Railway Freight Dynamic Pricing Method Based on System Dynamics

摘要

In order to make railway freight transport enterprises better adapt to freight rate reform and improve their competitiveness in the transportation market, it is necessary to establish a dynamic pricing method reasonably. This paper first analyzes the internal and external factors affecting the freight rate of railway freight and the advantages, disadvantages, and applicability of the existing pricing theory methods. Then, because of the complex nonlinear feedback characteristics of the railway freight pricing system, system dynamics method is used to analyze and quantify the internal and external factors affecting the freight rate of railway freight and establish the system dynamics model between freight rate and those related factors. Finally, the simulation is carried out by using VENSIM PLE software, and the changes of the railway freight rate with the related factors is calculated by the example. It verifies the validity of the model and its controllability and flexibility.
