S.N. Sukhov, O.A. Korelov
Management decision-making in the field of law enforcement requires a systematic analysis of both the state of the control object and the capabilities of the subject. To solve a number of management problems, the effective use of mathematical modeling methods that allow you to build, and subsequently explore the information model of socio-economic processes. In the study of the constructed model, identifying patterns in the data, possible subsequent forecasting, which is an important element in decision-making in the law enforcement sector, allows to determine the most optimal mechanisms of management influence. In determining the possible negative options for the development of events, the development of intervention scenarios in order to obtain a positive result. Building a model of information processes allows us to conduct an experiment to study the phenomenon of interest to us in conditions where the natural experiment is impossible, difficult or undesirable. In addition to the complexity of the model, an independent problem is the interpretation of the result, the understanding of the practical meaning of the solutions. It should be understood that the use of mathematical modeling for the development of management solutions in the field of law enforcement is just one of the tools with limited capabilities, which should be used only in conjunction with the results of research in other areas.

Y.E. Lvovich, A.V. Pitolin, G.P. Sapozhnikov
The article justifies the necessity of building various classes of mathematical models of complex systems as well as the relevance of a multi-method approach to the processing and modeling of monitoring and rating information, due to the variety of management tasks and resource efficiency optimization management of a non-profit educational organization in combination with rating management. The starting points are tentatively reduced sets of input indicators influencing the output indicators of a management unit functioning. It is based on time series forecasting on the base of additive and elementary functions. The dependence of the output performance on the input ones is determined by the regression model with the inclusion of time variables. The transition from a regression model to a neural network model is carried out, to improve the accuracy of forecasting for the purpose of managerial decision making at a certain planning horizon. The transformation procedure of initial time series into statistical samples of their prognostic estimates followed by randomized training sample development is proposed. The paper also demonstrates that the multi-method approach to the modelling provides a solution to a number of tasks concerning complex systems resource efficiency management.

MANAGEMENT OF FUNDS ALLOCATION OF AN EDUCATIONAL
The article presents the expert optimization approach to improving the efficiency of funds allocation management in an educational organization, which is a combination of intelligent technologies, analytical and numerical methods. It is suggested that managerial decisions should be focused on the objectives of funds allocation and development strategy of the educational organization. Achievement of these goals is provided by the use of expert-optimization approach in the tasks of funds allocation between the budgeting objects. The functional funds allocation among school business processes is carried out with the use of an expert knowledge model of transforming the results of a SWOT analysis of building membership functions of vague relationships. The budget allocation of income and expenses between the centers of financial reporting is implemented on the basis of expert assessment with the use of linguistic variables and a formalized model of multi-alternative optimization. For the allocation of the investment budget among the educational organization development projects, a preliminary expert analysis of management accounting mechanisms with a transition to the multi-alternative optimization task is used.

The purpose of the article is the enhancement of the instruments for automation of the qualitative research of the dynamic system and forecasting values of the parameters, which characterize organization activities in the economy (particularly in the field of management of housing and communal services). In this article, the problem of automation of the analysis of the phase trajectory of the dynamic system is solved (organization of management of housing and communal services), using the qualitative theory of dynamic systems. The research is relevant due to the insufficient level of automation of qualitative research of dynamic systems in the economy with the economic interpretation of research results. Methods of qualitative theory of dynamic systems, which are used, allow forecasting the state of the dynamic system without numerical simulation (for example, integrating differential system, which is a model of the dynamic system). In the article is presented technique, in accordance with research of the phase trajectory of the dynamic system using the software application, was conducted. Types of phase points in the phase plane in accordance with character of behavior of the phase trajectory plane in the neighborhood of the projection of the phase point were identified. By the example of the phase trajectory analysis, which characterizes activity of organization of management of housing and communal services, opportunities of the software application, building of projection of the phase trajectory into the three planes occurs. It was identified that in the phase planes equilibrium states as «stable node» and «stable focus» are missing, but there are equilibrium states such as «unstable node», «unstable focus» and «saddle». The example of detection of the «field of attraction» of the phase trajectory in phase plane is given. Types of «fields of attraction» were identified and economic interpretation for the «fields of attraction» was given. The main directions for the enhancement of the developed software application functionality are formulated. The materials of the article present the practical value for the experts, who are forecasting state of the organization in economy, and particularly in the housing and communal services.

HUMAN VALUES IN THE DIGITAL AGE
A. M. Factor, S. G. Kamolov, A. A. Nikandrova
Human values and systems of such values play an important role in human life and society. The individual value system is always linked to the values inherent in society. The article discusses the concepts of values from the point of view of different researchers. It is shown that economic development, cultural and political shifts are interrelated and go hand in hand with the transformation of human perception, human norms and values. In modern postindustrial societies, traditional values are contrasted with secular-rational values. People with such values pay less attention to religion and traditional family values. The digital age in which we live is different from other historical periods. It is shown that the mass digitization of our lives makes people adapt to the new reality. As part of the research, the authors conducted an interactive survey on modern values in the digital age. At the beginning of the survey, it was proposed to select five values that correspond to the most important. Further, respondents were asked to answer the question whether it is important for colleagues to have similar values. The respondents were then asked to choose between the political and economic condition of the country as the most significant factor influencing human values. At the end of the survey, respondents were asked to select five values that they could call typical of the digital era. An interesting finding is that while those in charge consider the family to be one of the most important values, they do not believe that this value will be equally important in the digital age. Thus, an assessment was made of whether classical values will remain unchanged or become inaccessible to people in the digital age.

With the purpose of ensuring highly reliable information processing in practice at assessment of stability of functioning of the security systems considered from positions of information structures in the conditions of negative impacts, it is necessary not only to develop new models and algorithms of steady interaction of elements of the specified information sets, but also to consider requirements to efficiency of the information processes proceeding at the same time. Increase in amount of negative impacts on elements of security complexes demands modernization of systems of parrying of negative impacts and also carrying out the analysis of stability of functioning of this sort information structures. The improvement of information structures and optimization of information processes made on the basis of development of adequate models of functioning of systems of complex safety of objects of special importance in the conditions of factors of external influences is a scientific and technical task relevant now which implementation will allow to minimize lag of rates of development of the security equipment and technologies from dynamically improved instruments of destabilization of elements of systems of protection of objects of special importance. Development and the solution of adequate mathematical model of interaction of information structures of security systems and negative impacts are intended to describe dynamics of evolution of their elements on the phase plane of space and taking into account integrated representation of stability conditions and also the second method of Lyapunov to create mathematical model of steady management of information process of interaction of elements of the specified information sets. The task of the analysis of phase portraits of a condition of security complexes as information systems is connected with a research of the attractors representing areas (the phase vicinities) of space consisting of set of concentric circles in the form of a set of the points which are attracting trajectories of evolution of elements of information structures of security systems and indicating areas of their steady functioning.
