Simulation of container operations in the marshaling yard – case study: Aprin station

In this project, an attempt has been made to investigate the loading/unloading operations for container loads on a at the Aprin station with a simulation approach. Simulation is an approximate imitation of the operation of a process or system whose performance is examined over time. In this study, Aprin station was selected as the largest railway station for container transport in Iran. To find out the detailed operation in this station, a field visit was performed and the details of the operation and the probability function of activity times were obtained. Based on the field visit, a discrete event simulation model was developed and Python language was used to implement it. The results of comparing the actual data and the output of the simulation model show that with a probability of more than 99%, the simulation model describes the reality.
