SIMULATION OF OPERATION IN THE RECEPTION SIDINGS OF MARSHALLING YARDS

The problem is one of a two-stage queuing system, at reception sidings and for the humping process. It is handled by computer simulation, with random train arrivals, following an "Erlang K" distribution. The computer program comprises some 900 FORTRAN instructions, and the time required for 30,000 trains is one minute on an IBM 370/165 computer. The results are shown in 7 graphs, which give correlation coefficients between the operating characteristics, such as the operating process and the number of reception sidings, processing time, minimum occupation time, and number of trains per day.
