Abstract: To realize the whole life cycle management of goods distribution and the service optimization of distribution process,the digital twin technology was introduced into the distribution management,and the distribution management system based on digital twin concept was proposed.The application requirements of this system were analyzed firstly,and the system architecture and functional structure were established.Moreover,a construction method of the digital twin models for the distribution process was proposed.Under the guidance of this method,the basic digital twin of distribution process,the digital twin model of packing planning and the digital twin model of distribution process optimization were constructed.The packing scheme and interactive adjustment method oriented to digital twin model were also established,a dynamic visual interactive packing layout method based on digital twin was formed.The function of the digital twin distribution management system was demonstrated by a distribution example.It was proved that the distribution management system based on digital twin was effective and feasible,which could improve the packing effect and optimize the distribution process reasonably.
