Combined cargo transportation in Ukraine is characterized by the presence of uncertain risks. The aim of the article was to propose a mathematical model for choosing the mode of transportation that would correspond to the best value of the integral objective function in the presence of fuzzy, stochastic and uncertain risk parameters. The efficiency of the mathematical model provided the possibility of forming not only long-term forecasts that require significant time, but also short-term forecasts in real time. This allows to quickly change routes and conditions of transportation. Practical testing of the mathematical model revealed the assimilating nature of some uncertain risks. The results of the analysis are given in the article. The realization of such a risk leads to a radical change in all conditions of transportation. Long-term forecasts allow to predict new routes and conditions of transportation.

Research shows that the risks of multimodal transportation in the Northern ports of the Azov and Black seas, in real time, can vary by large quantities. This can cause significant problems for dynamic management of transportation, providing that transportation costs and time are minimized. Therefore, it is essential to formulate a mathematical model to determine the integral risk of freight traffic involved as it could help minimize the need for additional computer resources for the operation of logistics machinery. Determining the value of the integral risk is further complicated by the fact that the mathematical apparatus used for calculating stochastic and fuzzy risks tend to differ from one another. Therefore, an additional tool developed for the unification of various mathematical apparatus was done. The main task was conversion of local risks weight factors to components of integral risks, determined in actual time. The mathematical model has been tested for the dynamic management of freight traffic on the Black Sea ports - Mariupol, Odesa, Chornomorsk, Mikolaev, and Kherson. The route optimization was carried out for container and bulk cargoes, in particular, for grain cargoes. This allowed coverage for the whole range of risks that are inherent to multimodal transportation within the Azov-Black Sea region. The results confirmed that such an approach grants the possibility to choose routes with minimal transportation costs and time, as well as minimization of the use of computer resources.

Topicality. Technological innovations of the fourth industrial revolution have had a significant impact on the development of logistics and the organization of logistics and transportation throughout the world. These processes were also facilitated by the globalization of international trade, the transnationalization of large companies, and the growth of volumes of commodities’ production, which involves the unrestricted movement of resources and goods between countries and continents, which can only be realized under the presence of a strong and developed transport and logistics infrastructure. The growing role of transport and logistics services is confirmed by the UNCTAD data, according to which 63 % of the World's volume of investment stock belongs to the services sector, 23.4 % of which - to the transport and logistics services.The geo-strategic position of Ukraine allows it being a convenient place for transit transportation of cargoes and passengers between the countries of Europe, Asia and the Middle East. Four Crete transport corridors pass through Ukraine. The transit transposition of Ukraine is an absolute advantage of the country, which makes national market attractive for foreign investors and producers.World trends show, that recently in the sphere of transport logistics, new cargo delivery technologies and innovative approaches to transport infrastructure have emerged. That is why the relevance of the choice of the paper topic is related to the study of the impact of innovative technologies of the fourth industrial revolution on the development of transport logistics. There is a large number of ambitious projects that will be analyzed in this study. This will allow us formulating suggestions on the implementation of the most promising projects of transport logistics to implement them in Ukraine. They will be aimed at increasing the competitiveness of both logistics enterprises and the country as a whole.Aim and tasks. The purpose of the article is to study the impact of innovative technologies on the development of transport logistics in Ukraine and to formulate suggestions on the implementation of the most promising projects into the transport and logistics infrastructure of Ukraine. Research results. The article reveals the main meta-trends in the development of logistics for the nearest future, namely: 3D printing, IoT, UAV, autonomous transport and underground cargo delivery. The analysis of the logistics market showed, that in Ukraine over the past 10 years the development of logistics has showed a predominantly negative dynamics : almost no water transport (only 1 % of total freight turnover); due to the state of roads and restrictions on the traffic of large-sized transport, only recently road haulage has begun to show a positive dynamics, while rail transport is still the main type of cargo transportation in Ukraine. The project of a logistics infrastructure for underground cargo delivery for the Odessa region and Ukraine as a whole is suggested. Within the framework of this project, a possibility, the potential cost and the profit from the implementation of the underground cargo network in Ukraine have been analyzed. According to the analysis, at the expense of the profit from this project, the payback period will be 7 years, and only one year after the project implementation the profit is expected to increase by 51 %. Conclusion. Ukraine has an extremely favorable geopolitical location; several international transport corridors pass through the country, but at the moment the degree of the use of transport infrastructure in Ukraine is rather low. In recent years, the country has been active in supporting initiatives related to the development of international transport corridors, defining their creation and development as a priority direction in the development of the transport complex of Ukraine. According to the analysis, the attraction of investments for the introduction of modern transportation technologies will lead to a significant increase in the profit from freight transportation and will allow Ukraine to take the leading position in the market of logistics services in Europe.

Introduction. The effective development of the internal market for agricultural products is hampered by the viola-tion of the income distribution proportionality between the subjects of its production and the circulation. This is due to the influence of many factors, so it is necessary to find ways to increase the adaptability level of marketing and logistics systems of agricultural business entities. The purpose of scientific research is to develop theoretical and practical aspects of adaptability of marketing and lo-gistics systems of agricultural business entities. Results. The formalization necessity of the quantitative estimation method of the realization nature of economic in-terests of subjects was established in production spheres and the circulation of internal agricultural production. No competi-tive situation has been identified at different levels of the marketing infrastructure of the given market. The formula is pro-posed for calculating the indicator, which characterizes the subjects’ dominance of circulation, and calculates its value for the markets of wheat grains of the third class, marketable sunflower, pork, poultry in all categories, milk. The interpretation of the analysis results is given. The possibility of using the methodology to determine the dominance level of a certain group of subjects in the agrarian market, influencing the behavior of other participants of market processes is substantiated. It is suggested to use this technique to analyze the realization completeness of entities economic interests serving the sales chan-nels. The object markets were ranked according to the increase in the production profitability and the products sales by the manufacturers. The process of the object market development is characterized. The interpretation in the indicator values change is given from the point of view of economic processes in the agricultural market. The laws of formation and function-ing of the strategic management system of marketing and logistic activity have been determined. Comparison of the classes and types of marketing and logistic strategies of agricultural enterprises is presented. The principles of the construction and orientation of the strategic management system of marketing and logistic activity are outlined. Conclusions. It is necessary to maintain an adequate level of adaptability in order to ensure the proper functioning of marketing and logistics systems of agricultural business entities. This property depends on the financial condition, activity parameters, economic potential and other characteristics of the agricultural enterprise. Adaptability of marketing and logistics systems contributes to the profitability increase of agricultural enterprises in the sphere of production and circulation. Keywords: logistics, logistic activity, logistics system, marketing, marketing of agricultural products, agrarian enterprise, sales channel, marketing communications.
