, considering the movement of individual person as a human based system. The assembly process was assumed as a conveyer system with plural lines where a series of process-such as arrangement of steel materials, fitting, welding, and inspection-are carried out at constant tact time one by one by plural persons. The workers may move to another line when they have finished their own works at the stage. The analysis was made by a combination of simple linear equations, and a computer program was developed. The calculation result using a test data showed that the system was useful and effective.
