Availability and reliability of a manufacturing system are the most common indicators in the reliability engineering area to assess the quality and on-time deliveries of the products they produce. The purpose of this paper is to analyze the availability, reliability. failure metrics such as MTBF and MTTF, and also steady-state availability of a cooking oilproduction line using a Markov approach. The product line works in three consecutive shifts 24 hours a day, for which five main subsystems are identified for the analysis. The results show that the first shift has the best performance in terms of reliability while the second shift has the worst performance. To improve the reliability of the production line, a corrective maintenance policy is used. First, the critical components of the subsystems are identified using the Pareto charts, and then, by increasing the repair rates, the availability of the production line in all three shifts is increased.

The problem of maximizing the benefit from a specified number of a particular product with respect to the behavior of customer choices is regarded as revenue management. This managerial technique was first adopted by the airline industries before being widely used by many others such as hotel industries. The scope of this research is mainly focused on hotel revenue management, regarding which a bi-objective model is proposed. The suggested method aims at increasing the revenue of hotels by assigning the same rooms to different customers. Maximization of hotel revenue is a network management problem aiming to manage several resources simultaneously. Accordingly, a model is proposed in this paper based on the customer choice behavior in which the customers are divided into two groups of business and leisure. Customers of the business group prefer products with full price, whereas products with discounts are most desirable for leisure customers. The model consists of two objectives, the first one of which maximizes the means of revenue, and the second one minimizes the dispersion of revenue. Since the problem under consideration is Non-deterministic Polynomial-time hard (NP-hard), two meta-heuristic algorithms of Non-dominated Sorting Genetic Algorithm-II (NSGA-II) and Multiple Objective Particle Swarm Optimization (MOPSO) are proposed to solve the problem. Moreover, the tuned algorithms are compared via the statistical analysis method. The results show that the NSGA-II is more efficient in comparison with MOPSO.

The article is devoted to the study of the process of development of regions as a promising area of industrial tourism. The authors researched the marketing strategies of industrial tourism, studied, proposed an algorithm for selecting a marketing strategy for the development of industrial tourism and the concept of developing a marketing strategy for the development of industrial tourism. They also proposed a scientific and methodological approach to assessing the attractiveness of investments in the region for the development of industrial tourism and tested its practical effectiveness at 10 enterprises. Developed a mechanism for implementing a marketing strategy for industrial tourism, which is the basis for establishing the structure and composition, goals, objectives, principles, functions, methods, means of implementing a marketing strategy for industrial tourism, as well as for significant activities at national, regional and local levels of promotion of industrial tourism and industrial tourism infrastructure.

Since the subprime financial crisis, international financial regulatory institutions (Basel, MIFID, Dodd-Frank), have strengthened regulatory requirements on systemically important banks. The Basel Committee on Banking Supervision, and based on the G20 recommendations, has drawn up a reform program to reconfigure the banking system, based mainly on increasing the capital requirement. The program has caused strong resistance from the banking industry leaders, saying that an excessive increase in regulatory capital will lead to an increase in the cost of financing of banks, which will have a negative impact on their profitability, and affect in fine the entire economic system. Due to the divergence of opinions regarding the impact of increasing capital requirements on the banking system, and the drastic lack of empirical literature on the Moroccan banking sector, we have decided to direct our research to fill this empirical deficiency. The main question we want to answer through our analytical approach, is how enhanced capital regulation would impact financial performance of the banking industry? Tio which extent this impact could be alleviated through risk management policies? To do so, and based on the empirical literature on this topic, we have conducted an analytical study, through Mathematical Modeling Analysis to compute the impact of the implementation of reinforced capital regulations on the profitability of banks.The goal of this article is to present the results of the impact analysis on the profitability of Moroccan banks using regression model applied to panel data, covering the 2010-2017 time period. The relevance of this study is derived from the several reforms applied to regulation of capital in the worldwide banking industry during the post-financial crisis period, including Morocco. In Morocco, Bank Al Maghrib, the regulator of banks, introduced reforms in the regulation of capital, through circular 14 / G / 2014 and circular 1 / W / 2016, modifying and strengthening the solvency ratios. This article presents the results of an impact study conducted based on the Panel's Multiple Data Regression Model and applied to 6 Moroccan banks during the post-financial crisis period, i.e., 2010-2017.

