Description

Technical Field

[0001] This invention relates to the fields of artificial intelligence and unmanned system scheduling and control, and in particular to a collaborative method for unmanned personnel flow based on multi-agent continuous learning. Background Technology

[0002] With the advancement of smart ports, smart customs, and intelligent logistics infrastructure, customs clearance operations are facing increasingly stringent requirements for transportation timeliness, operational safety, process traceability, and regulatory compliance. Within the port area, the process of goods unloading, temporary storage, inspection, transfer, and release often involves the parallel operation and coordinated cooperation of multiple types of equipment, such as unmanned vehicles, drones, transfer cabinets, gates, or checkpoints. Compared to common park delivery or warehouse handling, customs clearance scenarios without human or goods flow are characterized by long operational chains, dense parallel operation of multiple vehicles, frequent cross-regional relays, strong constraints on passage permissions and time windows, rapid iteration of regulatory rules, and numerous unforeseen events. Insufficient scheduling and coordination capabilities can easily lead to channel congestion, failed handovers, resource competition, delays, and even the risk of failing to meet regulatory constraints, thereby affecting overall customs clearance efficiency and regulatory safety.

[0003] Existing unmanned logistics systems primarily employ three methods in customs clearance scenarios. The first method involves manually pre-setting rules and static scheduling, such as fixed priorities, fixed routes or areas, fixed handover nodes, and threshold-triggered replanning, combined with heuristic or offline path planning and resource allocation algorithms. This method is simple to implement and highly controllable, but it heavily relies on human experience and scenario assumptions, resulting in high rule maintenance costs. When regulatory rules are adjusted, checkpoint strategies change, site layouts are modified, or business volume fluctuates, existing rules often become ineffective, requiring frequent manual intervention or reconfiguration. This makes it difficult to guarantee overall optimization and real-time performance under complex conditions, and it also lacks sufficient coverage for long-tail anomalies.

[0004] The second type of method involves multi-agent strategies trained offline in a single instance. These strategies utilize historical data or simulation environments to train multi-agent learning policies for tasks such as device allocation, path selection, or local collision avoidance. While these methods may perform well in fixed environments, the scenarios presented are subject to constantly changing rules and disturbances. Training often relies on relatively stable reward designs and environmental distribution assumptions. When new regulatory rules are introduced, inspection strategies are adjusted, temporary lockdowns occur, equipment malfunctions occur, or new risk events emerge, the strategy's generalization ability is insufficient, leading to a sharp performance drop. Furthermore, adapting to these changes typically requires re-collecting data and retraining the entire system, which is time-consuming, costly, and difficult to implement quickly in real-world operations.

[0005] The third category of methods involves online adaptive or local replanning approaches, which address disturbances through rolling optimization, local search, or online fine-tuning of the strategy. While these methods can improve response speed to some extent, they are prone to getting trapped in "local optima," leading to global coordination imbalances. For example, congestion might shift from one region to another, or queuing at handover nodes might worsen. Furthermore, without effective stabilization mechanisms, online updates can lead to policy drift, causing the forgetting of existing effective coordination strategies and resulting in performance fluctuations and uncontrollable risks. In customs clearance scenarios that emphasize compliance and auditability, such instability significantly reduces system reliability.

[0006] Therefore, existing technologies generally suffer from the following shortcomings: difficulty in continuously evolving with changes in regulatory rules and the environment; insufficient systemic coordination capabilities for multi-vehicle parallel and cross-regional relay operations; weak response to long-tail risk events; and susceptibility to forgetting or requiring costly retraining during strategy updates, making it difficult to balance long-term stable operation and rapid adaptation. Therefore, there is an urgent need to provide a human-machine interface-based collaborative method based on continuous learning of multiple agents to address these issues. Summary of the Invention

[0009] S2, Multi-agent collaborative decision-making mechanism: Under a unified constraint framework, each agent acts jointly based on local observations and shared customs status information. When disturbances occur, online replanning is triggered to generate alternative paths, alternative handover points, and alternative resource allocation schemes for execution, ensuring that the customs clearance link remains unbroken and meets compliance constraints.

[0010] S3, Self-Game Scenario Generation and Strategy Learning: Construct a collaborative-adversarial hybrid training mechanism to automatically generate multiple types of customs clearance adversarial scenarios through self-games, so as to learn collaborative strategies under different loads and rule combinations. At the same time, introduce multi-objective learning criteria consistent with customs objectives to achieve a balance between customs clearance timeliness, resource utilization, risk control and compliance.

[0070] Figure 1 The flowchart is for a specific implementation method. Detailed Implementation

[0071] To explain in detail the technical content, structural features, objectives, and effects of the technical solution, the following description is provided in conjunction with specific embodiments and accompanying drawings.

