Research on Operation Scheme of Shunting Locomotive in Railway Passenger Station

摘要

The key problem of operation dispatching during the process of drawing operative scheme for railway passenger station is the shunting locomotive operation scheme. Operation scheme of shunting locomotive for railway large-scale passenger station is a complicated system engineering that is influenced by multitudinous factors, such as the time of arriving and departing trains, technique and equipment conditions, number of trains and so on. To study on the operation scheme of shunting locomotive for railway passenger stations more comprehensively and reasonably, and balanced using of shunting locomotives as the objective, the optimization model was established based on the analysis of impacting factors on shunting locomotive scheduling, using stratified sequence theory, and algorithms were proposed to solve flexible flow shop scheduling problem and fixed jobs scheduling problem respectively, it can be solved easily by using Matlab. And optimization goal of shunting locomotive operation was reached by adjusting the passenger carriage of the earliest possible placed-in and the latest possible taken-out time for garage. Meanwhile, tight connecting time and the shortest idle running distances of shunting locomotive were also taken into consideration to meet the requirements of the practical operation where delayed trains and extra trains can depart on time. Finally, a case study is carried out to verify the validity, objectivity and applicability of this model and its optimization algorithm through calculated and analyzed practical data, from the test results, it is shown that the operation scheme of shunting locomotives is not only balance, but also the operation efficiency of shunting locomotives is efficient.
