Today, a serious problem is the formation of crisis situations in the economic development of the country (region), which are determined by a set of the various indicators. The main causes of the crisis are both external factors, that is, factors of economic globalization, and internal factors that are associated with serious imbalances in social and economic development. Each group of these factors can lead to an increase in the tension of crises, therefore, a timely assessment and analysis of the formation of crisis situations is very important. The assessment is carried out on the basis of indicators that characterize the socio-economic development of the country (regions). Changes in these indicators allow us to calculate the intensity of economic development. The aim of the work is to form and substantiate a system of indicators that characterize the economic and social development of the country based on the analysis of the current statistical indicators of socio-economic development of the country (region) and build a comprehensive integrated indicator of tension. The paper proposes a methodology for calculating the integral indicator of socio-economic tension in the country, which includes 9 main stages: collection of the indicators of socio-economic development; formation of a matrix of input data of indicators; standardization of the information space; differentiation of signs into stimulants and de-stimulants; building a standard; determination of the distances between the object and the standard; construction of an integral indicator of the tension of socio-economic development; interpretation of the integral indicator of the tension of socio-economic development. Thus, the work has formed and substantiated a system of the indicators characterizing the economic and social development of the country on the basis of an analysis of the aggregate of indicators of the socio-economic development of the country (region) in the statistical reporting and determined the integral indicators of tension separately for the social and economic spheres.

The subject of the research is a set of models of systems analysis of the educational services market. The goal of the work is to develop a set of models of systems analysis of the educational services market in Ukraine, which allow to assess the state of regional market segments; to highlight the segments which are the most sensitive to the reduction of the educational institutions network; to assess the competitiveness of educational services in the foreign market; to determine the most attractive segments of the foreign market. The paper solves the following tasks: models of classification of regions according to the level of development of the education system are developed; models for a comprehensive assessment of the level of development of the education system are proposed, which allow assessing the position of Ukraine in comparison with European countries; models for classifying external market segments by the level of attractiveness for promoting educational services of Ukrainian universities in the context of an export-oriented development model are developed. The following methods are used: systems analysis – to describe the object of research, conceptual approach and a set of tasks to be solved; cluster analysis – for building classification models; taxonomy methods, development level method – to build a rating assessment of Ukraine's position in the educational services market. The following results have been obtained: a grouping of the regions of Ukraine by the level of development of the education system has been developed, the "pivotal" regions for the formation of a network of educational institutions have been identified; a system of rating assessment of countries in the educational services market institutions has been proposed; the most attractive external market segments for the promotion of educational services of universities in Ukraine institutions have been identified. Conclusions: the implementation of the models made it possible to conclude that the composition of the "pivotal" regions for the formation of a network of educational institutions includes such regions as Kyiv, Kharkiv, Odesa, Zaporizhzhia, Lviv, Dnipro regions. Educational services of universities in these regions are in the highest demand, but these regions are also the most vulnerable to the phase of market decline. The analysis of the "substitute" effect made it possible to conclude that Ukraine is characterized by a high rating of the level of development of the education system in comparison with European countries. In the context of the export-oriented development model, external market segments that are attractive for Ukraine have been highlighted.
