Research on High-Speed Railway Freight Train Organization Method considering Different Transportation Product Demands

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.

Optimization of High-Speed Rail Express Transportation Plan Considering Products’ Variable Time Requirements

“…Existing research on high-speed rail express transport is more concentrated, mainly for freight train organization optimization, but at present, freight electric multiple units (EMU) are not widely applied in the world, one reason for which is that such transportation modes will occupy much of the line capacity and thus affect the passenger transportation service. Considering the above situation, some scholars have shifted their research to the piggyback transport mode, but there are fewer related studies [7], and the existing research is mainly limited to single transport organization mode [18]. In this paper, the piggyback transport mode and the high-speed railway confirmation train mode are included in the scope of research so that the optimization results have some practical significance.…”

The Role of EU Transport Market Liberalization in Shaping Directions of Rail Energy Consumption Rationalization in Relation to the Export of Goods: The Case of Poland

“…Furthermore, rail freight transport is the cornerstone of economic stability and growth, providing a sustainable and efficient way to transport goods [1]. It serves entities by streamlining goods flows, reducing delivery times, and enhancing service quality [5][6][7]. The structure of rail freight transport is likely to alter due to global trends such as energy intensity reduction, decarbonization, and the circular economy, which may restrict the transport of some items such as coal and oil [6].…”

Logistics hub location for high-speed rail freight transport with road-rail intermodal transport network

“…Considering the variation of the demand of China's express market in the future, the method of "three-stage" forecasting of HSR express cargo flow OD is used by Chen et al to forecast the demand for HSR express between cities [7]. Yu et al, Yu et al and Li et al studied the highspeed rail freight train transport organization under different scenarios [8][9][10], such as sustainable transport, considering different transportation product demands and coordinating with passenger transport. Chen et al studied the integrated optimization of the selection of transfer stations and train schedule in the HSR express network [11].…”
