In addition, reinforcement learning can help integrate multiple transportation
                  modes simultaneously. For example, part of a shipment may be transported using slower
                  but environmentally friendly methods such as rail or inland waterways, while another
                  portion may be delivered through faster modes such as road transport or air freight.
                        Collaborative replenishment and transportation
                        Machine learning algorithms can be deployed within digital control tower systems
                  to monitor supply chain activities in real time. This enables companies to synchronize
                  replenishment cycles across multiple organizations and facilitate collaborative
                  transportation strategies.
                        Management of perishable inventory
                        Managing inventory for perishable goods is particularly complex because companies
                  must consider not only inventory levels but also the age distribution of products stored in
                  warehouses. Optimal inventory policies in such cases are often difficult to implement
                  using traditional analytical methods.
                        Reinforcement learning algorithms can develop effective heuristics through learning
                  processes, enabling firms to manage perishable inventory more efficiently.
                        Multi-channel supply chain management
                        When companies distribute products across multiple channels—such as physical
                  retail stores, e-commerce platforms, and international markets—reinforcement learning
                  algorithms can determine optimal inventory allocation strategies.
                        For example, AI systems can determine which products should be stored at local
                  warehouses to ensure rapid delivery, and which warehouses should fulfill specific
                  customer orders based on logistics efficiency and transportation costs.
                        3. Current situation of AI adoption in Vietnam's import–export logistics sector
                        3.1. Logistics in Vietnam’s international trade economy
                        Logistics plays a fundamental role in supporting import–export activities,
                  particularly for countries with high levels of trade openness such as Vietnam. According to
                  the Vietnam Logistics Report 2024, the country’s logistics market size is estimated at
                  approximately USD 65 billion, with an average annual growth rate of 14–16 percent [1].
                        The logistics sector contributes approximately 4–5 percent of Vietnam’s GDP and
                  provides employment for more than one million workers, making it one of the most
                  important service industries in the national economy.
                        Alongside the development of the logistics industry, Vietnam’s international trade
                  activities have expanded rapidly. In 2024, the country’s total import–export turnover
                  reached approximately USD 786 billion, and by 2025 this figure is projected to increase to
                  around USD 930 billion [2].
                        This remarkable expansion highlights the growing demand for modern logistics
                  services capable of supporting transportation, storage, and distribution activities within
                  global supply chains.
                        Vietnam’s export structure is currently dominated by manufactured industrial
                  products, which account for approximately 87–88 percent of total export value [1]. Major
                  export industries include electronics, machinery, textiles, and footwear. These sectors
                  rely heavily on efficient international logistics systems to transport raw materials and
                  distribute finished products across global markets.
                        As a result, the performance of the logistics sector has a direct impact on the
                  competitiveness of Vietnamese goods in international trade.
