چکیده مقاله
This study simulates an underground freight transport system inspired by Switzerland's Cargo Sous Terrain project, using a combination of agent based modeling and discrete event simulation The primary objective is to evaluate system performance under normal and failure free conditions based on projected demand patterns In the model, stations and vehicles are treated as independent agents that interact within the network Two key performance measures are considered: the length of queues at stations and the time that stations remain occupied The simulation results reveal that some busy stations experience persistent congestion, which restricts the efficiency of the entire system A redesign strategy, focused on introducing a double track configuration at these critical stations, is shown to alleviate bottlenecks, reduce waiting times, and enhance responsiveness to demand This adjustment not only improves throughput and reliability but also demonstrates the adaptability of the system to fluctuating traffic conditions Overall, the approach highlights the value of combining agent based modeling and discrete event simulation for analyzing underground logistics networks and guiding future development