Social networks, which emerged due to the rapid development of modern telecommunications and information technologies that led to the emergence of the Internet, can be viewed as a phenomenon of the information society. In a short time, there has been both quantitative and qualitative growth of social networks, which have become a common phenomenon in our life and the dominant way of communication of social groups in the Internet space. The article tells about the history of the emergence and development of social networks, presents a classification following their primary functionality, discloses and gives characteristics to the main opportunities that they provide to the information society. The article analyzes and compiles a popularity rating (by the number of active users) of social networks in the world and Ukraine, analyzes the motives of users visiting social networks in Ukraine and examines the main age groups by the activity of using social networks, and analyzes the development and causes of failures of Ukrainian social networks.

The purpose of this study is to determine the main directions of development of digital competencies of teachers to ensure a quality educational process in the transformation of the educational environment. The relevance of this study is due to the need to determine the main directions of development of the education system for adaptation in the context of digitalization of society. It is established thatthe transformation of the educational environment requires an increase in digital literacy and digital improvement competencies of teachers in terms of digitalization of the educational process. The effectiveness of the educational process with the use of digital technologies is based on digital competencies, which are now universal and provide participants in the educational process with adaptive mechanisms to the digitalization of society. The product of this study is the optimization of the model of digital competencies of the teacher, which establishes a single structure of digital and professional competencies based on the general theory of activity: "values - purpose (subject) - actions". The novelty of the study is determined by the fact that the paper uses the approach of identifying elements of digital competencies in the integrated application of pedagogical technologies. This approach allows us to identify levels of assessment of the conditions necessary for the construction of a digital educational process of vocational education and training. The authors show thatdigital technologies play a key role in the organization of the educational process, if you use them as a tool for collaboration, inclusion and involvement in the process of all participants, the personification of learning. Research has shown that the role of digital literacy for all participants in the learning process is growing significantly. Digital literacy, as a set of competencies, becomes the basis for the full participation in the knowledge society of the teacher personally and the involvement of their students, revealing their talents. The study was conducted on the example of Ukrainian educational institutions based on the results of the organization of the educational process during the quarantine period 2020. The assessment of the organization of the distance form of the educational process using digital tools and technologies in higher education institutions. The authors show thatlevel of skills and ability to use digital technologies in the organization of the educational process among research and teaching staff is quite mediocre, as less than half of respondents used such tools on a regular / regular basis. At the same time, a fairly high level of digital literacy of both teachers and students was revealed. According to the results, it is established that the problems of digitalization of the educational environment in Ukraine are systemic. Therefore, it is necessary to continue reforms of the education system, to implement specific measures to form a digital culture and philosophy of digitalization of the educational environment. Accordingly, the basis of such transformations is digital literacy and digital competencies of all participants.

The fact of growth of inequality in distribution of income both inside the national economies and between the countries is confirmed by many empirical studies. In particular, these are annual reports of the World Bank, UNIDO and European Commission. The growth of inequality in distribution of income causes social tension inside the countries and promotes conflicts between the countries. Entrepreneurship serves as a form of softening social tension. Entrepreneurial activity ensures a significant percentage of employment and self-employment in many countries providing the income of the population at the level above the minimum consumption rate. In some cases, entrepreneurship could serve as a social lift for transition to a higher level of income distribution. The goal of this article is a statistical check of dependence between the level of income inequality and entrepreneurial activity in countries with different levels of GDP. A system approach and correlation analysis are used as the study methods. The statistical check of a correlation between the Gini index and level of entrepreneurial activity showed significant differences in the correlation degree of the said indicators for different countries and time periods. An assumption was made that there is a statistical dependence between the indicators, however, inclusion of additional parameters, among which we can find inequality of the property distribution and the level of institutional support of entrepreneurship, is required.

