Forecasting material flows of modern logistics centres of railway freight stations exemplifi ed by Xi’an (the People’s Republic of China)

The purpose of the study is to create a more accurate material fl ow forecasting model of Xi’an freight railway station in China. The combined forecasting model is more validated for forecasting freight flows of regional logistics compared to three methods: grey forecasting, Markov chains, entropy weighting. Through the creation of the combined model, the grey forecasting method is combined with Markov chain correction, and the projected data is compared with the actual data to obtain higher accuracy of the forecasting model. A combined model using the grey forecasting method combined with Markov chain correction is created, with the forecast data compared with the actual data to obtain high accuracy of the forecasting model. The practical significance is that in the context of the present post-pandemic economic development, the logistics enterprises that do not operate in accordance with the modern logistics methods may be displaced by competitors. If the railway does not improve its logistics infrastructure, logistics equipment, railway logistics network platform, etc., it will lose out to other modes of transport. In order to meet the needs of logistics and improve the market competitiveness, the main indicator of a freight station is loading and logistics flow. Therefore, exact prediction of future changes in the logistics flow of a freight station can help to determine whether the station needs to be upgraded as a railway station or transformed into a certain type of a logistics centre.

Evaluation Methodology of the Railway Stations Using the AHP Method in the Transport Hubs from the Freight Transport Point of View

Currently, it is necessary to support not only public passenger transport at the expense of individual car transport but also to ensure the modal split of goods from road transport to railway transport. Moreover, it is important to modernize the railway infrastructure, especially hubs and other important railway stations in important settlements and big cities. Therefore, it is necessary to constantly invest in railway lines as well as railway stations. The contribution deals with the determination of the methodology for the evaluation of railway stations in freight transport based on current scientific publications and the AHP method. Its main goal is to determine the size of the peak on the network-railway station on the infrastructure manager’s railway network. One of the benefits is the subsequent determination of the next procedure from the given peak in terms of operation, considering the economic complexity of the entire procedure. The methodology is preceded by an extensive analysis of input data in Slovakia and abroad. This methodology defines the parameters or factors that influence decisions for a particular railway freight station. Subsequently, based on the proposed methodology, a practical application is also developed, within which four railway stations on the ŽSR network are evaluated. In a broader sense, the contribution also points to improving the quality of railway infrastructure in cities.

Comparative Analysis of the Factors Influencing Land Use Change for Emerging Industry and Traditional Industry: A Case Study of Shenzhen City, China

Analyzing the factors influencing emerging industry land use change is important for promoting industrial transformation and for upgrading and improving the level of intensive use of emerging industry land. In recent years, to solve the problem of land resource shortage and expansion space, Shenzhen has implemented a strategy of promoting urban development through technological innovation and has actively promoted the transformation of inefficient industrial land to emerging industry. This article introduces the development, land use types, and spatial distribution of Shenzhen’s emerging industries. Based on the logistic regression model, we analyze the differences between the factors influencing changes in land use for both emerging and traditional industry. The research results show that the distance from public roads, the distance from highways, the distance from railway freight stations, the proportion of secondary industry, and the proportion of tertiary industry are important explanatory variables for the two types of land use change. Traditional industrial land use is also affected by the land slope, the distance from ports, the population, and fixed asset investment. Emerging industry land use is also affected by the distance from the airport, the number of railway stations, the quality of the population, and innovation-driving forces. These results provide a reference for government to rationally plan emerging industry land and differentiated management of this, in order to fill the current research gap in the field of land use change, and to contribute to research revealing the mechanisms driving changes in emerging industrial land.

Carrying capacity and efficiency optimization model for freight train segment train

With economic expansion having moderated to a “new normal” pace, supply structure of goods and competition state of logistics market has undergone major changes. In order to respond to these changes actively, China Railway Corporation has launched railway express freight block trains to meet with customers’ demands. However, traditional operation conditions require every freight block train fully loaded to make best of transportation capacity. This has caused a series of problems to freight block trains, such as uncertain departure time, unstable running frequency and so on, which cannot meet with the customers’ basic requirements for goods transport and logistics. So it is an urgent task to study the suitable cars’ number and running frequency of railway express freight block trains so as to reduce customers’ costs and increase China Railway Corporation’s profits. Therefore, this paper analyzes the calculation method of customers’ generalized transportation cost and profits of running a railway express freight block train. Then, an optimization model for cars’ number and running frequency of freight block trains is proposed. The objective functions of this model are the minimum general transportation costs of customers and the maximum profits of China Railway Corporation. The model constraints are about transportation capacity, railway freight stations’ operating capacity and so on. Taking railway express freight block trains operated between Beijing and Shanghai as an example, the cars’ number and running frequency are calculated which can effectively reduce customers’ cost and increase China Railway Corporation’s profits. The results can prove the feasibility of the model proposed in this paper.

Research on freight business reorganisation for railway freight station hub in China

Freight business reorganisation (FBR) in railway freight station hub is researched on the basis of the idea of 'limited categories and limited directions'. First, according to the subordinate hierarchical decision-making relationship between railway departments and shippers, a bi-level programming model for FBR is constructed. The objective of upper level model is to minimise the total of freight turnover in the freight station hub and the dispersion of business, and minimising the transport cost for shippers is the goal of the lower level model. Then, reaction function between upper and lower decision variables is formatted and a heuristic algorithm to solve the model is developed. Finally, a numerical sample is designed to verify the feasibility of the model and the algorithm. The results show that the business dispersion in reorganised freight station decreased by 75.00%, freight turnover decreased by 18.21%, and the shippers' transport costs only increased by 9.40%.

Environmental Load Reduction Due to Modal Shift Resulting from Improvements to Railway Freight Stations

Intermodalism has become one of the most important ways of transporting freight with the development of social economy and industry. In order to correspond to the changing nature of freight transport and to improve railway transport effectively, it is essential to upgrade conventional freight stations to provide sophisticated facilities where loading/ unloading services are directly handled on siding tracks for arrival and departure. In this paper, we discuss the improvements of railway freight stations based on advantage analysis by comparing the conventional type with the new one. We then cover the development of a mode-share model using stochastic distribution of freight time value. Next, we estimate the modal shift of freight resulting from improvements to station facilities, and finally we investigate the related environmental effects such as reduction in CO2 emissions.