[0072] The motivation behind this invention is to construct a decision-making system capable of maintaining collaborative efficiency and compliance under the dynamic and highly constrained environment of unmanned logistics in customs clearance, amidst rule updates, layout changes, and disturbance events. To this end, this invention proposes to uniformly model unmanned vehicles, drones, transfer lockers, and checkpoints as a multi-agent decision-making system. It generates diverse collaborative and adversarial scenarios through self-games and other methods to learn key decision-making strategies, and introduces a continuous learning mechanism to ensure the system can continuously update itself when new rules or events occur, minimizing forgetting. Simultaneously, it leverages cross-agent knowledge sharing to enhance group collaboration capabilities, thereby improving the scalability, portability, and operational stability of unmanned delivery within customs areas under complex and changing conditions.

[0073] like Figure 1 As shown, this embodiment provides a human-free flow-based collaborative method based on multi-agent continuous learning, including the following steps:

[0074] S1, Scenario Modeling and Constraint Representation: The infrastructure such as the customs area road network, operation zones, handover nodes, checkpoints or gates, inspection positions, and transfer cabinets, as well as execution vehicles such as unmanned vehicles and drones, are abstracted into a multi-agent system; customs supervision rules, such as: passage permissions, time windows, inspection priorities, sealing status, checkpoint release strategies, prohibited or restricted areas, are formalized into computable constraints and compliance judgment conditions, and a task state machine consistent with the customs clearance business process is established to describe the state transitions of key links such as arrival, handover, queuing, inspection, and release;

[0075] S2, Multi-Agent Collaborative Decision-Making Mechanism: Under a unified constraint framework, each agent takes joint actions based on local observations and shared customs status information, such as making decisions on equipment or capacity allocation, task assignment, route selection, handover node selection, and arrival timing; when disturbances such as checkpoint congestion, queue jumping, channel closure, or equipment failure occur, online replanning is triggered to generate executable alternative routes, alternative handover points, and alternative resource allocation schemes to ensure that the customs clearance link remains unbroken and meets compliance constraints;

[0076] S3, Self-Game Scenario Generation and Strategy Learning: Constructing a collaborative-adversarial hybrid training mechanism, which automatically generates multiple types of customs clearance adversarial scenarios through self-games, such as peak congestion, increased proportion of temporary inspections, checkpoint flow control, severe weather restricting drones, and risk warnings triggering secondary inspections, to learn collaborative strategies under different loads and rule combinations; at the same time, introducing multi-objective learning criteria consistent with customs objectives, so that the strategy achieves a balance between customs clearance timeliness, resource utilization, risk control and compliance;

[0077] S4, Continuous Learning and Incremental Rule Adaptation: When new regulatory rules, site layout modifications, checkpoint strategy updates, or new long-tail risk events occur, the system adopts a continuous learning approach for incremental updates. Through mechanisms such as constraint replay, parameter regularization, and sample reweighting, catastrophic forgetting is suppressed, enabling the strategy to adapt to new rules while maintaining stable performance on existing clearance modes. It also supports the rapid injection of new knowledge in the form of "rule change packages, layout change packages, or event templates" to achieve low-cost iteration.

[0078] S5, Cross-Agent Knowledge Distillation and Shared Memory: Establish a cross-agent knowledge sharing mechanism to write high-quality collaborative experiences, key decision fragments, and violation or risk handling cases into a shared memory bank. Through knowledge distillation, effective collaborative patterns in the group strategy are synchronized to various vehicle and node agents, enabling newly added vehicles or new customs area deployments to quickly acquire customs clearance collaboration capabilities, thereby improving group consistency and portability.

[0129] To demonstrate the effectiveness of the above embodiments, the following embodiments were verified using a public dataset. Specifically, the public dataset used in this experiment is Amazon LMRRC, which comes from real last-mile delivery operations and contains 9,184 historical delivery routes collected from five large metropolitan areas. It provides route-level, station-level, and package-level features, such as route attributes, station service information, and package statistics. It also provides the travel time between stations and the actual stop order, which facilitates the evaluation of the feasibility, cost, and timeliness of route planning and scheduling strategies under real operational data distribution. To meet the requirements of public use and privacy protection, the dataset does not contain personally identifiable information, route and package identifiers have been re-randomized, and related location data has been anonymized or obfuscated.

[0130] The experimental results in Table 1 show that, compared with local optimization, heuristic routing, strategy optimization, and tabu search, this invention achieves the highest constraint satisfaction rate (99.0%) and on-time rate (95.4%) under the condition of deployable computation time (0.95s). Furthermore, it reduces the average route cost to 0.88 and the number of devices used to 10.4. This demonstrates that in customs scenarios with strong constraints such as passage permissions, checkpoint strategies, and time windows, and under the requirement of cross-regional relay collaboration, it can output a more stable and executable scheduling scheme and effectively reduce queuing and waiting costs. The invention avoids the risk of timeouts; at the same time, compared with tabu search, the invention achieves higher feasibility and timeliness, as well as lower cost and resource consumption, while significantly reducing the solution time (3.60s→0.95s). This shows that it not only improves the quality of the solution, but is also more suitable for online replanning under high-frequency rolling scheduling and sudden disturbances at ports, such as congestion, temporary inspections, and equipment failures. In summary, this invention verifies that it can take into account "compliance and controllability, timeliness and efficiency, resource saving and real-time response" in customs clearance operations with continuously changing rules and environments, forming a scalable collaborative decision-making capability for actual port deployment.
