Study On The Train Scheme For Passenger Dedicated Line

The passenger trains plan is the core of the passenger transportation organization. A reasonable plan is advantageous in raising the passenger transportation special line's market share, and it's also advantageous in improving railway operational efficiency. Nowadays, our country's passenger transportation special line had the large-scale construction, the related line began operation, but there is not reference examples for making passenger trains plan, the study of passenger trains plan isn't systemic, so there are still many problems to be further studied about the passenger trains plan.At first, this thesis analyzes the characteristics of the passenger trains plan at home and abroad; then analyzes from elements, influence factors and the principle of making passenger trains plan, it analyzes the influence of the stop time and stop frequency to the passenger trains plan, presents the function of the stop time and the principle of defining the maximum number of stop frequency; finally, the thesis establishes the integrated model. The objective function is to make the biggest railway operating income and to make the smallest of the passenger travelling cost, and the constraints are the demand of passengers, the station ability and the stop frequency of the train. It is a Multi-objective nonlinear programming problem, and it's variables are the train operation section, the train species, the train stop scheme and the results of passenger flow assignment. This model is very complicated to solve, after dividing into steps and simplifying the model, we get a multi-objective 0-1 linear programming model. By introducing some relevant parameters and unifying the unit of the objective functions, the multi-objective linear programming model is converted into a single objective programming problem. At last, the thesis solves it with implicit enumeration method, verifies the feasibility of solving method, presents the passenger trains plan of Zheng Wu.
