Optimized Research For Utilization Of Receiving And Dispatching Tracks On The Railway Passenger Station

At present, China’s railway transportation is booming, and was followed by a sharp increase in railway passenger traffic, the current main through addition trains to alleviate the passenger pressure, therefore, the phenomenon of “multi-car little-line” has become increasingly prominent in the existing railway passenger station. Utilization of receiving and dispatching tracks on the railway passenger station is an important part of the station’s traffic technology work, the quality of its preparation for the comprehensive utilization of station equipment; safely and conveniently complete passenger transport task has a crucial role. Optimized research for utilization of receiving and dispatching tracks on the railway passenger station is to ensure uninterrupted receiving trains at the station, to avoid the train appeared delays, the greatest degree of efforts to improve the utilization of station equipment, to facilitate passenger travel, and strive to improve passenger transport service quality, safe and efficient completion of the railway transportation and production tasks at the case of the station equipment cannot be increased, but the number of trains are increasing. Therefore, when optimized for utilization of receiving and dispatching tracks, should give full consideration to various constraints of utilization of receiving and dispatching tracks, based on the balanced use of the device should also give full consideration to satisfy the various requirements of passenger travel.This article for the above, first of all, analysis the main work content of the passenger station, research the related elements of utilization of receiving and dispatching tracks, then to study various time elements of the track work at passenger station. Analysis the cross and ease of the driving work and shunting operation, and detailed analysis the occupancy turnout time, occupancy receiving and dispatching tracks time, occupancy receiving and dispatching tracks time interval time and train diagram buffering time.On this basis, describe the problem of utilization of receiving and dispatching tracks, then propose the followed basic principles and achieve goal when use the tracks. At the same time, analysis the various constraints of track occupied, the characteristics of passenger transportation and the features of passenger service quality. Using the multi-objective planning principles, to establish multi-objective optimization model, the two goals are full consideration to balance use of tracks and quality of passenger service.This articles using designed local optimization genetic algorithm, using C ++ programming, using the data of Lanzhou station during the Spring Festival for example, to solve the multi-objective programming model of utilization of receiving and dispatching tracks at passenger station. Prove the feasibility of the model and algorithm by analyzing the case results.
