Research purpose: is a substantiation and modeling of appropriate norms of physical readiness of youth for service in the army. Materials and Methods. The expert group included 21 specialists (whose field of activity is physical education, special training, physical training in the security and defense forces). The following research methods were used to solve the problem posed in the work: theoretical analysis, comparison, systematization and generalization of materials of scientific, historical, methodical literature and guiding documents; expert evaluation (Delphi and analysis of Saati hierarchies); methods of mathematical statistics. Results. It is determined that even simple statistical methods in combination with expert information when choosing promising solutions often give better results than accurate calculations with a focus on averages. A comprehensive approach using peer review (Delphi), a method of modern theory of hierarchical systems Saati allowed to determine the structure of the projected model of physical fitness of young people for military service. The structural interconnected components of the predicted model with the corresponding weighting factors are the level of formation and development of general and special physical qualities (ρ1 = 0.411), the level of formation and development of special physical qualities (ρ2 = 0.235), the level of acquisition of military applied motor skills (ρ3 = 0.216), the state of the cardiovascular system (ρ4 = 0.138). Conclusions. The presented structural predictable model of integrated assessment of physical readiness of youth for service in the army allows to define limits of levels of components and to estimate their level of formation in points from 1 to 12, and also to correct the maintenance of means of physical training depending on such components which lag behind a proper norm.

Introduction. Hierarchical control in complex multilevel systems has been studied since the period of classical cybernetics. At that time, basic definitions and concepts were introduced. It is time to start remembering those achievements because those decisions can already be implemented. However, the situation is constantly changing (evolving), so those tasks are perceived differently today. And the question arises as to how these old developments will progress, whether they will be used? Purpose. The purpose of this work is an attempt to predict the development of hierarchical multilevel control systems in the future and how it depends on the latest technologies that determine their software-hardware complex (SHC). Result. The analysis of the essence of the multilevel hierarchical management system, its features and additional requirements for the software-hardware complex, the current state of hierarchical management systems, the impact of advances in IT technologies and theories on the features of hierarchical management are carried out. The current state is studied on the example of NATO hierarchical systems. Based on the forecasts of the development trend of IT technologies, the forecast of trends in changes in hierarchical multilevel control systems is proposed. Conclusions. As a result of the analysis of the essence of hierarchical multi-level management systems, the current state, and forecast of the development of IT technologies, the authors made the following conclusions: – the hierarchical structure of a complex multi-level system will be in demand in the near future; – Hierarchical systems will consist of standard components with elements of artificial intelligence that controls the components; – the process of creating a hierarchical system will be simplified, so it will be possible to use ready-made solutions.

A system of operational control of psychophysiological indicators of operators is presented. It includes a set of test methods for selecting psychologically compatible operators of high-responsibility systems. The selection of operators on a PC is carried out. The results of electronic protocols in narrative and graphical form are given. After that, the method of selecting psychologically compatible operators of highresponsibility systems is applied. It uses a mathematical model selection of PC-based operators using regression analysis. The coefficients of this model are taken as a selection criterion. The maximum permissible maximum criterion corresponds to the coefficient of the mathematical model of the work of operators with a relatively high level of professionally important qualities. And the maximum permissible minimum criterion corresponds to the coefficient of the mathematical model of the work of operators with a relatively average level of professionally important qualities. In future, the calculation is completed according to the developed algorithm for the selection of psychologically compatible operators. Operational control of the psychophysiological state (PFS) of operators is performed with the control support of marks from the target in optimal conditions using a hierarchical system of group tracking on the example of links of the automatic control system. As a criterion for assessing the stability of the PFS operators at the time of the control, the range of changes in the value of the RMS error when accompanying the control mark is taken.

The purpose of this paper is to study the patterns of the formation of output values in hierarchical systems offuzzy inference. Hierarchical fuzzy inference systems (HFIS) are used to aggregate heterogeneous parameters during the assessment of the state of various elements of complex systems. The use of HFIS allows avoiding the "curse" of the dimension associated with a strong increase in the number and complication of the structure of the production rule, which is characteristic of conventional fuzzy inference systems (FIS), which aggregate the results of interaction of different values of input variables in one knowledge base. As part of the research, numerical experiments were carried out to study the features of the formation of output patterns in HFIS, based on FIS using the Mamdani and Takagi-Sugeno algorithms. As a result of the experiment, it was shown that the output values of the studied HFIS tend to be grouped in the region of fixed values, and the output pattern itself acquires a stepwise character. The revealed property allows using HFIS to distribute the objects of the analyzed sample into groups of states. This property can be used to solve problems of distributing objects into groups in conditions when it is difficult to form a training sample for machine learning methods, but at the same time there is knowledge of the expert group about the features of the functioning of the object of research. Additionally, the paper investigates the features of the formation of output patterns depending on the parameters of the membership functions describing the input variables in HFIS, which are based on FIS using the Mamdani algorithm and HFIS, which are based on FIS using the Takagi-Sugeno algorithm.

The first chapter covers the outgoing epoch of the multinational empires and continental Middle and Eastern European colonial powers, which experienced the zenith of their expansion of power and their collapse. The period between the turn of the century and the outbreak of the First World War was the golden age of European imperialism. It also introduced the heyday of nationalism. The nineteenth differed from preceding centuries by establishing increasingly strict boundaries in the interest of demarcating state and nation in two regards: in territorializing state authority and defining who was subject to it. Citizenship became the pre-eminent legal tool for marking the bounds of nation-state authority over persons. Alongside the particularly intense manifestation of national and ethnic criteria for inclusion and exclusion, new hierarchical systems, based on citizenship, grading affiliation based on ethnicity and race developed, redefining the relationship between colonizing and colonized nations on the European continent as well as in the overseas colonial territories.
