Research On The Pricing Method Of Railway Vehicle Transportation Based On System Dynamics

The rapid development of Chinese automobile industry has brought the vast market of automobile logistics,and promoted the rise of the third party logistics enterprises.In China,highway occupies the leading position of vehicle logistics with its own advantages of short,frequency and fast.According to the nineteen spirit,China Railway Corporation has formulated the strategic goal of "traffic power and railway first",which has brought the development prospect for the railway into the vehicle logistics market.Based on the background of railway vehicle logistics,this paper investigated the operation mode,transport capacity and logistics nodes of China Railway special cargo company.Combined with the characteristics of railway vehicle logistics,this paper compared the transportation characteristics of highways,railways and waterways,and analyzes the advantages and disadvantages of railway development of automobile logistics with SWOT analysis method.In order to establish the pricing mechanism of railway vehicle transportation,this article according to the system dynamics method seted the railway vehicle transportation pricing from one station to another station as the research object.The paper divids the boundary of the system,and analyzed the price level of the railway car transportation by a combination of quantitative and qualitative analysis methods.It builded the equation of state and corresponding rate equations.For example,transport profits,the number of JSQ cars,the demand for vehicle transportation and so on.Using the concept of system dynamics,it drawed and studied the dynamic behavior flow chart of railway vehicle transportation.Through the adjustment and Simulation of some auxiliary quantities,this paper analyzed and verified the validity of the model,so as to provide a scientific and reasonable price decision basis for logistics enterprises.
