Collaborative Optimization of Automatic Sorting System and Cross-Border Logistics The automatic sorting system does not operate independently, but deeply collaborates with the entire cross-border logistics chain. In the order link, the system seamlessly connects with WMS (Warehouse Management System) and ERP (Enterprise Resource Planning System), automatically synchronizes order data without manual entry; in the logistics link, after sorting, it automatically triggers the printing of logistics labels, and the label information matches the sorting destination in real time to ensure that the package is accurately sent to the corresponding logistics channel (such as DHL, FedEx, local post); in the tracking link, the sorting record generated by the system is synchronized to the logistics tracking platform, and overseas customers can check the package sorting status in real time. This collaborative optimization makes the connection of each link of "warehouse-transportation-delivery" in cross-border logistics smoother, and the overall logistics efficiency is increased by 30%-40%. For Alibaba International Station merchants, it can realize the visualization and controllability of the cross-border supply chain and improve operational efficiency.
