A Steady State Analysis for Yard Performances

Lookup NU author(s): Dr Marin Marinov, Philip Mortimer, Dr Tom ZunderORCiD, Dr Dewan Islam



Yards play an important role for the quality of rail freight services. These facilities function as reassembly hubs in rail freight networks and incorporate a significant amount of static and dynamic resources. From the customer’s perspective yards are thought of as an element that adds a little value to the final product. Form the rail operator’s perspective yards are seen as a main source of delay and loss of business. Therefore, running yards inefficiently is not acceptable. In this paper, a double-ended flat-shunted yard has been studied by G/G/m queues. The results obtained demonstrate significantly low utilisation levels of the yard subsystems in question. Therefore, possible improvements through changes in traffic rules and production schemes are discussed.
