Abstract: In order to solve the problems of poor scheduling and inefficiency of transporters in block transportation at shipyard, this paper proposed a framework of multiple transporters for block transportation scheduling systems with a digital twin-based (DT) five-dimensional model. The proposed framework can be used to identify low-efficiency of multidisciplinary, multi-physics, multiscale, and dynamic changes over time at shipyards to optimise the efficiency of multiple transporter scheduling and block transportation. DT provides the fidelity required to realistically predict transporter scheduling schemes with rescheduling actions under various interference conditions. The high-fidelity model is investigated using three levels of geometry, dynamics and data. An optimal simulation model experiment with multiple transporters is adopted to improve transportation efficiency. The results show that the proposed DT framework and high-fidelity model are effective, and both the utilisation of transporters and the transportation efficiency of blocks are improved.
