Improvement of the technology of accelerated passage of low-capacity car traffic on the basis of scheduling of grouped trains of operational purpose

Forecasting the estimated time of arrival for a cargo dispatch delivered by a freight train along a railway section

“…Comparative analysis of regression methods to predict the time that it takes for a freight train to travel along a railroad section is given in Table 1. Table 1 Comparative analysis of regression methods to predict the time that it takes for a freight train to travel along a railroad section Based on the specified indicators (Table 1), the worst among the selected methods has proven to be a multiple linear regression model [22], which confirms the above conclusions regarding dependence (1), which describes complex non-linear processes of section operation. The most appropriate method was a regression model based on the artificial neural network, a multi-layer perceptron, MLP.…”

“…The market of transport services increasingly faces the need for personalized mobility and logistics solutions that ensure lower risks in the transportation process. As practice shows, the technological process of cargo transportation by railroads has a lot of serious drawbacks, the main of which is the lack of predictability of the duration of operations execution in the process of transportation [1]. The high degree of uncertainty in the execution of a transportation process is particularly characteristic of the railroad system of Ukraine (AT "Ukrzaliznytsya"), which belongs to railroads with a system of trains traffic not complying with a departure schedule.…”

Improvement of efficiency in the organization of transfer trains at developed railway nodes by implementing a "flexible model"

“…A discrete-event simulation (DES) will be the form of imitation modeling because the process of arrival of wagons to accumulation points, formation, dispatch and motion along the sections by transfer trains can be represented as a discrete-event one. This argument for railroad technological processes was substantiated in detail in papers [2,4,5].…”

“…However, these models cannot be used to assess the effectiveness of functioning of marshalling parks where wagons are accumulated to the standard of a train. Adjusting the process of forming grouped trains to scheduled traffic, by using appropriate optimization models, makes it possible to accelerate the delivery of cargoes by railroad transport [5]; however, there is the unresolved issue on matching the dispatch of transfer trains at developed rail nodes with heavy passenger traffic.…”

Methodology of costs assessment for customer transportation service of small perishable cargoes

“…Effective management of the transportation process is of great importance (Karnaukh et al, 2018;Rehman et al, 2016;Sandybayev, 2018) while ensuring the most rational use of the rolling stock and reducing the transportation costs and minimising environmental pollution. The rational organisation of any technological process at cargo delivery leads to reducing the delivery costs (Nel and Badenhorst-Weiss, 2012;Shramenko, 2015;Muzylyov et al, 2016;Prokhorchenko et al, 2019) as well as reaching the synergetic effect (Shramenko, 2016).…”
