Scheduling Model of Multiple Units on Intercity Railway

Abstract:

By analyzing the mathematics scheduling modal of Multiple Units(MU)，the paper parses concerned basic concepts dealing with the scheduling of MU.According to the character of scheduling of MU on Intercity Railway (IR),the scheduling problem is divided into two subproblems:subroutingsmaking and routingbuilding based on the subroutings.According to an algorithm combined with compact assign and matrix,and operational time strategy designed to optimize the routings in terms of balances,the paper constitutes a modal of the periodic scheduling of MU on IR,and gives an example of HuNing mainline on the foundation of latest train graph in April of 2009 to explain the new method.Results indicate the method adapts to the actual situation of IR.The use of the model and algorithm provides a good reference for scheduling MU.
