Item Optimization of Track Distribution of Industrial Railway Stations between Car Designations(Dnipro University of Technology, Dnipro, Ukraine, 2023) Nurzhaubayev, Meiram; Grevtsov, Serhii; Korobiova, Ruslana H.; Manafov, Elshan; Abdukarimov, Sadratdin; Arpabekov, MuratbekENG: Purpose. To improve the method for distributing the tracks of industrial railway stations for the accumulation of car groups between separate assignments. The optimization problem is to find such a distribution of classification work between the industrial marshalling yard and freight stations, as well as such a distribution of marshalling yard tracks between individual destinations, which ensures the minimum time expenditures on shunting work. Methodology. The studies were carried out using the methods of the theory of railway operation, simulation modeling and dynamic programming. Findings. The optimization problem of distribution of sorting work between the marshalling yard and freight stations of an industrial enterprise, as well as searching for such a distribution of marshalling yard tracks between individual destinations, which ensures the minimum time expenditures for shunting work, has been solved. Originality. The paper proposes a method for formalizing and solving the problem of distributing the tracks of industrial railway stations for the accumulation of car groups between individual destinations as a dynamic programming problem. Unlike the existing methods, where the number of tracks is considered as a constraint, in the proposed method, the number of tracks is an objective function argument of minimizing the duration of shunting operations, which improves the quality of the solutions obtained. Practical value. The method proposed in the paper, due to the rational distribution of the existing track arrangement of railway stations, makes it possible to reduce the time expenditures on the making- and breaking-up the trains and shunting transfers and, due to this, increase the carrying capacity of the stations, as well as reduce the cost of production of enterprises.Item Сompetitiveness Assessment of the Railway Network of Kazakhstan in the Performance of Transit Container Transportation(Dnipro University of Technology, Dnipro, Ukraine, 2023) Tilemissova, Aigul; Kozachenko, Dmytro M.; Vernyhora, Roman V.; Izteleuova, Maral; Arpabekov, MuratbekENG: Purpose. To improve the methods for assessing the routes of transportation of containers by transit railway administrations. Methodology. The results of the presented scientific research were obtained on the basis of general methods of cognition such as abstract-logical analysis, systematization, the method of theoretical generalization, as well as on the basis of special methods of economic and mathematical modeling, the theory of railway operation and transport geography. Findings. In the course of the study, an analysis was made of the transport network of the Eurasian continent as a whole and the railway transport network of Kazakhstan, as part of it, in particular. An assessment was made of the socioeconomic development of the regions, transportation between which can potentially be carried out through the territory of Kazakhstan. Indicators of the duration and cost of shipping containers by sea and rail between East Asia and Europe have been established. An assessment of the competitive ness of container transportation routes passing through the territory of Kazakhstan in comparison with alternative routes was made. Originality. In this paper, the method for estimating the routes of transportation of containers by transit railway administrations has been improved. Unlike existing methods, the assessment of the duration of transportation is carried out throughout the entire length of transportation “from door to door”. Also, the paper proposes to evaluate the effectiveness of railway routes, taking into account the service of the entire territory through which they pass, and not just the starting and ending points. Practical value. The results of the research allow railway administrations to improve the efficiency of planning the development of transit container traffic on different routes. The regions for which the railways of Kazakhstan can compete with maritime trans port both in terms of price and in terms of the speed of transportation for the entire container traffic, as well as regions for which competition can be carried out only for the market share of transportation in containers of valuable and perishable goods, have been established.