The relevance of the topic of the study is due to the fact that in Ukraine today, the need to form a perfect system of public finances, stabilize and overcome the uneven regional development of the national economy, which should guarantee a corresponding increase in the financial potential of the regions, is of particular importance. as a result of the analysis of the dynamics of the volumes of financial potential of the regions during the analyzed period, significant asymmetries were revealed, which is caused by the influence of factors of the external and internal environment, both positive and negative content, as well as different levels of economic development of the regions. results of the research The result of the study is a clear identification of the tendencies of economic development of the regions of Ukraine on the basis of their financial potential and the reasons for the deepening of differentiation of development, which makes it possible to develop recommendations for improving the formation of financial potential at the level of regions, aimed at increasing the volume of this potential, which will contribute to ensuring the growing dynamics of regional development.

The application of the latest digital technologies changes the ways of thinking of entrepreneurial behaviour and motivation of decision-making, principles of organization of their functioning, so the purpose of work is to form a model of achieving a balanced balance between economic efficiency and environmental and social responsibility of the digitized enterprise, determining the scientific bases for managing such processes. Methods of grouping and formalization, structural-logical and qualitative system analysis and synthesis were used in the research process. The model of achieving a balanced equilibrium is a process of harmonizing the activity of an existing (undesirable) state and achieving an equilibrium state through gradual transformations. The mechanism of control of transformation processes contains information, resource and formative levels of management. The logical-structural matrix contains the main problems and the expected results of balanced development.

The article is dedicated to the analysis of the transformation of the worker’s competencies model in the Economy 4.0 conditions, to the identification of the causes for the increase of the labor redundancy and mismatch on the labor market. The authors identified key competencies that are important for Ukrainian businesses and made a forecast of required competencies for 2030. The analysis of the compliance of training programs of educational institutions with market requirements has practical value. The authors also proposed the roadmap for coordination of the program of the human resource manager competencies development. An important result came out to be the developed matrix of the necessary level of development of staff competencies for various divisions of the company depending on the decision-making center.

In the conditions of market infrastructure for the transformation of medical services, there is an objective need to build effective insurance protection of the population against risks associated with loss of health. Using a systematic approach, the problem of combining compulsory and voluntary health insurance is investigated, a theoretical conceptualization of the concept of “financial mechanism of public health insurance” is carried out. The solution of the above problems will contribute to the development of an adequate approach to the formation and use of funds of insurance funds for the effective functioning of the health insurance system. system. Also, the development of a more rational structure of public health will meet the needs of protecting property interests related to loss / deterioration of health.

The article investigates the peculiarities of the enterprise's innovation activity and its legal regulation, conducts the evaluation of the business strategy for chemical companies according to the manufacturer’s principles of innovation management. The purpose of the paper is to evaluate the business strategy of chemical companies according to the manufacturer’s principles of innovation management. According to the evaluation results it is determined that the business strategy is unstable and needs to be improved. Also there are negative trends in the enterprise’s development and decrease in the efficiency. The complex of recommendations to improve the business strategy which forms the basis for the methodology of the selection the most objective strategic alternative in the chemical companies is proposed. To improve the strategy the authors suggested to expand enterprise’s market share and to implement intensity of product sale for different types of products; to consider the peculiarities of legal regulation for chemical industry in the field of innovative goods production; to keep the trend of production costs reduction; to seek ways to increase the profit of the enterprise by cost control and increasing sales.

Within the article, the impact of modern digitalization processes on changing household credit behavior is considered. Much attention is paid to defining the essence of digitalization and exploring the features of its impact on the financial services market. Accordingly, the content of household credit behavior and its individual models are examined. This behavior is proposed to be considered as a process of interaction between entities engaged in joint business activities with financial institutions regarding the receipt of temporary financial resources from banking and non-banking institutions with subsequent use to meet their own needs on terms of return, payment, expediency and security. Within the article, basic features that are inherent in both the classic model of obtaining credit services by clients of financial institutions and the new model of lending, which is formed today as a result of the impact of digitalization processes, are defined and systematized. Study of the results of the analysis of current trends in the development of the financial services market made it possible to identify main perspective directions for further transformation of credit household behavior, the process of lending and changing the paradigm of lending to financial institutions.

