The level of rail container transport, the most common and perspective type of freight transportation is also low compared to European countries. Therefore, the main idea of the article is to justify the need for the introduction of fundamentally new transport technologies that will help reduce or eliminate the problems of freight transport, and so the article is relevance. The possibility of using magnetic technologies that exclude contact of a vehicle with a road structure, for freight transportation is investigated. The authors consider the main structural elements, functions and possible options of the magnetic levitation transport system of freight transport. The practical value of the work is that the use of magnetic levitation container platforms will significantly increase the intensity and speed of the conveyor sending of each container with a decrease in energy consumption, which will significantly affect the improvement of cargo logistics. The main results of the work: the conceptual bases of construction of unmanned magnetic levitation vehicles and the main systems of their infrastructure are formulated, it is shown that the implementation of the function of drone for the vehicle is possible only if permanent levitation in all sections of the freight transportation will be provided.","PeriodicalId":33465,"journal":{"name":"Zbirnik naukovikh prats'' Derzhavnogo universitetu infrastrukturi ta tekhnologii seriia Transportni sistemi i tekhnologiyi","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-12-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46074957","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In order to adapt the hopper car for transportation on railway ferries in international traffic, it is proposed to install on its pivot beams knots for fastening chain ties. Determination of the dynamic load of the load-bearing structure of the hopper car was performed by mathematical modeling. The case of the on-board rocking of the railway ferry is taken into account. The solution of the mathematical model is implemented in the MathCad software package. The total amount of acceleration acting on the supporting structure of the hopper car was 2.4 m/s2 (0.24 g). The obtained value of acceleration is taken into account when calculating the strength of the load-bearing structure of the hopper car. The calculation was performed by the finite element method in the SolidWorks Simulation software package. The results of the calculations established that the maximum equivalent stresses are 312.3 MPa and occur in the node for fixing. However, they do not exceed the allowable values. The conducted researches will promote increase of efficiency of operation of hopper cars, and also creation of developments concerning designing of their perspective designs.","PeriodicalId":33465,"journal":{"name":"Zbirnik naukovikh prats'' Derzhavnogo universitetu infrastrukturi ta tekhnologii seriia Transportni sistemi i tekhnologiyi","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-12-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"69984234","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This is especially true of severe operational damage arising from the destruction of parts and accompanied by a violation of the synchronization of their reciprocating and rotational motion. On the other hand, the performed study shows that the causes of malfunctions and failures of electric motors can also be determined by logical and probabilistic methods, including on the basis of fault tree analysis involving the results of research on various faults. By structuring the signs of failures, a failure tree was compiled that logically describes the cause-and-effect relationships between the failure event and the initial damage that caused it separately for each of the failure modes selected for analysis associated with severe damage to the electric motors of the type under study. As a result of using the fault tree in practice, it is possible to determine the causes of failure of electric motors and electric motors with automatic control systems with sufficient reliability and minimal time.","PeriodicalId":33465,"journal":{"name":"Zbirnik naukovikh prats'' Derzhavnogo universitetu infrastrukturi ta tekhnologii seriia Transportni sistemi i tekhnologiyi","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-12-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46517138","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For the formation of theoretical foundations and effective mechanisms of port management, it is important not only to analyze the current state of transport networks and port systems, individual ports and their infrastructure, but also to analyze the processes of the emergence, formation, functioning and development of ports. The results of such a retrospective review from the perspective of a critical analysis of the relevant historical experience contribute to the formation of a systemic view of the prospects for the development of domestic ports. After all, prospective and retrospective analyzes are closely related. Without a retrospective analysis, it is impossible to objectively understand the prospects of the movement of this or that port on the way of its further development. The paper examines the management systems that operated during the period of Ukraine's independence in its ports, analyzes the current status of domestic ports, and also conducts an analysis of existing approaches to the periodization of port development processes in the world.

