Optimization of hump and assemble sequence of trains in railway marshalling yard
摘要
Abstract
Daily operation of marshalling yard mainly focuses on optimizing the hump sequence of arrival trains and assemble sequence of departure trains.Based on the wagon-flow allocation plan, this paper presents two sequencing models of hump and assemble,such as the sequencing model with one hump engine and one-yard engine,as well as a general model with multi-engines,which can be improved to take the optimization of technical inspection sequence of trains into considera-tion.At last,numerical examples are proposed to verify those models.The calculation results of different numbers of shunting engines show that the efficiency of parallel hump process does not always better than single hump process and the hump sequence and assemble sequence are inter-acted,and the capacities of two parts should be coordinated with each other.The efforts on the efficiency of the whole dispatching system appears insignificant,if only the capacity of the hump side or assemble side is increased.关键词
