The article highlights the business process management system in food industry. The subject of the research is the theoretical and practical aspects of managing business processes in the food industry. The authors explain the concept of "business process" and methods for achieving its improvement goals. The author’s scheme for managing business processes in the food industry in the context of economic transformations was developed and implemented. The in-troduction of a process approach requires efforts and resources for identifying business pro-cesses, their analysis, drawing up models of business processes. The analysis of business pro-cesses in the food industry of Ukraine at a macro level is carried out, including: an imperfect tax system; the mechanism imperfection of state and customs tariff regulation of food mar-kets, the low level of financial support from international organizations, the low level of state support for agribusiness entities; decline in employment and rising unemployment; growth in international migration; low competitiveness of Ukrainian food products and barriers to international food trade. Methodical approaches for determining the regional strategic potential of food safety are also proposed. The calculations of the regional potential of food safety are car-ried out using the data of the Black Sea region in Ukraine as an example. The main prerequisites for the formation of a food safety system have been identified and justified. The organization’s transition to clear and efficient processes to achieve the objectives with optimal costs in the food industry; high flexibility and adaptability of the control system, due to the large self-regulation of the system and natural customer orientation; high dynamism of the system and its internal processes, due to the strong vertical integration of resource flows and a common interest in increasing their circulation; simplification of coordination, organization, control procedures and the possibility of deep integrated automation of food production; high motivation in ensuring the production of quality and competitive food is discussed.

This research aims to improve a methodic for evaluation of economy’s competitiveness through theoretical-methodological substantiation, forming and calculation of integral indices of innovative technological competitiveness across the regions of a country. The relevance and indispensability of reinforcement of economy’s competitiveness on innovative technological foundations are also substantiated. Available methodical approaches in economic literature and competitiveness rankings and indices used by leading international economic organizations, namely in innovations and high technology domains, are generalized. Authors’ methodic of calculation of integral index of economy’s innovative technological competitiveness is suggested. Integral indicators of provision of innovative technological activity with resources, innovative technological activity and efficiency of innovative technological activity across regions (on the example of Ukraine) are calculated for 2009-2018; conclusions regarding the preconditions, capacity and availability of tendencies of innovative technological activity in oblasts (regions) of the country are made. The paper explains that each of the components of innovative technological competitiveness of the country’s economy had almost equal input in forming of its integral index – provision with resources, capacity and efficiency of innovative technological activity. In the first place, it is an additional argument in favor of the model’s reliability, and in the second place, it brings into the fore the importance of public policy in terms of improvement of resources maintenance of innovative and technologically active companies, boosting of innovative technological activity and increasing of its efficiency and contribution to general economic growth of the country. Strategic priorities of state policy of reinforcement of the economy’s innovative technological competitiveness are substantiated.

This paper deals with retrial queues of the |MQ/M/c/∞|- type in which the rate of input flow depends on the number of sources of repeated calls and each call has only one retrial attempt. That is, if a call fails to enter the server facility at the retrial attempt, then it leaves the system without service. The existence conditions of stationary regime and the vector-matrix of the stationary probabilities of the service process are represented. This representation uses an approximation of the initial model by means of the truncated one and the directs passage to the limit. For these systems a threshold strategy for the rate of input flow is used. The multi-criterion optimization problem for finding optimal strategy of control is considered. The quality functionals of the optimization problem are represented through the stationary probabilities.

The paper shows the results of an empirical study on the optimization of polymer waste supply chains based on the circular economy in Ukraine. The research shows that the main links in the activity should be harmonized for quality and quick optimization of polymer waste supply chains, including the processes of collecting, sorting, treatment, processing, and recycling of resources for maintaining the quality by total cost reduction. The research argues that the circular economy that stipulates the easy processing, recycling, disassembling, and restoring of products replaced the traditional linear model “take, produce, and throw out” that has dominated the economy by now. The study shows that the transformation of supply chains in production ecosystems forms competitive advantages at the enterprises that allow them to be more productive through efficient use of resources.

The essence of administrative and territorial reform and decentralization reform in Ukraine is to move away from a centralized model of government in the state, ensure the ability of local self-government and build an effective system of territorial power organization in Ukraine based on the principles of subsidiarity, omnipresence and financial self-sufficiency of local self-government. The purpose of the article is to identify areas for improving the effectiveness of the administrative-territorial reform in Ukraine based on assessing the results of its financial decentralization component. Peculiarities of changing the territorial basis of local self-government in Ukraine investigate the necessity of moving from a voluntary amalgamation of territorial communities to the stage of their formation according to clearly defined criteria and providing opportunities for the development of such communities in the future. It focuses on the need to consolidate areas and change the system of interaction of the subregional level with the amalgamated territorial communities at a basic level.

