Research On The Train Operation Scheme Of The Ordinary Railway Under Heavey Haul Transport Conditions

In the case of shortage of resources transportation in the "Xi San" area, to improve the capacity of railway transport, and to satisfy the development of national for energy, especially for the urgent need about coal, ore and other bulk commodities transportation, in some energy transportation corridors, not only need to satisfy the passenger demand along the way, but also need to complete the transport tasks which assigned by the railway authorities. With the development of the national economy, traffic demand is also rising year by year, under the market choice, the railway companies in order to obtain greater benefits to improve railway transmission capacity, so a reasonable optimization of passenger and freight train plan in the ordinary railway is necessary.Based on this background, this paper studied in the passenger and freight trains plan on the heavy-haul ordinary lines, and analyzed of the specific examples, draw the relevant conclusions.At first, this paper introduced the main factors of the ordinary railway line for passenger and cargo train plan, and to explore the relevant principles which passenger and freight train plan must take into account, so it done some groundwork for the follow-up studies.1. In the case of the quantities of cargo transportation in each year has been determined, established the largest train operating plan bi-level programming model mainly based on the freight trains on the ordinary line, and related the details of the calculation of the variables, the constraints, and the solution method in the model, and assumed the status of both passenger and freight transportation on a certain period railway, finally detailed the solution process.2. In the case of the passenger demand along the line has been satisfied while improving the quantities of the cargo transportation each year, established the model of operating train plans.and related the details of the calculation of the variables, the constraints, and the solution method in the model, and resolved the transportation status of both passenger and freight on a certain period railway, finally detailed the suggestions.
