The Technology Research Of The Passenger Dedicated Line Dispatching Optimization Based On The Particle Swarm Algorithm

The main railway lines of our country will implement "the new railway line only for passenger traffic and the existing railway line for commodity traffic", according to the long-term planning of China railway construction by 2020. This paper will focus on the traffic organization model optimization of transport organization only when passenger trains can be found on Passenger Dedicated Line.At the beginning, the operation scheduling setups of Passenger Dedicated Line is introduced, and then, the transport business of operation scheduling will be analyzed from the basic plan, implementation plan and operation plan, for three levels. And more attentions will be paid on the adjustment of train traveling and its route, which is the theory of the relevant mathematical model in the later chapter.What's more, combining the adjustment of the train operation, which is the daily work contents of dispatchers, we will pay more attentions to the mathematical model of the train operation adjustment in the fourth chapter, which is solved by the particle swarm algorithm. In addition, considering the characteristics of centralized dispatching, the paper will also discuss the mathematical model of departure line distribution in the fifth chapter, the steps and some key points of the solving process by discrete particle swarm algorithm.The main content as follows:1. First, the operation scheduling setups of Passenger Dedicated Line is introduced,And then, the transport business of operation scheduling will be analyzed from the basic plan, implementation plan and operation plan, for three levels;2. Select the dispatching command work and the adjustment of train operation, the key points of the train operation scheduling. considering the related factors, we provide the theoretical foundation for the mathematical modeling;3. Considering the various limit of the train operation adjustment, we establish the mathematical model of the train operation automatically adjust, in order to reduce the total time delays and the number of behind schedule, and try to put the end to the complex optimization problem by using Particle Swarm Algorithm. At the same time, we will talk about the design process, which includes the calculate method, the steps and so on, further more, the multiple key points will be analyzed in detail in the end; 4. Considering the operation interference of railway station, the convenience for passengers and use the departure line balanced, we will establish the mathematical model of the reasonable use the railway station departure lines, and then, try to solve the problem by using the Binary Discrete Particle Swarm Algorithm combine with the feature of variables, what's more, the design process, the calculation method and the example analysis will be given at end of the paper, providing the reference for further research.The research content can not only help understand dispatchers' job content, but also do a good favor to improve the level of dispatching automation and decision-making intelligent.
