Assessing the transit capacity of port shunting yards through discrete simulation

摘要

The port shunting yards are developed inside the area of the ports. The mainactivities are to receive the freight trains from the hinterland, to shunt the freight wagonsaccording to their final destinations from the area of the port, to receive the wagons frommaritime terminals, to accumulate wagons according to their destination, and to departthe freight train to the hinterland. So, it is important for port administration to have goodmethods to evaluate the transit capacity of port shunting yards. A feasible method is touse the discrete simulation model. In our paper, we develop one of this taking intoconsideration the input flow characteristics of freight trains from land network, the inputflow characteristics of freight wagons from maritime terminals, the number of tracks in aport railway station, the technology used for separation of freight wagons on destinations(inside the port or from hinterland), and the duration of technological processes. From theresults, we extract the values of trains and wagon sets that transit through the main areasof the railway station (Receiving Tracks, Hump(s) and Departure Tracks).
