WAYS OF ENSURING THE COMPETITIVENESS OF SMALL AND MEDIUM-SIZED MACHINE-BUILDING ENTERPRISES OF UKRAINE IN THE EUROPEAN INTEGRATION CONTEXT

The issues of the modern direction of sustainable development of the competitive machine-building industry in Europe and the possibility of transforming the experience of developed European countries into a strategy for the development of small and medium-sized machine-building enterprises in Ukraine are considered. It was noted that it is SMEs that are the basis for the development of the EU economy, and the rationale for this fact was given. It was emphasized that the engineering industry is the largest sector of the EU economy in terms of the number of enterprises, employment of workers, production and value added. It is assumed that it is the development of SMEs in the machine-building industry of Ukraine that will become a significant contribution to the accelerated restoration of the social and economic well-being of Ukrainian society during the period of the country's recovery. A comparative analysis of the numerical number of machine-building enterprises of various sizes is given both in the developed countries of Europe and in Ukraine. The need for the development and implementation of digital services in the machine-building industry of Ukraine, in accordance with the concept of Industry 4.0, was emphasized at all stages of the product life cycle to ensure the flexibility and competitiveness of SMEs. The barriers to the implementation of the 4.0 concept for the sustainable development of small and medium-sized businesses in the world are analyzed, and individual barriers are identified that today pose a threat to the development of the Ministry of Railways of Ukraine as a whole. It is noted that one of the biggest problems in the world development of the Ministry of Railways as a whole is the problem of training (retraining) a new generation of qualified personnel. It is concluded that in order to develop competitive SMEs in Ukraine in the context of its integration into the EU, it is necessary to pay attention to the training of highly qualified technical personnel who, on the one hand, can play the role of system integrators and implementers of Industry 4.0 tasks, and, on the other hand, be able to solve the associated problems of mechanical engineering technology from idea to product manufacturing using digital services based on a single digital core. The scientific value of the work lies in the substantiation of ways to ensure the competitiveness of SMEs based on the foundations of the symbiosis of education, science and manufacture on the basis of a single digital core.

ОПТИМІЗАЦІЙНЕ МОДЕЛЮВАННЯ ПІДВИЩЕННЯ ФІНАНСОВОЇ БЕЗПЕКИ МАШИНОБУДІВНИХ ПІДПРИЄМСТВ

At machine-building enterprises of Ukraine, due to the use of outdated equipment and equipment, lack of long-term sources of financing of current assets, low level of innovation activity and investment attractiveness; low product competitiveness; insufficient number of highly skilled personnel, there is a decrease in financial security and slowing down of reproductive processes. The methodological approach to improving financial security, taking into account the acceleration of reproductive processes of machine-building enterprises based on multicriterial vector optimization, allows us to determine the optimal values manifestations of dynamics of working capital and net profit, taking into account the acceleration of reproductive processes of machine-building enterprises as well as establish the optimal relationship between them. The approbation of a methodological approach to improving financial security and accelerating reproductive processes on the example of four machine-building enterprises of Ukraine. To build optimization vectors uses financial statements for eight periods. To increase the financial security and acceleration of reproductive processes of machine-building enterprises of Ukraine, certain volumes of current assets are established, the periods of their circulation, their marginal cost, taking into account various sources of funding, as well as maximum net profit in certain manifestations of dynamics of working capital. In the process of implementing a methodological approach to improving financial security and accelerating reproductive processes into practical activities of machine-building enterprises, a significant role and place occupy highly skilled personnel. The decisive tool for their provision is: material stimulation (salaries increase, provision of premiums) and establishing mutual in the team (social justice in the department). Therefore, the further direction of research is to develop a methodological approach to improving the financial security of machine-building enterprises, taking into account staffing.

Дослідження сучасного стану та тенденцій розвитку логістичної діяльності машинобудівних підприємств

The current state and trends in developing logistics activities at machine-building enterprises is studied through evaluating the efficiency of financial flows. It is noted that studying the current state and trends in the logistics activities at machine-building enterprises is a necessary condition for the revival of mechanic engineering in our country. It is noted that the machine-building industry has specific features in management, which are associated with high costs for raw materials, energy, transportation, and labor resources. Mostly, products of machine-building enterprises have a fairly long usage (consumption) cycle, and are quite large, so their sale causes problems during periods of economic crisis, in contrast to, for example, food products. It is established that for the industry to undergo sustainable development, it needs to attract capital investments. The general problem with the level of financing, including the machine-building industry, negatively affects the prospects for reorganizing the production cycle, involving innovative technologies, introducing resource- and energy-saving processes in production, complying with environmental management. It is this set of conditions that is the key to making products of Ukraine’s machine-building industry attractive for global market consumers, and therefore, to increasing financial flows. As a result of the study, a methodological approach to evaluating the logistics activities at machine-building enterprises by selected indices of financial logistics is suggested, where the indices can be calculated on the basis of the annual financial statements of enterprises as for their balance (statement of financial position) and financial results (statement of comprehensive income), making it possible to identify both factors influencing the results of the economic activity of machine-building enterprises, and the degree of this influence. The calculated values of the relative efficiency ratios of financial logistics in managing accounts receivable and payable related to product flows can serve as input data to build a mathematical model for forecasting the efficiency of logistics activities at machine-building enterprises in Ukraine

