Planning rolling stock operation in international communications with modern requirements to cargo transportation technology

Abstract

Introduction. The relevance of the research carried out is justified by the need to plan performance indicators of rolling stock in the context of changes in the technology of cargo transportation in international traffic when implementing the Draft Order of the Ministry of Transport of the Russian Federation. An obligatory element in the technology of cargo transportation is the re-coupling of a semi-trailer or reloading of cargo. In practice, there are additional costs for the transportation of goods due to the significant waiting time for interchange due to the deviation of the time of arrival of rolling stock transporting goods in international traffic to the interchange point in accordance with the contract from the planned time of arrival at the interchange point. Today, there is no methodology for planning the operation of rolling stock of road transport in international traffic that takes into account modern requirements for the technology of cargo transportation in terms of eliminating waiting time at the point of transfer or reloading of cargo. The purpose of this article is to develop an algorithm for a planning methodology based on the mathematical model of the functioning of rolling stock in international traffic, created for the first time by the authors, taking into account modern requirements for cargo transportation technology.Materials and methods. To achieve the purpose of the study, the scientific foundations of current planning of the work of a motor transport enterprise are applied. The development of a mathematical model for the functioning of rolling stock in international traffic was carried out on the basis of the criterion - minimum transportation costs, taking into account the duration of technological operations, including waiting time at the point of transfer or reloading of cargo. The systematic nature of the study lies in the fact that the properties of cargo transportation are manifested in relation to rolling stock and depend not only on the properties of the cargo, but also on transportation technology, the time of completion of the transport process, which are established in the contract and affect the performance of the rolling stock.Results. The use of planning methodology for the practice of functioning of rolling stock in international traffic, taking into account modern requirements for cargo transportation technology, was carried out using the example of transporting a disassembled hydraulic vulcanization press. Software and mathematics have been developed to calculate costs.Conclusions. A methodology for planning the functioning of rolling stock in international traffic has been developed, taking into account modern requirements for the technology of cargo transportation based on the created mathematical model, using regulatory requirements for the transportation of goods in international traffic and promising theoretical studies. Practical implementation is presented using the example of a DAF XF 480 FT truck tractor with a Kogel S24-1 semi-trailer.
