Abstract
Multi-variety, small-batch or personalized customer demand increases the frequency affected on the transportation process of Port Hinterland Logistics System (PHLS). To keep the PHLS in the optimal state, the whole system should adjust the configuration structure, operational planning and control mechanisms to adapt to the dynamics. The core challenge of the PHLS at this stage is how to identify dynamics accurately and real-timely, and control the operation of the PHLS to keep its state in an optimal state. the Digital Twin-based control framework (DTCF) and Twin-Optimal synchronization mechanism (TWSM) are proposed in this study to deal with the impact of dynamics in PHLS. Digital twin is referred to achieve the mapping of physical resources and virtual resources, and to verify the feasibility of the transportation plan developed by the control center through repeated iterations of virtual resources during the planning stage. In the process of transportation, the TWSM can be used by decision layer to response the impact of dynamics on fleet structure, load control or path planning of PHLS. At last, a case study is used to validate the effectiveness of TWSM.
