An Optimal Design Of Rail Passenger Transport Products Under The Separation Of Passenger And Freight Lines

With the rapid development of China’s railway, the separation of passenger and freight lines will be real, and the railway capacity will been greatly improved. Especially with the passenger dedicated line, high-speed rail and intercity railway constructed and operation, the existing passenger transport products system has lagged behind the railway development. Meanwhile, the structure of the demand has changed according to the rapid development of economy, improved living standards, and increased trip times, which is more important in hierarchy and pointing. It is the premise of the separation of passenger and freight lines to passenger products design as the study object, considering the railway passenger transport network and passenger traffic demand alteration. It is also to analyze passenger hierarchy structure, design to optimize passenger transport products, the establishment of the product combinatorial optimization method with the market-oriented, and study the system of China’s passenger transport products, which has important practical and theoretical significance.First, through the analysis of the current state of domestic and international passenger transport products, this paper sum up the advantages of foreign passenger transport products, refine the technology development of China’s passenger product available, and point out that China’s passenger products structure development in the new situation, to determine rail social and economic combination to meet the needs of passengers travels level positioning, and make out the programmatic ideas and methods.Second, the passenger transport products connotation and development for starting to study the constituent elements. Analyze the current situation of railway passenger transport market, and establish product market positioning; Researching passenger demand status and passenger demand characteristics, it establish the hierarchy of passenger demand; And strengthen and improve the means of marketing and absorption of passenger feedback information, and to develop reasonable and effective fare mechanism, for passenger overall product design providing direction.Next, we make the design strategies derived from the form of the passenger products, and improve the design of existing products and increase the design of new products. Then design the some special passenger products, such as high-speed rail trains, tourist trains, military trains, inter-city trains and so on. So provide a variety of passenger transport products in order to meet the different needs of the passenger demand.Fourth, this paper put forward the corresponding strategies to serve the passenger transport products combinatorial design. From the passengers, railway department, and relations between products and demand to analyze the impact of rail passenger transport products combination. Then we establish a mathematic model, design optimal method, and provide the worth for the combinatorial design under the Separation of Passenger and Freight Lines.Finally, we study the passenger train plan on the basis of combinatorial optimization. Considering the line formation, passenger demand and number of supplied passenger trains, this paper establishes an optimal model, which deals with the train plan. It also designs the special genetic algorithm based on the group strategy between integer code and binary code. Then it is applied to the Hefei-Wuhan Intercity Railway line to verify the validity of the model and algorithm robustness.
