The travel industry is a complex system with diverse economic links. It brings together a large number of industries whose function is to meet the growing demand for tourism products and services. Moreover, world trends in tourism development indicate that its role is growing both locally and globally. To confirm, if we look at individual indicators using the analytical method, according to the International Tourism Organization, the share of tourism in world GDP is about 9% and about 30% in world exports of services and 6% of world trade. The tourism industry employs more than 235 million people or every 12-th worker. If in 2015 about 983 million foreign tourists used the services of the tourist industry, in 2017 their number reached 1 billion. World Tourism Turnover by the end of 2018 reached over $ 1.2 trillion. USA (https://ec.europa.eu/eurostat/). It is estimated that Western Europe and the United States receive the highest profits from tourism. Taking a closer look at the characteristics of these indicators, it should be noted that during the period 2014-2018, the share of direct revenues from tourism activity in the structure of GDP production increased slightly from 1.42% to 1.44% respectively over the years. At the same time, in recent years, the total contribution of tourism to the GDP of the country has significantly increased, more than twice or by 97.6 billion, indicating that the tourism industry is gaining importance for the development of the economy and social sphere of Ukraine. By region, the largest number of tourism enterprises is located in Kyiv, Odesa, Lviv and Dnipropetrovsk regions; the smallest number is in Luhansk, Kherson and Zhytomyr regions (Ukraine). Most European countries have a good tourist image, a long tradition of quality tourism services, making extensive use of marketing tools to promote tourism services. Being located in the center of Europe and possessing the potential of tourist attraction, Ukraine has every opportunity to become its tourist center. However, in the current context, our country holds a small share of the world and European inbound tourism market, mainly serving as a tourist supplier to these markets, which means an outflow of funds from the country. Among the problems of development of the sphere of tourist services are following: 1) the political situation in the country; 2) poor information promotion; 3) inconsistency of the quality characteristics of the provision of tourist services; 4) inconsistency of legal regulation; 5) lack of a consistent state policy in the field of tourism; 6) poor quality of transport in the country; 7) domestic tourism. To continue the transformation, the Tourism and Resort Development Strategy for the period up to 2026 was approved. In the long term, the economic effect of the strategic goals of tourism market development will be reflected in the increase of tax revenues from all levels of tourism activity, increase of tourist flows, especially of foreign citizens, attraction of foreign investments in development of tourism infrastructure, creation of new jobs, increase in the volume of tourist services provided. As a consequence, creating systemic and complex transformations in the tourist services market will help accelerate the country's economic growth.

Effective application of slag-forming mixtures (SFM), being fed into continuous castingg machine (CCM) moulds, depends on their even distribution on the melt surface. Manual feeding of the SFM which is widely usedd does not provide this condition, resulting in the necessity to actualize the work to elaborate systems of SFM mechanized feedingg into moulds of various types CCM. A concept of the designing of a system of SFM feeding into CCM moulds presented with the ratte strictly correspondent to the casting speed and providing formation of an even layer of fine material of given thickness on the whoole surface of liquid steel. The proposed methods of designing of the SFM mechanized feeding systems based on three-dimensional computer simulation with the subsequent verification of the correctness of the adopted technical solutions on field samples. Informattion is presented on the design features of the adjusted facilities intended for continuous supply of finely granulated and powder mixtuures on metal mirror in moulds at the production of high-quality billets, blooms and slabs. Variants of mechanical and pneumo-mechaanical SFM supply elaborated. At the mechanical supply the fine material from the feeding hopper is moved at a adjusted distance bby a rigid horizontally located screw. At the pneumo-mechanical supply the metered doze of the granular mixture is delivered by a sshort vertical screw, the lower part of which is located in the mixing chamber attached from below to the hopper and equipped with ann ejector serving for pneumatic supply of the SFM in a stream of transporting gas. It was proposed to use flexible spiral screws in the ffuture facilities of mechanical SFM feeding. It will enable to eliminate the restrictions stipulated by the lack of free surface for locatiion of the facility in the working zone of the tundish, as well as to decrease significantly the mass of its movable part and to decreaase the necessary power of the carriage moving mechanism driver. The novelty of the proposed technical solutions is protected by thhree patents. The reduction of 10–15% in the consumption of slag-forming mixtures during the transition from manual to mechanizeed feeding confirmed. The resulting economic effect from the implementation of technical development enables to recoup the costs inncurred within 8–10 months.

The paper gives the analysis of the problem of the primary current frequency regulation in the power system, as well as the basic requirements for NPP power units under the conditions of involvement in the primary regulation. According to these requirements, the operation of NPPs is associated with unloading and a corresponding decrease in efficiency. In this regard, the combination of nuclear power plants with a hydrogen complex is shown to eliminate the inefficient discharge mode which allows the steam turbine equipment and equipment of the reactor facility to operate in the basic mode at the nominal power level. In addition, conditions are created for the generation and accumulation of hydrogen and oxygen during the day, as well as additionally during the nighttime failure of the electrical load which allows them to be used to generate peak power.  The purpose of the article is to assess the systemic economic effect as a result of the participation of nuclear power plants in combination with the hydrogen complex in the primary control of the current frequency in the power sys-tem, taking into account the resource costs of the main equipment. In this regard, the paper gives the justification of cyclic loading of the main equipment of the hydrogen complex: metal storage tanks of hydrogen and oxygen, compressor units, hydrogen-oxygen combustion chamber of vapor-hydrogen overheating of the working fluid in the steam turbine cycle of a nuclear power plant. The methodological foundations for evaluating the working life of equipment under cyclic loading with the participation in the primary frequency control by the criterion of the growth rate of a fatigue crack are described. For the equipment of the hydrogen complex, the highest intensity of loading is shown to occur in the hydrogen-oxygen combustion chamber due to high thermal stresses.  The system economic effect is estimated and the effect of wear of the main equipment under cyclic loading is shown. Under the conditions of combining NPP power units with a hydrogen complex, the efficiency of primary reg-ulation is shown to depend significantly on: the cost of equipment subjected to cyclic loading; frequency and intensity of cyclic loading; the ratio of the tariff for peak electricity, and the cost of electricity of nuclear power plants.  Based on the developed methodology for assessing the effectiveness of the participation of nuclear power plants with a hydrogen complex in the primary frequency control, taking into account the damage to the equipment, the use of the hydrogen complex is shown to provide a tangible economic effect compared with the option of unloading nuclear power plants with direct participation in frequency control.
