Публікація Applied aspects of proactive modeling of innovative-investment processes of complex hierarchical systems: enterprise–region–state(Ljubljana School of Business, Slovenia, 2020) Sergienko, Olena; Tatar, Maryna; Bilotserkivskyi, Oleksandr; Baranova, ValeriaThe paper proposed a proactive mechanism of innovative activity management of complex hierarchical systems (CHS), consisting of successive stages of assessment, analysis, planning, forecasting and innivative activities regulation at the levels of an enterprise - a region – the state. Specific tasks of the proposed mechanism require model support, in connection with which the author has developed a set of models for the proactive innovation management SYSTEM. The valuation models and analysis of the innovation capacity and innovation outcomes of socio-economic system of a region (SESR), which allow, in contrast to the existing models, to compare the results of innovation activities and innovation potential and to make a conclusion about the effectiveness of the existing potentia use are built. The model of evaluation of innovative projects of business-industrial structures (BIS) efficiency based on the use of fuzzy set theory and methods of multicriteria problems solution, which allow to consider the risks arising at each stage of the innovation life cycle. The set of models of economic evaluation of SESR innovative activities based on panel data, which allows to estimate the resource use efficiency in the implementation of innovative activities and to predict the consequences of managerial decisions on stimulation of innovative activities is proposed. The simulation model scenarios of stimulation of SESR innovative activity, which allowed the simulation of scenarios to stimulate and assess their performance in order to select the best scenario of innovation regional systems according to the criteria of profit maximization, maximizing the number of innovative-active BIS and maximize the gains integrated assessment of SESR innovative activity results are designed. The simulation results allowed to determine the best scenario for promoting regional systems and the state as a whole.Публікація Modeling of factors of production interaction and efficiency of their usage in enterprise competitiveness management(Ткачук А. В., 2017) Sergienko, O. A.; Tatar, M. S.; Golofaieva, I. P.Публікація Banks financial security management: modeling tools(Університет банківської справи, 2017) Sergienko, O.; Tatar, M.; Morozova, N.; Galych, R.The article is devoted to the development of the complex of economic and mathematical models to support decision–making on managing commercial banks financial security. Aggregated model of management system of commercial banks financial security is presented. Basic conceptual scheme of the bank’s financial security management is developed. The proposed modern modeling tools on the bases of multivariate, econometric, simulation methods and decision making methods make possible to do integrated complex analysis at all levels of the banking market. The results of research in particular assessment and analysis of the survival and spread of crises in the banking market, the research of the particular bank financial security level dynamics in terms of external and internal factors are the basis for the formation and selection of scenarios of financial security ensuring taking into account the features, opportunities and competitive advantages of each bank. The implementation of the proposed modeling tools of financial security makes possible to improve the efficiency and effectiveness of the commercial bank activity and its financial security level.Публікація Сointegration evaluation tools for enterprises strategic development system upgrading(Університет банківської справи, 2020) Sergienko, O.; Shapran, O.; Tatar, M.; Bilotserkivskyi, Oleksandr ; Druhova, O.The paper proposes tools for improving the strategic management system for assessing the processes dynamics and the level of their intensity and non-stationarity by local resource components of industrial enterprise as indicators of organizational and economic development and forecasting its change, as well as determining the structure of the strategic management system of enterprise development with emphasis on its resource communication component that will improve the efficiency of information exchange in the management process in the current context of increased importance of information resources as important elements that provide business entities competitive advantages. In this paper, the complex of models of research of development dynamics of enterprise activity spheres is built, which unlike the existing ones takes into account the non-stationary character of the behavior of these processes. This complex is based on the methods of multidimensional analysis, econometric modeling, decision-making. This complex contains the following steps: formation of the information sets of the company’s indicators in the main activity spheres; research of development dynamics of enterprise activity spheres on the basis of building of local and complex integral indicator of enterprise development level; simulation of non-stationarity dynamics of activity spheres on the bases of building and analysis of ECM&VAR-models — cointegration and vector autoregressive models; simulation of the enterprise development priorities on the bases of ECM&VAR-models analysis. For improvement of the strategic development management system, a conceptual scheme of the interconnection of processes, tasks, and models was developed, which provides the solution of the following main tasks: factor study of development trends, study of the internal environment and potential for key business factors and its development dynamics and implementation of adequate management decisions for increasing systems activity effectiveness as a whole.Публікація Modeling of threats to enterprise financial security(Національний технічний університет "Харківський політехнічний інститут", 2019) Sergienko, Olena; Tatar, M.