The purpose of the article is to substantiate the theoretical positions and develop practical recommendations for the development of tools for analytical assessment of the competitiveness of an enterprise, taking into account the influence of the corruption component. It has been established that the main inalienable structural components of the analytical assessment of the competitiveness of enterprises on the market are: 1) the efficiency of the enterprise (in four components: financial and economic efficiency, commercial efficiency, production-technological efficiency, social efficiency); 2) the competitiveness of the enterprise’s products (includes calculation of such indicators as an integral indicator of product quality (useful effect), price of products, integral indicator of service quality and other additional (consumer) product parameters).

The purpose of this study is theoretical and methodological substantiation, deepening of conceptual provisions and development of scientific and practical recommendations for the formation of an integrated sector of national security and defense based on the principles of national resilience. The relevance of this study is due to the need to build national resilience to address the main problems of national security of Ukraine. The main components of national security and resilience development of the country on the basis of global indices are considered, the main patterns and key problems of national security of Ukraine are highlighted. Studies have found, which is a condition for providing national security is the formation of an appropriate level of internal resilience of the state, the basis of which is economic resilience, the rule of law, modern infrastructure, education and medicine. It is established that Ukraine is characterized by a low level of management in the public administration system, a high level of corruption, low efficiency of government decisions, non-compliance with current legislation in various spheres of life. it is proved that it is necessary for the formation of an integral sector of national security and defense a balanced combination of the capabilities of the main elements of the national security system and the objects of national resilience. Priority areas for building national resilience have been identified for Ukraine: creation of a multilevel risk assessment system; improving strategic planning, analysis and crisis management; developing the resilience potential of local communities and regions. A formalized model of an integrated national security system is proposed, based on the principles of resilience of regional security parameters of all regions of Ukraine and a resource-oriented approach to the transition of the existing state of regional security to the desired state.

Effective innovative activity of enterprises with the dynamic economic development is possible under the conditions of timely implementation of innovative projects that satisfy and meet the requirements of the external and internal environment and contribute to building up their own potential with the orientation of the enterprise activity on the long-term prospect of development. This contributes to higher importance and role of strategic management of innovation activity of domestic enterprises. Therefore, the purpose of the article is to provide methodological and practical recommendations for the development and implementation of the strategic management system of innovative activity of the enterprise. in order to achieve this goal, the stages of the strategic management process have been specified, which are grouped into three stages: preparation for strategic management; ensuring the strategic management process; control over strategy implementation. The relationships between the stages have been described, as well as the components, the features of the activities and the sequence of actions for each of the stages. The researches were carried out using the following analysis; modeling; empirical research; systematic approach; generalization. The effectiveness of the proposed recommendations for the formation and use of strategic management of innovation activities has been confirmed by the activity results of the enterprises (Horodok Mechanical Plant PJSC, Ozon LLC, Zakhar Berkut Ski Resort), which provided a sustainable long-term competitive position in the market at the expense of the timely and correct identification of emerging strategic problems at the early stages of innovation activity.

Restructuring  is relevant for companies that have free capital and need to expand for development purposes, as well as for companies that have relatively large problems with financial results and the relevant indicators indicate the necessary changes. Motives of the restructuring may be different, the authors put forward the following reasons: operation operational synergy, financial synergy, diversification, economic motives. Restructuring is one of the key methods  for company’s financial position strengthening. Motives of restructuring are various, but the objective  is company's value increase and  the strengthening of financial  position. The authors investigate the essence  of the company's financial strategy, studied restructuring as a modern approach of company development in the crisis period, as well as the company's valuation and financial analysis methods, which were used for restructuring.

