Abstract

Under the uncertain conditions and time-varying operating environment, dynamic planning and scheduling have become the key problem, which must be solved to improve the program feasibility, production efficiency, and reducing construction costs during the ship intelligent manufacturing process. A scheduling optimization method based on digital twin is proposed. Firstly, the real-time and dynamic requirements of segment construction scheduling are analyzed, and the technical framework of subsection construction scheduling based on digital twin is established; Secondly, a digital twin model for subsection construction of ships is constructed, and the twin data-driven scheduling method which is based on the IOT system and rescheduling method is established for subsection construction. Finally, through the scheduling process optimizing in the shipyard subsection construction, the effectiveness of the proposed method is proved.