КОНКУРЕНТОСПРОМОЖНІСТЬ ВІТЧИЗНЯНОЇ ПРОДУКЦІЇ НА МІЖНАРОДНОМУ РИНКУ МАШИНОБУДУВАННЯ: РЕАЛІЇ ТА ПЕРСПЕКТИВИ

The essence of the concept of "product competitiveness" is considered. The factors of competitiveness of products of machine-building enterprises on the international market are systematized. Based on the systematization of quantitative and qualitative methods of assessing the level of competitiveness, a step-by-step method for mechanical engineering enterprises is proposed. The state of the machine-building complex of Ukraine is considered. The dynamics of factors of international competitiveness of machine-building enterprises is analyzed: number of enterprises by machine-building branches; volume of sales and production of machine-building products; shares of mechanical engineering products in domestic exports; capital investments of enterprises in the fields of mechanical engineering. As a result of diagnosing the factors, a PEST-analysis of the domestic machine-building complex with the division of factors into political, economic, social and technological was carried out. It is established that machine-building enterprises of Ukraine have a low level of competitiveness in international markets due to a number of negative factors, the key of which are: insufficient demand in foreign markets, high dependence on fluctuations in resource prices (economic); imperfect legislation, the war in eastern Ukraine (political); technological and moral obsolescence of products and fixed assets, high energy consumption and low productivity, low costs of R&D (technological); lack or outflow of qualified manufacturers abroad, low wages, low motivation of job seekers to employment in the field of mechanical engineering (social). Measures to increase international competitiveness which are proposed include following: preferential lending; revival of basic and applied science; reforming the legal regulation of intellectual property; ensuring compliance of products with European technical regulations. Prospects for the development of domestic engineering: digitalization, development of robotics, technology of Industry 4.0, infrastructure of technology parks.

The place and role of corporations in domestic machine building

The main trends in the development of machine-building enterprises in Ukraine are studied. The research proves that large and medium-sized machine-building enterprises sell more products, and the level of profitability of their activities is higher than that of small enterprises. These trends are due, in particular, to the fact that large and medium-sized machine-building enterprises could provide greater funding for the production and development of technical and technological processes, the creation of research units and diversification of markets through international trade and more. A decrease in investment in the development of domestic machine-building industries and a decrease in the share of machine building in investment financing of the industrial sector of the economy are revealed. The paper specifies that in recent years, international corporations, which have established their subsidiaries and production units in Ukraine, have started to play a significant role in the structure of machine-building industries. The share of TNCs in machine-building industries is determined. In particular, the paper shows that in 2020, about 18 subsidiaries of well-known world manufacturers of machine-building products were active, producing 10.45% of sold machine-building products in Ukraine. Such companies involved 10.32% of mechanical engineering workers in general, and the wage bill was 12.45%. The production specialization of machine-building TNCs is outlined. These are mostly intermediate manufacturers engaged in the manufacture of individual components for leading automotive companies. The research emphasizes that the vast majority of machine-building TNCs in Ukraine operate on tolling schemes. Foreign companies are the consumers of TNCs' final products. Accordingly, the share of such products in the Ukrainian export of mechanical engineering is also quite high. This primarily applies to the production of electrical machines (subgroup 85). The expediency of the development of domestic industries to strengthen their competitive position in domestic and foreign markets is emphasized.

