Modern transport systems are characterized by the development and implementation of intelligent transport technologies. Today, dynamic forecast models are not used in practice in the operation of a passenger terminal. Decision making is based on some regulatory values for passenger traffic, but this is not sufficient for efficient terminal management. Modern passenger terminals are characterized by dynamic process variability and consideration of diverse options, taking into account the criteria of safety, reliability analysis, and the continuous research of passenger processing. For any modern marine passenger terminal, it is necessary to use the tool to simulate passenger flows in dynamics. Only in this way it is possible to obtain the analytical information and use it for decision making when solving the problem of the amount of personnel required for passenger service, transport safety, some forecasting tasks and so on. Of particular relevance is the choice of the mathematical transport model and the practical conditions for the implementation of the model in the real terminal operation. In this article, the analysis technique of intelligent simulation-based terminal services provides a new mathematical model of passenger movement inside the terminal and presents a new software instrument. Moreover, the conditions of implementation of some transportation models during the operation of marine passenger terminal are examined. The study represents an example of analytical information used for the forecast of the terminal operations, the analysis of the workload and the efficiency of the organization of the marine terminal.
Passenger seaports are new starting-points of urban development. They form a new independent industry, become new incentives for improving urban infrastructure and increase the tourist attractiveness of the city itself and the region. In view of changes in passenger service processes, changes in route ferry and cruise networks, due to COVID-19, the heads of ports and terminals set new strategic tasks to determine the directions for infrastructure modernization and forecast development. The regions of the Adriatic and Baltic Seas were chosen as the experimental base. To find new answers, it is necessary to solve the problem of synthesizing the structure of a sea passenger port, taking into account all processes and services, the influence of the external environment, building a system of target functions and limiting conditions. Thus, the necessity of forming informed decisions on modernization based on the construction of new mathematical models is substantiated. A new function has been introduced that describes the influence of the external environment. Particular attention is given to the study of the mutual influence of the city and the sea passenger port in order to determine the need to improve transport accessibility and change the near-port transport space. The presented models of structure synthesis and target functions, models including functions of the influence of the external environment on the system “city infrastructure-sea passenger port-ferry company” allow at a qualitatively new level to solve the problem of forecasting development and form a system making decisions to improve the position of the passenger terminal in the sea region. The developed models and synthesis problem formation are applicable to sea passenger ports and terminals in other regions of the seas. The models are applicable both at the stage of creating a new marine terminal and during the study and subsequent modernization of the infrastructure. The presented new models allow the port manager to give answers to the questions of strategic development of sea passenger ports in sea regions.
We undertook the analysis of the foreign publications concerning the application of the modern radiodiagnostic methods (including MSCT- and MRI-visualization) with reference to the solution of the traditional problems facing forensic medical expertise, such as the estimation of prescription of death coming and time of infliction of injury in the dead bodies. Both advantages and disadvantages of postmortem visualization of the corpses of adult subjects are discussed taking into consideration the period of time that elapsed between the death and the onset of the study as well as the character of the injuries. It was shown that the examination of the corpses using the up-to-date methods of radiodiagnostics prior to autopsy makes it possible for morphologists, jointly with radiologists, to identify, to see in the new light, and to evaluate the number of charges in the dead body, such as the alteration of the blood cell sedimentation rate, the formation of postmortem hypostases in the internal organs, the hardening of the walls of aorta and major blood vessels, right heart dilatation, gradual smoothing of the borderline between grey and white matter of the brain. Virtual autopsy can be useful , even for the study of such long-term processes in the corpses as putrefaction, saponification, mummification, and peat tanning. Moreover, this technique may be instrumental in the elucidation of the specific features of topographic-anatomical relationships between individual 'tissues and organs, detection of the concealed lesions, and a variety of pathological changes. Postmortem visualization allows for the quantitative evaluation of the severity of these transformations and the preliminary estimation of prescription of death coming. Also, radiodiagnostic methods can be employed to reliably visualize and measure various hemorrhagic events (from the density of such ones as liquid and clotted blood) in the tissues surrounding the fractures, in body cavities, and internal organs as well as to establish the facts of inter-vital aspiration of blood, alimentary masses, liquid and solid foreign bodies penetrating into the upper sections of the respiratory and gastrointestinal tracts as the consequence f an injury. It is concluded that the postmortem visualization techniques employed to estimate prescription of death coming and time of infliction of injury as well as other complicated problems facing forensic medical expertize need the further scientifically based development.
According to statistics, the marine passenger transportation sectors (both cruise lines and ferry lines) show a significant increase of passenger traffic and the intensity of ship routes. But new features of the conditions for passenger traffic growth require the development of new methodological transport models for cruise and ferry networks and new practical forecasting methods. Changes are observed in the fleet composition, mostly in the direction of increased. New approach for forecasting has to be based on the interaction of such systems as «city-sea passenger port-cruise and ferry lines». This condition now determines new need to describe the principles and forms of organization of maritime ferry networks and changes under the influence of the external environment. The object of the research is the Baltic Sea region and the existing route networks of cruise and ferry lines. Exploring this system, the usage of new mathematical apparatus based on correspondence matrices and agent-based simulation was justified for estimating the workload on transport infrastructure around the passenger port and for the existing ferry or cruise route network. The practical results of new simulation model, on the one hand, justify the need for a comprehensive study of the conditions for the formation of ferry and cruise route networks in changing conditions. On the other hand, these new results could improve the quality of decision-making process in forecasting the route network on the basis of the research of passenger traffic between systems «city-sea terminal-cruise line or ferry line».
