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.

Today, one of the main important tasks is to analyze the states of achievement related to the required levels for marine passenger terminals and their route networks, depending on the influence of the external environment (based on the discretization of processes). This proposal is relevant both to increase the passenger traffic and to change the route network of ferry lines. There is an uneven congestion of individual directions of ferry lines and passenger terminals, which determines the need to select a finite number of states for the efficient operation of the «passenger terminal-ferry line» system. For the research of changes and assessments, it is proposed to use the process discretization methodology and the formation of a new circos plot intensity diagram. This study focuses on the passenger terminals in the Adriatic Sea and the existing route network in this region. As a result of the analysis, a set of points in time are selected that are characterized by various intensities and passenger traffic. For the selected set of values, a set of new intensity circos plot diagrams are constructed. On their basis, it is possible to analyze the mutual influence of the passenger terminals on each other to analyze the ferry transportation market and the number of shipping companies on it. New scientific approach can improve the quality of research and decision-making process for research of the «passenger terminal-ferry line» system. The practical results we can see in the form of circos plot diagrams for sea passenger transportation in the Adriatic Sea region and the proposed research methodology for research and operation analysis of the «ferry line-marine passenger terminal» system based on process discretization.
