Research On The Optimization Technology Of Technical Operation Plan For Large-scale Passenger Station

In recent years,with the rapid development of C hinese railway transportation,more and more passenger dedicated lines have been applied to large-scale passenger stations.However,such operating mode of mixing running involving multiple unit trains and normal passenger trains is commonly existed.Therefore,it is necessary for us to solve the problem that make high-level and efficient passenger station operating plans under the condition of mixing running involving multiple unit trains and normal passenger trains.Focusing on the problem above,this article introduced the facilities and the main technical operation processes of various passenger trains.Also,the theory of making technical operation plan including summarizing the goals as well as principles based on the contents and application of technical operation plan was deeply analyzed.In view of that,optimization method of making technical operation plan was studied systematically and explored deeply in the following aspects.(1)Mutual position of receiving-departure yard?passenger technology station and locomotive depot was introduced.Then,facilities and the main technical operation processes of various passenger trains were expounded.Besides,influence factors such as facilities occupancy and the coordinated optimization process of multiple unit trains and normal passenger trains were also analyzed systematically.(2)Based on theory of technical operation plan for large-scale passenger station,influence factors of route selection ? receiving-departure track occupancy and locomotive running process were analyzed,then the form of route conflicts and its untwine were also put forward.The conclusion that due to technical operation plan implementation,under the condition of station throat with tight capacity,not only should we consider coordinated optimization between track application and route selection,but also consider throat cutting and correlating facilities occupancy in the process of locomotive running was given.And then,under the consideration of locomotive running,optimization steps of making technical operation plan for large-scale passenger station were summarized.(3)Time range of locomotive running occupancy was described by analyzing technical operation processes as well as effec tiveness of locomotive running.Then the optimization model of making technical operation plan for large-scale passenger station was established by considering operating time range of shunting locomotive and route selection cooperative optimization.Therefore,according to the characteristics of such model,algorithm was given by using the principle of simulated annealing algorithm.(4)Nanchang railway station was taken as an example to further elaborate the model above.And the practicality and effectiveness of model as well as algorithm listed above were also verified.