S. Kuznets's study that the average propensity to consume is a constant value were nexpected because they denied one of the basic provisions of the Keynesian theory. This fact was called "the riddle of Kuznets".  F. Modigliani and M. Friedman, using the hypothesis of the life cycle and the concept of constant income, proposed two options that explain its solution. But models should not explain, but give a method of solution. The most controversial is the indicator of autonomous consumption. In the first model, it grows, and in the second it goes to zero. Creation of a method of simulation of consumption functions based on common methodological principles for the consideration of micro and macroeconomic systems. Having constructed a model that objectively describes the activity of a separate enterprise, the primary and primary links of the macroeconomic system, we can explore the whole system. At the exit of the economic system we consider two functions of the offer - cost and cost-price, and one demand. These functions form two types of Keynesian cross, which define two points: break-even and economic power (equilibrium In a three-dimensional space a chain of transformations is considered: profit, investments, fixed assets, growth of depreciation (constant costs) and output. The condition for the formation of a "proportional development economy" - the average propensity to consume should remain unchanged, which is achieved when the marginal values of the multipliers of fixed costs and return on assets are constant. Such periods were explored by S. Kuznets.

The authors studied and analyzed various concepts and approaches to company value management. They described the advantages and disadvantages of the leading traditional approaches to assessing the value of an enterprise and proposed a model of the dynamics of the company's value, taking into account the ownership structure, explaining the mechanism of the influence of the company's ownership structure on the capital structure. Using an example, we examined the change in the company's value by individual factors and identified which factors have the most significant positive and negative impact.

The e-government application may enhance government facilities for its shareholders. Nevertheless, implementing such system faces many difficulties and obstacles. The considerable debacle of e-government inspires studies on those obstacles, especially in developing countries around the world. To examine the e-government implementation challenges more accurately, we have collected more than 50researchesreleasedafter 2010from various and multiple database sources such as IEEE Explore, Science Direct, Emerald, and Springer Link. For accomplishing our study, we have adhered to scientifically accepted top practices for researchers. According to the instructions, we have developed study objectives, in the mean time; we have used a method depending on certain criteria to achieve our study objectives. In the process of researching, we have demonstrated that there is lack of familiarity of the term e-government and there are obstacles associated with the application of an electronic system. There is a clear difference regarding the challenges hindering the implementation of an electronic government in underdeveloped nations, and these challenges differ from one country to another according to the location, culture, infrastructure, and organization conditions, in addition to social and political obstacles.the study found that the most important challenges facing the governments in implementing e-government are summarized in the organizational, political, social, and infrastructure challenges.this research aims to accomplish a thorough analysis of findings reported in the published studies regarding the challenges facing the implementation of e-government in developing countries.

The relevance of the research topic is due to the fact that in the current economic conditions, the availability of sufficient financial resources in the regions of Ukraine is a prerequisite for the formation of their strong financial potential and the basic basis for ensuring sustainable economic development of the regions. Therefore, the issues of shaping and enhancing the financial capacity of the region, as well as improving the efficiency of the use of available resources, are of particular importance today. In the work a comparative analysis of the dynamics of the financial potential of the region with the help of statistical-accounting and indicative methods is carried out.in the process of research, scientific methods were used: induction and deduction - in assessing the volume of financial potential and its effectiveness; statistical analysis - in the process of analyzing the financial potential of the region; economic and mathematical modeling - to substantiate strategic directions of formation of financial potential of the region. The result of the study is clearly defined tendencies of economic development of the regions of Ukraine on the basis of their financial potential and reasons for deepening differentiation of development.

To determine the directions of managing the intellectual capital of a university, the authors studied the impact of the knowledge economy on the education sector, analysed the most prestigious international rankings of universities and their criteria and methodologies, assessed the current state and prospects of Ukrainian universities in global rankings. The study of theoretical developments has proven the importance of the intellectual capital of the university and its ability to increase the competitive advantages of universities. Authors proposed the mechanism of institutions of higher education intellectual capital management in the knowledge economy, which provides a synergistic effect of all components of intellectual capital and will increase the competitive advantages of Ukrainian universities.