The influence of military-political instability at the state security has special consequences and cannot be ignored. That is why the methods of economic security calculations should be adapted to modern conditions. Significant changes in economic, political, social conditions in Ukraine because of the influence of military events cause the necessity of developing approaches to calculations of economic security level. The article aims at analyzing active methods of calculations of economic security level to adapt their indicators to actual economic circumstances in Ukraine and the world. Indicators of the economic security have been composed of budget, money-credit, foreign exchange, debt, known banking financial market security, banking security. Every component of economic security has factors of war influence, which, as a result, correlates with the integral indicator of economic security. The relevance and indispensability of reinforcement of the economy’s competitiveness on security foundations are substantiated. The authors’ methods of calculation of an integral indicator of economic security have been suggested. A taxonomic indicator is used to measure the level of security. Conclusions regarding the preconditions, capacity, and availability of tendencies of economic security in regions of the country have been made. Strategic priorities of the state policy for reinforcement of economic security have been substantiated.

The research is devoted to the adaptation of theoretical and applied organizational grounds of favorable investment climate based on the establishment of an efficient mechanism of investment capacity increase in Ukraine. The main aim of the paper is to substantiate the mechanism of forming a favorable investment climate as the basis of investment capacity increase in Ukraine. The paper verifies the authors’ hypothesis on the adequacy of the substantiation of the mechanism of favorable investment climate forming as the basis of investment capacity increase leading to the substantial improvement of Ukrainian positions in international rankings. The dependence of Ukraine’s investment climate on the formed mechanism of its development is confirmed, and the necessity of its improvement is emphasized. The paper proves that forming of the favorable investment climate as the main precondition of boosted development, reproduction, and efficient use of investment climate at all levels is one of the most important strategic tasks that Ukraine faces. Economic, institutional-legal, and organizational-administrative mechanisms and implementation tools directed at improvement of the investment climate in Ukraine and the creation of conditions for investment capacity growth and its efficient transformation into an investment product are systematized.

The paper aims to develop a model for measuring economic system management efficiency of the Black Sea region of Ukraine through the context of sustainable development. The model includes the rates of social and economic efficiency, productivity, and performance. The proposed approach calculates the region’s economic system management efficiency. The respective evaluation criteria are systematized: economic and social efficiency of the region’s economic activity, productivity of the use of resources, and performance of the management system. The system of evaluation indicators by each criterion and mathematical apparatus to calculate them are suggested. The paper suggests methodical approaches to evaluate the economic system management efficiency in the region under transformation. They help determine the current level against similar indicators achieved within the country and the tendencies influenced by regional factors, form the “economic system management profile”, and identify the strengths and bottlenecks.

Ensuring household food security should be a priority goal of state policy. The level of ensuring household food security reflects the state of the country's economic development and the effectiveness of agricultural policy. Household food security is achieved by ensuring a high level of purchasing power of households, which is possible by increasing income. Savings are the “safety cushion” for households during the financial and economic crisis caused by the coronavirus pandemic. The level of household savings is important both for the households themselves and for the country's economy, since savings, on the one hand, help to avoid hunger during crises, and, on the other hand, are an important investment resource for the country's economy. That is why assessing the level of household savings and identifying factors affecting savings are important aspects of building an effective government policy in the field of food security.

The global process of society information has covered almost all countries of the world and is currently the core of scientific, technical and socio-economic development. The effectiveness of the power exercise in any state depends on its information support. Indeed, without information, successful political structure, the development of mass political consciousness as well as the interaction of the subject and the object of government are impossible. That is why this research aims to improve the methodics of evaluation of informational security through theoretical-methodological substantiation, forming and calculation of integral indexes of its competitiveness of a country. Global economic crisis had consequences for almost every country and cannot be ignored by any conditions, that is why the methodic of informational security calculations should be adapted to modern economic conditions. Cardinal changes in political, economic and social conditions in Ukraine causes inaccessibility of approaches to information security level calculations and particularly in the national security system. In modern scientific schools the questions of effective informational security have not been sufficiently studied. The aim of this article is to analyze active methods of state informational safety level calculations in order to adapt their indexes to actual global circumstances in Ukraine and in the world. Integral informational security have been composed of such components (indicators): income of the broadband Internet access market, dynamics of broadband Internet subscribers (connections), penetration rate of fixed broadband access (number of subscribers per 100 people), dynamics of Internet penetration (percentage of Internet users to the total population of the country), Network Readiness Index of the country, ICT Development Index of the state, Global Innovation Index, capital investments in intangible assets of Ukraine (that is, in software and databases). Every component of informational safety has factors of relevance and indispensability of reinforcement of national competitiveness on security foundations are substantiated. A taxonomic indicator is used to measure the level of informational safety. The paper proves that each of the components of the state informational security has almost equal input in forming its integral index.
