Cherednichenko K. Сomprehensive safety assessment of cargo transportation in integrated transport systems

The dissertation is dedicated to solving the crucial issue of safety assessment in cargo transportation to build pre-optimally safe transportation routes in integrated systems. This issue becomes especially relevant today – during the full-scale war on the territory of Ukraine, when the effective functioning of the transport industry is critically important for supporting the economy, meeting the needs of the civilian population, and ensuring the stability of the state. The object of the dissertation research is the processes of forming safe cargo transportation in integrated transport systems. The subject of the dissertation research is the methods and models for comprehensive safety assessment in integrated transport systems for cargo transportation. The purpose of the dissertation research is to develop methods and models for comprehensive safety assessment in integrated transport systems and their further use in designing safe cargo transportation routes. The scientific novelty of the obtained results lies in a conceptually new comprehensive approach to assessing the level of safety in transport systems, which, unlike modern methods, includes the assessment of the safety of both infrastructure objects and transportation routes. In this approach, the assessment of transport infrastructure safety is carried out on two levels: external – the assessment of external environmental threats to the object, and internal – the assessment of the performance of the safety assurance system. In particular, for the first time: - a mathematical model of an intelligent classifier for assessing external threats to infrastructure facilities using fuzzy logic has been developed, allowing for the consideration of the crime environment in which it is located and the distance from the demarcation line, which is especially important today for Ukraine due to the full-scale Russian aggression; - a mathematical model of the reliability of a transport node has been developed, which determines the operability of the safety assurance system at any given time; Improved: - a mathematical model of risk, which allows for the assessment of the likelihood of emergencies occurring on cargo transportation routes in integrated transport systems; Further developed: - methods of rational choice and construction of transportation routes by including the safety factor in the multi-criteria assessment system, which will ensure the safety of cargo at every stage of transportation during the war in Ukraine; The practical significance of the obtained results lies in: - practical application of the tested model allows for a comprehensive assessment of alternative options and the development of the safest route already at the stage of designing transport-technological schemes of integrated transportation, which, in the context of the war in Ukraine, reaches a new level of relevance and is crucial for the effective functioning of the transport industry. The main scientific and practical results of the dissertation have been implemented in the educational process of the Department of Air Transportation Management of the National Aviation University. The dissertation research results were also implemented in the production activities of LLC "FTP" in the form of a developed algorithm for solving a multi-criteria task of building optimal multimodal transportation systems and in the International Airport "Odessa" in the form of a developed model for comprehensive safety assessment of airport infrastructure.