The article investigates the role of bank capital in financing reproduction processes and increase of economic growth indicators, considers the essence of the concept of “bank capitalization”, determines the structure and main sources of bank capital increase. Taking into account the fact that Ukraine and Poland have similar vectors of economic development, the current practices of increasing the bank capitalization, as well as the peculiarities of the action of the governments of the two countries in the negative financial and economic crisis, positive and negative aspects of regulatory policies aimed at restoring financial stability and resistance of the banking sector of Ukraine and Poland have been identified. The study of legal aspects of regulating the capitalization of banks allowed to generalize the requirements for the level of capitalization by the central banks of Ukraine and Poland, as well as to determine the features of regulating the capital adequacy of banks by supervisors in the context of Basel III. The structure and dynamics of the capital of banks of Ukraine and Poland during 2012-2019 have been analyzed. The relationship between the level of capitalization and the level of economic development of the country has been revealed. The peculiarities of the recapitalization of banks with the participation of the state have been clarified. The main attention has been paid to the complex analysis of the experience of capitalization of Polish banks, and the ways of its use in Ukraine have been substantiated.

Successful implementation of land reform requires the implementation of large-scale market transformations, in particular in the structure of land tenure and land use, in the field of land valuation. The article is devoted to the development of scientific and methodological bases of economic evaluation and use of land resources of agricultural enterprises, substantiation of approaches and recommendations for improvement of ecological, economic and institutional principles of land development in the conditions of new land relations. The economic mechanism of realization programs of protection and reproduction land resources is developed. Mandatory monitoring lands of agricultural significance is proposed in order to identify degradation processes, negative changes in soil condition, development of a long-term forecast of agricultural land use. Due to the fact that the state does not carry out strategic management of land resources, the rate of land degradation is growing, actions to increase soil fertility is not planned. One of the main method of monitoring land resources can be the observation of changes in their condition in the long run using five- and ten-year cycles. It is proposed to move to annual monitoring, which allows to identify the main trends in land use and apply the results to the planning and management of land potential of the country, region, company. The results of monitoring of agricultural land resources in general can be an information base for the characteristics of arable land, which can be used for the purposes of internal land management, implementation of measures to optimize land use, as well as to improve the regulatory assessment of land.

The article presents the results of a study of the nature and characteristics of investment processes in the agricultural sector (by the example of agriculture and food industry in Ukraine), as well as recommendations on the modernization of the mechanisms for strategic management of these processes. It is noted that the restoration and development of Ukraine is possible on the basis of the effective development of agricultural entrepreneurship, which can be achieved through the use of a set of interrelated measures of a financial, economic, industrial, technical, organizational and social nature, aimed at the withdrawal of such anti-crisis and restoration organizations or their achievement profitability and competitiveness. The state policy for the development of agricultural enterprises should provide for the creation of a favorable investment climate for domestic and foreign investment. The authors note that in modern conditions of development of the national macroeconomic environment, the solution of this problem involves not only the development and formulation of market strategies, but primarily the solution to the problem of creating and implementing an effective mechanism for implementing intra-industry strategic decisions. At the same time, it should be taken into account that many issues of the formation and implementation of the state policy for regulating the development of agricultural enterprises in the face of institutional uncertainty and financial instability have not yet received adequate coverage. the authors concluded that direct government subsidies for agribusiness in Ukraine are harmful. They are distributed opaque, distort competition, produce corruption and nervousness. As a result, the interest of diligent agricultural producers is declining. Corruption and opacity lead to an unreasonable increase in prices for agricultural products. Based on the analysis, it is shown that the best way of state support for agricultural production is investment in rural areas - an increase in investment costs for roads or education in rural areas. It should also be taken into account that one of the tasks of state policy is to increase employment in rural areas, therefore it is necessary to support not only individual producers, but also “non-agricultural” employment, for example, “green tourism”. Also, government support should be distributed “automatically”, and not selectively. For this, it is important to develop and implement appropriate criteria. the economic security of economic entities in the agricultural sector should be the subject of an economic strategy in the food industry. The reduction or exclusion of business entities from participation in many areas of intra-industry life creates enormous economic risks (threats) for the near and long-term prospects of the food industry. Therefore, in order to ensure socio-economic development in the food industry, it is necessary to develop and introduce intra-industry socio-economic policies that will ensure the growth of key indicators in the national macroeconomic environment.
