Simulation Modeling of Logistics Supply Chain Based on AnyLogic

In response to the complexity of the pharmacy supply chain network, AnyLogic software is utilized to conduct simulation analysis on this supply chain network. The relationships among the main warehouse, regional warehouses, and stores are connected through agents and flowcharts, and the final results are intuitively displayed in GIS. The product flow and layout of the regional warehouses are analyzed, and the logistics costs in the initial state are statistically calculated. Then, AnyLogic is used again for simulation to verify the optimization results.