Chronic underfunding of the activities of scientific institutions, the implementation of scientific research and scientific and technical development of institutions of higher education, academies, institutes, individual scientific programs and granted grants has led to many negative trends in the development of science in Ukraine and bad consequences. Therefore, in the post-war period, when restoring and reforming the infrastructure of Ukraine, it is necessary to update and improve the system of financial support for scientific research. This will serve as the basis for the further development of science in the country.The article analyzes the financial support of scientific research for 2020-2022. The decline of Ukrainian science, the activity of scientific institutions and organizations in living conditions is due to significant underfunding of their work. Spending on scientific research and development in Ukraine has decreased by 40% over the past 11 years. Measured in US dollars, the share of spending on scientific research and development in GDP has almost halved (by 46%) from 0.75% in 2010. to 0.41% by 2020Chronic underfunding has led to a number of negative phenomena in the development of science, the main of which are the following: a decrease in the motivation of scientific workers, a very low level of average costs per employee (9.37 thousand US dollars in 2020 in Ukraine against 300 thousand dollars in the USA, $250,000 in Germany, $200,000 in France, etc.), a reduction in the number of scientific researchers, an increase in the departure of scientific personnel abroad, a low level of prestige and the image of scientific activity, a weak influx of young people into science etc.Thus, science in Ukraine is in a state of deep crisis, so the first step in thepost-war period is to significantly improve the funding of scientific research several times by increasing the share of GDP expenditures to 1.7%, as it is legally established in Ukraine. In the future, taking into account the rise of the country's economy,bring this indicator to the level of 2-3% of GDP, which is valid in EU countries.This norm is justified and successfully used in EU countries,and it is necessary to reach its level in Ukraine. This is a minimum, because the GDP of Ukraine is much lowerthan the developed countries of Europe. In addition, taking into account that Ukraine received the status of a candidate for EU membership, it is necessary that the norms of funding of science be approximated to the norms of European Union.","PeriodicalId":33465,"journal":{"name":"Zbirnik naukovikh prats'' Derzhavnogo universitetu infrastrukturi ta tekhnologii seriia Transportni sistemi i tekhnologiyi","volume":"24 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-12-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72573623","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is shown that crises constantly accompany economic activity and, first, are manifested in a decrease in production volumes, deterioration of key indicators of financial and economic activity and provoke the emergence of various types of deficit conditions or interruptions in the functioning of enterprises. The withdrawal of the production and economic system from the crisis is possible due to changes in the economic process due to the creationand implementation of innovations.The change of approaches to the scientific understanding of the impact of crises on the development of production and economic systems is considered. A critical analysis of two classifications of crises (unexpected (random) and expected (regular), managed and unmanaged) is performed. An analysis of the crises in Ukraine, the \"gasoline crisis\", and the war as a manifestation of the crisis is carried out. It is shown that the way out of the crisis requires appropriate managerial decisions, which must be innovative in nature. They can be, firstly, organizational, and economic, technical, technological, managerial, etc., and secondly, timely.The gradual exhaustion of the potential of any idea and the innovation based on it isan objective process and is caused by moral wear. This determines the need to reserve funds from current income to prevent crises, to look for other sources of financing innovations and to constantly be concerned with the birth of new ideas for the development of theenterprise. A model definition of the term of the onset of the limit of the effectiveness of the innovation is proposed for forecasting the next crises.The relationship between crisis phenomena and innovations in the transport sector is considered, and the manifestations of the crisis state in the functioning of various types of transport are highlighted.

The legal regulation of lease accounting in Ukraine is carried out by a number of national regulations and international accounting standards. Each legislative document reveals the concept of lease in accordance with the scope of its application. Having considered the content of lease relations, one can observe certain contradictions of their economic and legal essence. For the needs of accounting, the regulatory framework is National Accounting Standard (NAS) 14, according to which rent and leasing are equivalent concepts, but this equality is incorrect from a legal point of view. Tax legislation also identifies these concepts. The study of the classification of lease (leasing) operations allowed to draw conclusions about the similarity of the options and features proposed by domestic and foreign scientists. The disadvantages of the studied classifications are insignificant changes in definitions, the formation of distribution by features that do not meet the needs of accounting. For a correct understanding of the classification of lease transactions, it is necessary to be guided by the need to reflect the lease in the accounting accounts for the possibility of drawing up reliable financial and management reports of the enterprise.Division of lease by periodicity, peculiarities of use, object of property are not essential for accounting and management accounting at the enterprise. To improve the reliability and accuracy of financial and management reporting, it is necessary to study in depth the essence of lease transactions and their reflection in accounting. Proposalsfor improving existing classifications are presented, which will contribute to the effective organization of accounting, control and analysis of lease operations at the enterprise. The developments can be used in the theoretical substantiation and practical development of the methodology for classification of lease (leasing) operations at Ukrainian enterprises.","PeriodicalId":33465,"journal":{"name":"Zbirnik naukovikh prats'' Derzhavnogo universitetu infrastrukturi ta tekhnologii seriia Transportni sistemi i tekhnologiyi","volume":"29 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-12-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87217259","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
