Research On The Pricing Of Freight Options Of Discrete Railway Bulk Cargo

In order to reduce carbon emissions,reduce environmental pollution and improve air quality,national vigorously promote the bulk transport of goods "revolution of iron,revolution of water" as the main direction,improve the comprehensive transportation network,to improve the level of transport organization,reduce road traffic,increasing railway traffic volume,speed up the construction of modern comprehensive transportation system.Therefore,the railway corporation also actively implements the railway freight reform,but in the process of promoting the railway freight reform,the freight rate is inevitable.In the process of accelerating the reform of railway bulk freight,how to design an effective freight rate system,play the role of price leverage,construct a price mechanism that helps the railway system to improve the efficiency of transportation and market competitiveness,expand the market share of railway bulk freight,and improve its operating status,is of great theoretical and practical significance.This paper focuses on the pricing of freight options for railway bulk cargo,and the main research contents and results are as follows:(1)Systematic summary of railway freight pricing method,freight option and Stackelberg game related research,summarize the shortcomings of the existing pricing method,clarify the concept of option,and determine the type of game.(2)The concept of option is introduced,the railway freight option is defined,and the Stackelberg game model of railway freight pricing based on option theory is established to discuss the optimal decision of contract customer and the optimal pricing decision of railway freight option.(3)This paper designs the execution process of discrete railway bulk freight options,and determines the types of options.Based on Heston model,the paper constructs the discrete railway bulk freight options pricing model by optimizing its parameters with Beetle Antennae Search Algorithm,and calculates the option price,which provides theoretical support for the railway transportation enterprises to carry out option pricing.
