A.; Mashchenko, M.; Gavkalova, N.; Chernova, L. S.; Lola, Yu.The cognitive model of regulating educational migration is constructed on the basis of an oriented graph-structured scheme of causal relations between system elements. This model, in contrast to others, combines factors, taking into account their interaction, leaving, and the educational conditions of foreigners, which in balance lead to educational migration. This model also determines the effects for the country, region, university, and individual migrants. The cognitive model is the basis for developing a set of scenarios. Scenario modeling allows for the identification of possible variants for the development of a situation, ways and mechanisms of influencing the situation in order to achieve the desired results and avoid undesirable consequences, and the development of a set of measures to influence the situation. Each scenario is characterized by the initial data, the influence of management, and the obtained result. Thus, all possible variants of system development are considered and the optimal management strategy is chosen to achieve the desired goals. Three core scenarios of development (optimistic, realistic, and pessimistic) were obtained on the basis of the cognitive model of educational migration regulation. Given these scenarios, methodological recommendations can be formulated on the regulation of educational migration in order to attract educational migrants to Ukraine from foreign countries. This will promote the interests of the social, economic, political, and demographic development of the country. The implementation of the proposed measures to regulate educational migration will facilitate the integration of domestic education and science into the global system, improve the quality of education and its competitiveness in international markets for educational services, increase income, and offset the negative effects of Ukraine’s demographic decline.Документ Enterprise financial security threats: identification, assessment and forecasting models(2018) Sergienko, O.

A.; Sergienko, O. A.; Stepurina, Svitlana Oleksandrivna; Bilan, Yuliia AndriivnaДокумент Integrated tool development for managing a marketing activity of a trading enterprise in a competitive market(НВП ПП "Технологічний Центр", 2019) Shapran, Evgeniy; Sergienko, O. A.; Gaponenko, Olga; Shapran, OlenaThe object of research is a comprehensive approach to the formation of the marketing policy of a trading company to improve the effectiveness of marketing activities in the competitive market. The presented approach consists of three main stages, namely: assessment and analysis of the prospects of marketing activities of the enterprise, assessment and analysis of the internal and external environment, management of the marketing policy of the enterprise. To assess the attractiveness level of the field of activity, the Cobb-Douglas production function is used, on the basis of which a number of characteristics characterizing the economic attractiveness of economic sectors are determined. The highest performance indicators are in the area of trade, construction and financial activities. As part of the study of environmental factors, regional segmentation models are constructed using the cluster analysis method, which allows identifying stable groups of objects with similar characteristics. Segmentation allows to get homogeneous groups of regions of Ukraine on the grounds of: development level, level of investment attractiveness, level of economic activity and the need to update household appliances. The result is a group of regions with high, medium and low levels of development. The methods of analysis of variance are applied to study the differences in the product market by region. To study the internal environment, models of product sales dynamics are implemented and forecasts are made that allow to develop a set of measures to improve the company’s sales policy. To assess and predict the level of sales of goods, time-series decomposition models with the identification of components are used: trend-cyclic, seasonal, and random. The used inventory management model for improving sales policy management is adapted to the trading company based on the use of intermediate planning results, namely: demand rates, costs for ordering and storage, lead time. A hierarchy analysis method based on an expert survey on the formation of promotion policy directions is implemented. The obtained priority measures for the use of marketing budget funds, which should be aimed primarily at the development and implementation of effective marketing measures for: promotion and promotion of sales, advertising, personal sales and public relations. The results can be implemented in the activities of trading enterprises to formulate and justify a marketing development policy.Документ Justification of the implementation of self-organization processes at the micro and macro levels(ТОВ "Планета-Прінт", 2020) Dubrovina, N.; Sergienko, O.

A.; Morozova, Nadiya L.; Karpets, O. S.; Babenko, M. V.This paper proposes methodological aspects of evaluation of organization efficiency of personnel management and motivation on the bases of application of economic and mathematical tools by implementing a three-component algorithmic model. The structural divisions heads’ work effectiveness evaluation is carried out on the basis of econometric systems of structural equations that allow you to rank personality, communicative, innovative, social and corporate managers characteristics that have the greatest impact on the overall performance indicators of the bank staff among which are considered amount of attracted funds; assessment of employee's compliance with the standard; activity efficiency (number of contracts); contribution to development. The obtained modeling results confirm the hypothesis that structural unit managers need to work on the development of their communicative, innovative, personal and social characteristics. Models for analyzing the personnel motivation factors on the bases of the methodology of multivariate statistical factor analysis with initial list of 13 main indicators of staff motivation are proposed; as a result, we set up the aggregated factors that reflect the properties of several motivational components such as financial, social incentives and medical insurance for employees. The model for estimating influence of motivation factors on results of bank's activity on the bases of nonlinear econometric functions is constructed. The regression equation of the motivation factors influence on the bank total profit is obtained. The proposed model toolkit for evaluation of efficiency of management and staff motivation will allow the bank's management to improve motivation and incentives mechanisms in order to raise efficiency of stuff productivity in direction of increasing bank profitability and competitiveness.Документ Model Tools of Credit Risks Assessment of Agricultural Enterprises in International Trade(2020) Nashchekina, O. N.; Sergienko, O. A.; Sosnov, Igor; Tatar, Maryna; Shapran, EvgeniyThe paper aim is improving the methodological tools for agricultural enterprise's credit risks assessment and classification as participant of international trade market. The proposed approach differs from the existing approaches by complexity and systematicness, on the bases of usage of multilevel factor system of the borrower's assessment by local and aggregate components. The object of research is set of credit risks affecting crediting processes in agricultural sector of Ukrainian economy. The following economic and mathematical methods of scientific research were used: factor and comparative analysis (to highlight classification specific features of agricultural sector crediting), methodology of integrated rating (for rating of local components of risk), methods of factor analysis (to confirm the hypothesis of grouping of agricultural enterprises credit risks by components), hierarchical and iterative methods of cluster analysis (to distinguish agricultural enterprises classes by risk level). The proposed methodology is tested on a sample set of observations for 14 agricultural enterprises of Ukraine for 2018 year for the selected 38 credit risk indicators. On the bases of economic and mathematical tools for estimating and analyzing the aggregate system of agricultural enterprises credit risk indicators, namely the methodology of factor analysis, the hypothesis regarding the grouping and formation of agricultural enterprises credit risk classes has been improved. Five major systemic groups of external and internal risks which are specific to agrarian enterprises are identified: mortgage risks, system providing risks, system forming risks, natural and climatic risks, production risks. The obtained classes by risk level by the studied components on the basis of cluster analysis methods make possible to determine the set of critical and safe states in general and by local components and to choose effective behavior trajectory for agricultural enterprise creditworthiness increasing. The assessment results using proposed methodology laid in the bases of scenarios development of agricultural sector lending, make possible to develop a set of measures for strategic and tactical management of agricultural enterprise's creditworthiness and adjust their behavior in international markets.Документ Modeling logistic business processes and their improvements(Національний технічний університет "Харківський політехнічний інститут", 2020) Sergienko, O.
