“…For an example of practical use of the proposed mathematical model (a block diagram of the mathematical model is shown in Figure 1), we do not give its application in real time for the transportation of commercial goods, as it is associated with both trade secrets and is a narrow utilitarian application, which is uninteresting to the general public, but analyze and forecast redistribution of load for a longer time interval for transport hubs-seaports of Ukraine as transit points of multimodal transportations. To do this, we use the results of calculations given in [27,36] as reference values of risks. As reference data for calculations, we also use the above-mentioned sources of official statistics: the State Statistics Service of Ukraine [30] and the Association of Seaports of Ukraine [31].…”

This article considers the use of the entropy method in the optimization and forecasting of multimodal transport under conditions of risks that can be determined simultaneously by deterministic, stochastic and fuzzy quantities. This will allow to change the route of transportation in real time in an optimal way with an unacceptable increase in the risk at one of its next stages and predict the redistribution of the load of transport nodes. The aim of this study is to develop a mathematical model for the optimal choice of an alternative route, the best for one or more objective functions in real time. In addition, it is proposed to use this mathematical model to estimate the dynamic change in turnover through intermediate transport nodes, forecasting their loading over time under different conditions that also include long-term risks which are significant in magnitude. To substantiate the feasibility of the proposed mathematical model, the analysis and forecast of cargo turnover through the seaports of Ukraine are presented, taking into account and analysing the existing risks.

Modern trends of trade-economic relations of the countries within the COVID-19 pandemic have been systemized in the development of mutual relations in particular economy sectors have been identified. Direct connection between the increase of export volume to China and Ukraine GDP growth has been established in the study based on the correlation-regression analysis. Weaknesses and strengths as well as opportunities and threats of mutual relations within the pandemic have been defined. The influence of the world crisis, creating a free trade area, and other factors on foreign trade circulation between Ukraine and China have been studied with the tools of empirical gravity model of international trade. Foreign trade circulation up until 2022 with and without creating a Free Trade Area has been forecast based on the modelled data. Perspective directions of trade-economic relations have been defined; the strategy of extending the trade-economic integration of Ukraine and China within the COVID-19 pandemic and in post-pandemic time within customs tariffs liberalization, intensification of symmetric interdependence and complementarity between the countries, within creating a free trade area, diversifying trade turnovers, overcoming the pandemic, reduction of crisis consequences, and strengthening cooperation in new industries of post-pandemic time has been grounded.

“…According to the authors' study, the level of risks listed in [19] is currently lower by 21−27 %, but the tariff policy of Black Sea ports of other countries will impose restrictions not taken into account in [19,20] on the volume of transit and container traffic through Ukrainian ports. It is established that the projected in crease in the volume of container traffic on the world market will not lead to an increase in the rate of traffic (the trend line is 100 000 000 110 000 000 120 000 000 130 000 000 140 000 000 150 000 000 160 000 000 170 000 000 180 000 000 Fig.…”

Purpose. To develop a model of minimizing transportation risks for strengthening the criteria for sustainable and safe positioning of the fleet. Methodology. Scientific research, whose results are given in the presented article, is performed using both general and special methods of cognition. Methods of quantitative and qualitative comparison, content analysis, scientific abstraction and systematization and the method of mathematical formalization were used. Findings. An algorithm of a criterion-based approach to sustainable and safe positioning of the fleet in the presence of international transport market constraints is proposed. A mathematical model has been developed for minimizing transportation risks, which will reduce the current costs of the merchant fleet and, accordingly, contribute to its sustainable and safe positioning. Since it is important for industrial enterprises to reduce the time and cost of delivering raw materials, components, reducing transport costs for delivering products to the consumer, the paper presents forecasting of volumes of container transportations through ports of Ukraine and comparative analysis with the forecast trend of container transportations in the world market. This made it possible to form a tool for determining the appropriate positioning of the fleet. Originality. The study developed an algorithm for a criteria-based approach to sustainable and safe fleet positioning under international transport market constraints and a mathematical model to minimize transportation risks. This allows moving over to the formation of an integrated multimodal transport system and coordinated actions of all market participants in transport services. The efficiency and reliability of the system will be enhanced by the ability to predict the reorientation of routes associated with increased risk and dynamic management of traffic flows. Practical value. The results of the study can be used to create integrated automated information systems for dynamic traffic management using alternative routing of traffic flows to minimize risks. The results of the forecast study on container traffic through Ukrainian seaports can be used for practical or scientific purposes.