Прогнозування запасів промислового підприємства в умовах волатильності попиту

The aim of the article is to provide tools for obtaining reliable forecasts of the level of inventories of the enterprise in conditions of volatility in demand for products. Most types of demand for industrial products are unstable, so it is important to form stocks based on demand forecasts to reduce logistics risks. The results of the analyses. Analytical tools for forecasting maximum level of inventories in conditions of volatility of demand for products of machine-building enterprises have been developed, which provides an opportunity to obtain the most reliable sales forecast and estimate the maximum required stocks for a certain type of demand. The method, which is obtained by analytical tools, is based on a three-stage algorithm: a) identification of trends in a time series of sales; b) obtaining optimal sales forecasting models; c) plotting of interval forecasts of product sales and risk assessment of the formation of its maximum stocks. The developed methodology identifies logistics risks, which depend on sales forecasts, for nine machine-building enterprises of Ukraine. A method for statistical assessment of logistics risks of machine-building enterprises by confidence intervals has been developed, in which maximum stocks are determined by two confidence intervals of sales forecasts, and the risk of error is associated with the appropriate levels of reliability of these intervals. It is proposed to build the upper limits of two confidence intervals, for example, 95% and 99%, according to the forecast inventory level estimates, and to consider them as maximum inventory level estimates with corresponding probabilities. The risk of stock shortages is defined as the probability of going beyond the upper limit of the corresponding interval. It is proved that the dynamics of monthly or quarterly sales of enterprises can be typed by four patterns: the presence of seasonal fluctuations and trends; the presence of purely seasonal fluctuations without a pronounced trend; no seasonal fluctuations, but the presence of a trend; no seasonal fluctuations and trends. Conclusions and perspectives for further research. It is proved that the volatility of monthly or quarterly sales volumes of enterprises can be typed by four patterns: 1) the presence of seasonal fluctuations and trends; 2) the presence of purely seasonal fluctuations without a pronounced trend; 3) no seasonal fluctuations, but the presence of a trend; 4) no seasonal fluctuations and trends. Based on this, the theoretical and methodological principles and analytical tools for forecasting the maximum stocks of an industrial enterprise in conditions of demand volatility were improved. Keywords: seasonality, volatility, inventory level forecasting, maximum stocks, demand forecasting.

ВПЛИВ ТЕМПЕРАТУРИ ТЕРМІЧНОЇ ОБРОБКИ НА СТІЙКІСТЬ ДО МІЖКРИСТАЛІТНОЇ КОРОЗІЇ ЗВАРНИХ З'ЄДНАНЬ

Welded joints with corrosion-resistant steels and heat-resistant alloys requiring different modes of heat treatment to achieve the level of mechanical properties specified in the design documentation are used to manufacture parts and components of the rocket engine turbo-pump unit.For the manufacture of parts and assemblies of liquid-propellant rocket engines at the machine-building enterprises of Ukraine there was a necessity of replacement of half-finished products because of certain difficulties at delivery of materials from EU countries.First of all, it was necessary to replace flat products from high-alloy ХН67МВТЮ and 06Х15Н6МВФБ with one alloy that would possess the necessary set of physicomechanical characteristics. In the work, as a replacement for the used heat-resistant alloys, the Inconel 718 alloy welded to 316L steel was chosen. As a result of comparative studies of the intercrystalline corrosion resistance of welded joints of the heat-resistant Inconel 718 alloy with stainless steel, after testing various heat treatment conditions, the low-temperature heating conditions were recommended for soldering at a temperature of 950°C. Samples of welded joints, processed according to the recommended mode, showed increased corrosion resistance.

ВИВЧЕННЯ УМОВ ПЕРЕМІШУВАННЯ ТА ТЕПЛОВОГО СТАНУ РОЗПЛАВУ ПРИ ДЕГАЗАЦІЇ СТАЛІ НА ОБЛАДНАННІ КАМЕРНОГО (VD) ТИПУ

Increasing requirements for the quality of metal products are regulated by international, state standards and other documents, in particular, on the content of gases and non-metallic inclusions in metal. In some cases, normative documents stipulate the need for degassing of steel with high quality requirements, including flock-sensitive grades. For this purpose, equipment for chamber (VD, VOD-types) degassing is used at metallurgical and machine-building enterprises of Ukraine. Due to insufficient knowledge of the process of degassing, real numerical studies have been carried out. As the object of study, we determined the installation for the degassing of the Mannesmann Demag company of the above type with a 60t bucket with reinforcement of the lining in impact zone of the PJSC «DSS» enterprise. Based on the initial data of the degassing process, a mathematical model was developed by DSTU to consider heat and mass transfer processes in a liquid metal bath during its degassing. Specialized software has been created that allows you to take into account the changing technological parameters during metal processing in vacuum, the configuration and capacity of the bucket bath. Employees of the ISI of NASU using the database on out-of-furnace processing of electric steel at PJSC «DSS» for the previous period determined that the values of the mass of the heats were in the range from 54t to 66t. Given the previously established that the intensity of argon purging through the bottom (s) tuyeres (s) and different masses of metal in a ladle of the same capacity from smelting to smelting create different hydrodynamic and thermal conditions for metal processing processes in the bucket, and the above information required an additional evaluation of the process degassing. At the first stage of numerical studies, the hydrodynamic conditions of degassing in a metal bath were studied taking into account the listed influence factors. Contour diagrams of the vertical component of the velocity of metal flows in different vertical axial sections of the bath were constructed at 20 minutes of degassing (at a pressure of 1 mm Hg). In the given vertical sections, the descending metal flows are concentrated in the upper half of the bath, and the ascending flows in its lower half. It was noted that with an increase in the flow rate of argon for mixing with the same mass of smelting, the absolute values of the vertical component of the metal velocity increase, and with the same consumption of argon, it decreases with an increase in the mass of smelting, which is similar to processing conditions at normal atmospheric pressure. At the second stage of research, thermal conditions were studied during the degassing of steel at a similar reduced pressure. Contour diagrams with isotherms (average metal temperature in the ladle) are constructed depending on the duration of the degassing process and argon consumption. A comparative assessment of the thermal conditions during degassing on chamber-type equipment and on LF (at normal pressure) with operating conditions at a similar initial temperature and the corresponding argon flow rate was made. An increase in heat loss by metal was found with an increase in argon consumption and with a decrease in smelting mass. Thus, it has been established that the mixing features of the metal bath create different hydrodynamic conditions for the degassing process on the chamber-type equipment, affect its thermal state, which probably can affect the efficiency of gas removal.

