Abstract
The sustained and stable growth of China’s market economy promotes the continuous improvement of transportation demand and puts forward higher requirements for transportation products. At present, as a new product, high-speed rail freight has played an important role in cold chain logistics and high-value-added transportation, which is of great significance to effectively reduce the pollution caused by road transportation and further promote the sustainable development of economy and logistics industry. In the previous study, we studied the organization optimization method of high-speed rail freight train operation scheme and the compilation method of high-speed rail freight train diagram based on the overall demand of freight transportation but did not consider the influence of different high-speed rail freight transportation products on the organization scheme. Therefore, in order to ensure the sustainable development of high-speed rail freight business, based on the demand of high-speed freight products (the freight product for short in the following text), this paper focuses on the optimization method of high-speed rail freight train organization scheme considering different demands. A two-stage freight demand analysis method considering customers’ choice intention and actual supply capacity was designed, comprehensively considering the relationship between operation cost and income, and a model based on different products in order to meet the needs of large-scale case solving was established. In addition, a column generation algorithm was designed. The computational results are encouraging and demonstrate the effectiveness of the model and solution method.
Highlights
In recent years, with the sustained and stable development of China’s economy, China’s logistics industry has developed rapidly, and the demand for fast freight transportation has increased at a fast pace
High-speed rail freight is an important means to effectively meet the high-end logistics market, and the market demand will increase significantly year by year. e freight demand calculation method designed in this paper effectively considers the matching relationship between supply and demand
The demand-based organization scheme design effectively balances the relationship between cost and benefit
Summary
With the sustained and stable development of China’s economy, China’s logistics industry has developed rapidly, and the demand for fast freight transportation has increased at a fast pace. The high-speed rail freight business has been growing at a fast pace with an average annual compound growth rate of more than 30%. Erefore, the overall freight demand of high-speed rail freight should not be taken as the basis for making a train operation plan, but the demand of different transport products should be calculated so as to make a better transport organization plan. In order to fully meet the differentiated market demand, this paper designs the calculation method of demand sharing rate of the freight product, constructs a two-stage optimization method of high-speed rail freight train organization scheme considering the transportation demand of different products, and reveals the influence mechanism of transportation demand on transportation supply. An example is used to generate the high-speed railway express train operation plan
