Method of Determining the Minimum Required Number of Sorting Tracks, Depending on the Length of the Group of Wagons

Abstract

This article, based on the study of local and foreign experience, identifies the need to seek comprehensive solutions for the effective organization of the wagon-flows in JSC “Uzbekistan Railways”. Based on the processing of statistical data, it was determined that the length of a group of wagons in a one direction multi-group train is subject to the law “Erlang”. Based on the use of Fibonacci numbers to search for the best scheme for the formation of multi-group trains, the method of determining the minimum required number of sorting tracks depending on the length of the group of wagons has been improved. As a result of the application of this method by JSC “Uzbekistan Railways” at station “Chukursay”, the cycle time of the sorting hill was reduced by 12%, the time spent on sorting of transit trains was reduced by 5% and the processing capacity of the sorting hill was increased by 14%.