Features of formation of innovation-investment policy on industrial enterprises

The article deals with the peculiarities of the formation of innovation-investment policy at industrial enterprises. The paper emphasizes the fact of the lack of institutional support of innovative activity of Ukrainian’s enterprises, which is the reason why there is a lack of a national innovation priorities concept and a systematic approach to the development of innovation activity. The requests of substantiation of optimal development models are investigated; the principles, forms, methods of implementation of innovation and investment development policy are defined; the parameters, principles, scientific and methodical foundations of creation of modern innovative forms of development are outlined; providing scientific support for development programs is emphasized. The connection of the implementation of innovations in the economic practice at industrial enterprises with innovative entrepreneurship, which depends on the speed of conducting of restructuring processes on the basis of construction innovation-investment model development of the economy, was proved. The basic tasks were defined, namely, first of all, the active use of human capital, scientific and technical potential of its realization; forming a competitive environment; providing real state support; setting up an efficient financial and banking systems, an efficient stock market; a well-established investment process, which in turn requires improvement of the corporate governance system of enterprises that provides for transparency of the ownership structure, provision of shareholders with high-quality and reliable information. The destabilizing factors of realization of innovation-investment potential at industrial enterprises, in particular, machine-building enterprises of Ukraine were defined, among them: insufficient development of solvent internal market of machine-building products, lack of state and regional development program, significant dependence on market conditions on foreign markets; general deficiencies in the implementation of the state program of development of mechanical engineering, shortages of personnel required qualification (scientific, technical, engineering, labor specialties), lack of state financial support, and, in particular state protection against raider attacks. The paper emphasizes that venture capital company should play a special role in realizing an innovation model of development, which will enable the increase of the complexity of production; the use of the existing productive assets to a greater extent, the expanding of the production infrastructure; the creation of the basis for the formation and development of new organizational forms and production activity; the realization of the social orientation of the industry development. The necessity of stimulating the development of socially significant productions, which allows solving problems of socio-economic development without increasing the ecological burden on the natural system, was determined. It is essential to develop and implement relevant investment programs on the basis of well-defined volumes of investment resources; to increase investment attractiveness at the expense of streamlining the market space for commodity producers; to create guarantees of protection of capital and income of investors.

MANAGEMENT ECONOMIC SECURITY OF MACHINE-BUILDING ENTERPRISES IN UKRAINE

In particularly difficult circumstances today, domestic engineering has appeared. Today, the machine-building sector has faced a number of problems, primarily because of geopolitical changes in the external environment. In the context of the constant growth of competition in world markets, the national machine-building industry faced challenges of a strategic nature. In addition, many external and internal factors that have a negative impact on machine building and require research. The essential characteristics, factors of economic safety of the machine-building enterprise are considered. The purpose, indicators, measures to ensure the process of organization of economic security in enterprises are investigated in the modern conditions of their development. The existing concepts of development of domestic machine-building enterprises with the consideration of safety of their economic behavior are analyzed. The main function of personnel security as a component of economic safety of machine-building enterprises in general is described and grounded. Methodical approaches are proposed for removal of existing threats to economic security. The article analyzes the situation of the industry in the context of the main structural components of economic safety in order to determine the safety of the state of activity of the machine-building enterprises in Ukraine. It is substantiated that financial crisis was the most sensitive factor influencing the financial results of industrial enterprises. In order to assess the level of profitability of the enterprises of the machine-building industry, the dynamics of profitability indicators of operating activity of mechanical engineering enterprises is researched. As a result of the analysis of internal prerequisites for the formation of economic safety of the enterprises of mechanical engineering, it was established that the level of financial security of the industry is low and needs to be changed. Consequently, the development of machine-building enterprises is accompanied by the accumulation of problems that negatively affect them. Under the influence of various factors, the development of the machine-building industry is not predictable, not by plans and programs, which are formed by governments, nor taking into account the needs of industrial products and the requirements of globalization of the world economy. The situation is getting worsewith a decreases in the time spans between global crises, which adversely affects the state of the national economy of Ukraine.
