The Composition and Characteristic Analysis of Logistics Capability in Multimedia Supply Chain via Reinforcement Learning

As the supply chain is growing exponentially owing to multimedia, the cost of logistics transportation has started to play a vital role in influencing the efficiency of the system. Conventional heuristic and evolutionary methods, including genetic algorithm (GA) and ant colony optimization (ACO), offer viable solutions to vehicle routing concerns; nevertheless, they experience difficulties in being flexible, efficient in computation, and sensitive to parameters in dynamic conditions. To overcome these limitations, this paper offers an adaptive Actor–Critic reinforcement learning system (ada-A2C) to optimize logistics distribution tracks. The model combines a convolutional encoder and a pointer network decoder to include attention mechanisms to capture spatial, temporal, and demand features of distribution nodes. Comparative experiments on synthetic datasets with 10, 20, and 50 nodes indicate that although Google OR-Tools can produce better quality paths in small-scale tasks, the proposed ada-A2C algorithm can converge much faster and possesses greater time efficiency, especially when the node size is larger. Moreover, the model does not need reconfiguration of the parameters many times, and it is adaptable to the input structures of variables. Cost analysis also proves that the ADA-A2C introduction lowers the overall logistics expenses by about forty percent, and the greatest effect was in the areas of manual labor, transportation, and inefficient inventory. A more precise definition of the audit control mechanism is as follows: (1) verification of each generated decision in real-time, which is constantly checked against capacity, distance and feasibility limitations; (2) dynamic penalty assignment, which is an evaluation that penalizes inefficient or infeasible routing behavior and is dynamically considered by the evaluating the agent to influence behavior toward optimal outcomes; and (3) feedback of corrective policies, which combines the assessments into the reinforcement learning process to steer the agent to good behaviors. This hierarchical process provides policy changes to be consistent and in line with the optimization goals during the training.
