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.

“…The presented mathematical model (1−4) allows, taking into account the risks, to predict the integrated volume of traffic through Ukrainian ports [19]. Since "the need for innovation to maintain the position of the merchant fleet is corrected by the need to expand intermodal transport technologies" [12] and that, even in terms of regional freight transport, positioning maritime transport systems in the market by external constraints requires adjustment of intermodal transport corridors [12], to confirm the practical significance of the study using statistical data on the vol ume of container traffic on the world market (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.

“…Referring to the foregoing discussion and due to the desire to achieve a deep understanding of the feasibility assessment as to the communication and informatization service enterprises' integration and interoperability, our research puts forward the following hypothesis: the creation of integrated enterprises can provide employment opportunities based on their own re forms, reduce costs and increase efficiency through synergy and harmonization of approaches in logistics [15,16], engi neering [17], information technology [18], quality manage ment fields [19], etc.…”

Purpose. Development and scientific substantiation of the methodological approach and the expediency of communications and informatization service enterprises integration and compatibility at association, thus elaborating practical recommendations for that methodological approach application. Methodology. A combination of integral assessment methods, computational and constructive method, structural-logical and qualitative system analysis and synthesis methods was used in this study. Findings. As a result of introducing the methodological approach, the calculation is suggested of communications and informatization service enterprises adaptivity indicators to interoperate with other enterprises within the integrated system frame, which indicate the need for the chosen enterprises integration. These indicators reflect the presence of their reciprocal production, technological and personnel links, i.e. the enterprises tendency to integrate. The choice of expectedly integrable enterprises cannot be random. Therefore, to justify economic feasibility of the integration it is necessary to calculate the compatibility indicators. Originality. The proposed scientific and methodological approach gives the possibility of identifying the most favorable preconditions for the establishment of communications and informatization enterprises integrated activity form in a particular economic region. In contrast to the existing ones, this approach involves the following stages: 1.Assessment of influence rendered by the communications and informatization enterprises integration form of activity factors taking into account the development peculiarities of that economic region where the integration system is located. 2. Analysis of financial condition of communications and informatization enterprises integrated to the system. 3. Evaluation of efficiency of resource use at the integrated systems communications and informatization enterprises in order to identify savings or excessive spending as to the particular type of resources. 4. Analysis of communications and informatization enterprises compatibility with other enterprises making part to the integrated system. Practical value. The study results can be used by scientists and practitioners in the field of communications and information service enterprise management to determine the feasibility and effectiveness of these enterprises integration, depending on the motives and goals of integration, as well as to determine the compatibility potential of enterprises making part to the integration structures.
