    (PC TECHNOLOGY CENTER, 2023) Razghonov, Serhii; Lesnikova, Iryna; Kuznetsov, Vitalii M.; Kuzmenko, Albina; Khalipova, Nataliіa; Chernikov, Danylo; Zvonarova, Olha V.; Prokhorchenko, Halyna; Horulia, Mykola; Bekh, Petro V.
    ENG: Sustainable development has become the main focus of transport policy and planning around the world. One of the practical goals when performing multimodal transportation is the optimization of logistics costs. That is, the object of research is the process of multimodal transportation. Empirical research shows that the problem of optimization of transportation costs can be solved by different methods. But the result will be similar. In the given approach, only one component of the transportation process is subject to optimization, which is the overload time. The solutions are based on the method of mass service theory and the method based on fuzzy logic. With the help of these methods, based on practical data, time parameters were calculated that characterize overloading from railway transport to road transport. The application of the method of a weakly formalized process in relation to transport logistics was considered, taking into account not only quantitative estimates but also qualitative, vaguely defined criteria that do not lend themselves to formalization, and the relationships between them. The model was developed for further research of this process, prediction of its behavior, optimization of functioning. It is based on the technology of fuzzy sets. The results obtained using the agent model based on the mass service network and the model based on fuzzy logic differ within the permissible specified limits of no more than 5–7 %. The application of fuzzy logic in the logistics of multimodal transportation is relevant and gives the best results compared to traditional methods of the theory of mass service systems. The article includes comparisons that reflect the advantages of the proposed approach. The obtained results are of a practical nature and can be used to make a decision on choosing a route and/or when transferring from one mode of transport to another.

    Evaluation of Effectiveness of Piggyback Traffic within the National Network of International Transport Corridors of Ukraine
    (Publishing House of University of Technology, Katowice, 2022) Muzykin, Mykhailo I.; Nesterenko, Halyna I.; Kuzmenko, Albina
    ENG: The increasing role of education and science in modern society has caused changes in its understanding. Modern education becomes a condition for the country's development, a guarantor of its security, determines the level of the economy. Thus, education and science for sustainable development must function as a direct generator of new socio-economic life and produce social, environmental, and economic changes towards sustainable development. In addition, one of the main tools for sustainable development should be the close interaction of education with science. Therefore, the problem of supporting the development of education and science is deeply social and is one of the priorities of social development, which is directly related to the system of national interests, improving the quality of life and national security. The monographic research presents the scientific works of the team of authors that reveal different directions and aspects of science and education in providing sustainable development. These are: 1) Financial and Economic Principles of Sustainable Development; 2) Innovative and Information Technologies in Education: Applied Aspects; 3) Socio-Humanitarian Aspects of Sustainable Development; 4) Technical Solutions to Ensure Sustainable Development. The third section of the monograph "Socio-Humanitarian Aspects of Sustainable Development" looks at the environmental, linguistic, psychological, cultural, and art-therapeutic aspects of the development of society. The team of authors hopes that the monograph contains useful research results that are relevant for scientists, students and anyone interested in various aspects of education and science, given their significance in various areas of public life.

    Formulation of the Mathematical Model for the Planning System in the Carriage of Dangerous Goods by Rail
    (IOP Publishing, 2020) Bibik, Svitlana I.; Strelko, Oleh; Nesterenko, Halyna I.; Muzykin, Mykhailo I.; Kuzmenko, Albina
    ENG: The paper aims to the topical issue of improving the system in the planning of carriage of dangerous goods by rail subject to ensuring a high level of safety of the transport process and minimal costs for its implementation. Formalization of this process leads to the formation of an optimization task of the two-stage mathematical model. To implement the first stage, a mathematical model in searching the best route based on risk minimization is developed. In order to exclude the unacceptably complex and expensive options for the carriage of dangerous goods from the many possible routes, the authors abided by the condition not to exceed the critical operating costs. The second stage in the process of planning routes for dangerous goods takes into account the hazard identification study in the technological process of car movement with dangerous goods. Considering that the probability of a potential traffic accident is a complex random variable, which is due to a set of elementary previously unknown events, its estimation was made on the basis of the Bayesian approach. Based on the simulation results, the following reliability values are determined at which a transport accident should not emerge.

    Improvement of the Automated Control Technology of Trains Traffic with Dangerous Goods
    (IEEE, 2021) Bibik, Svitlana I.; Nesterenko, Halyna I.; Muzykin, Mykhailo I.; Kuzmenko, Albina
    ENG: This article is devoted to the actual issue of improving the automated control technology of trains traffic with dangerous goods due to the addition of the existing set of tasks. These tasks are solved on the basis of operating automatized working places of dispatching personnel, by the software for decision-making support system developed on the basis of the graph of the Bayesian Belief Network that describes the security status of trains traffic en route. The scientific value of the article lies in the development of new technology for planning and managing the transport of dangerous goods through intelligent support for decisions at the tactical and operational levels.
