In order to achieve product plan for the composite digital production line and make it more operational, Based on the difference of material used to main process of production line, the composite production plan is departed in two stages: Partition plan and Machine plan. By analyzing project of aircraft composites workshop production plan, the methods are given to make partition plan and machine plan for composite components, and this system is taken into practices for composite workshop in digital production line. Practice shows that this type of approach can be effective during making practical production planning, and improve the ystem’s development, maintenance, and good scalability.
