METHODS OF WAVELET ANALYSIS AS A TOOL OF ECONOMIC SECURITY
DescriptionIn the context of the objective existence of risk and economic, human and other losses related with it, there is a need in a specific mechanism, which would allow the best way to predict the damage caused by the emergency. These risk management tools in emergency situations are monitoring and forecasting. In this research work, time series are used as a signal; they contain information about the number of fires in the Karachayevo-Cherkessia in the period of 1983- 2014. In solving the problem, the authors applied wavelet tools for data cleaning from noise, anomalies that have provided quality model building reliable forecast - possible number of fires in one quarter ahead. This example shows that for the construction of this forecast there is no need for a rigorous mathematical model specification, which is especially valuable in the analysis of poorly formalized processes. We have noted that most of the tasks in emergencies fall into this category of processes

PREDICTION OF A FINANCIAL MARKET EVOLUTION ON THE BASE OF SOFTWARE TOOLS FOR LINEAR CELLULAR AUTOMAT
DescriptionThe work used methods of system analysis, monographic, structural and logical, economic-statistical, mathematical continuous and discrete, settlement and constructive methods as well as software tools of linear cellular automata. Usage of each method was based on their functionality, thus ensuring the accuracy of the findings and scientific positions. In this article we attempt to predict the dynamic behavior of the financial market elements, to use on the basis of a linear cellular automaton computer tools and methods of nonlinear science for adequate numerical reflection measure various risks, primarily financial and economic risks, as well as to show the power of computer graphics, computer mathematics system linear cellular automata, to emphasize an important philosophical role of visualization. The authors of the work programmed linear cellular automaton based on Python 2.7 software platform in the form of application. The program validates the predictive model on the adequacy of the selected coloring, is forecast error and builds polygons predictive model and input data on the same graph. The proposed research area is relevant to the processes in the financial and economic system, bringing in useful innovative elements in the generalized forecast that do not exist in continuous classical methodology

ANALYTICAL TOOLS OF VECTOR RISK ASSESSMENT OF THE FINANCIAL MARKET
DescriptionIn rapidly changing conditions of the modern world, analysts and decision makers are in need to use new formal means of analysis and evaluation of alternatives problems. This work is dedicated to the development of such tools. The article presents a detailed analysis and technical and economic characteristics of the subject area - the financial market and its specific components - the value of a time series of gold, silver, palladium, platinum, and two kinds of exchange rates: EUR / RUB, USD / RUB. The authors have proposed a 5-criteria economic-mathematical model of the main components of the ranking of the financial market. The authors argue the impossibility of using a single integrated set of criteria for the replacement of the criteria or the use of criteria convolution procedures as the standard procedure of solving the problem of multi-criteria optimization. It demonstrates that such criteria as criteria for "risk" must be considered as an estimate of the degree of deviation from the expected value of the possible values of this criterion. The practical significance of the results is determined by the fact that the main points, conclusions, recommendations, models and methods can be used in order to improve the management and planning of development strategies of banking systems, trading platforms, as well as by developers of information and analytical systems to support management decisionmaking

Description
Development of monitoring of the behavior of financial market, simulation, analysis, visualization, prediction in modern conditions is connected with a consistent increase in their level of formalization. The basis for this process is the requirements of significantly changed (in the direction of increasing) stochastics, turbulence, volatility, financial and economic processes. Particular relevance in the analysis of behavior of economic time series elements of the financial market is now becoming more systematic development of diverse, interdependent and mutually complementary economic and mathematical models. The models are linked, they are operating on the same source material, and their selection has improved the representativeness of the algorithms of modern economic processes of the financial market, which is important for transformational (transitional) market economies. In the article it is shown that the proposed usage of instrumentation and mathematical methods represent essentially new base for forecasting of discrete evolutionary processes

RESEARCH "PLATFORM" OF SYNERGISTIC PREDICTION
DescriptionThe lack of a unified research platform and tools for various sectors of Russian economy, allowing to take into account the specifics of the object of study, significantly slows down and complicates the decisionmaking processes, at the same time thereby reducing their efficiency, which is even more negative in terms of the need of quick decisions of the tasks on import substitution. Scientific essence of the proposed research can be formulated in the form of innovative unified research platform, showing the interrelated causal system components, theoretical and practical, analytical and experimental units, productive activities which are scientifically proven smart products for various sectors of the Russian economy. The constantly changing economic environment makes to answer its idempotent mathematics and information paradigm, theory, methodology. Here it is important to select the structure and rationale of the proposed research mathematical "platform". A new, different but mutually complementary multi-criteria approaches, a set of economic-mathematical models and modern mathematical and instrumental constructs, monitoring, comparison, and generalization of the results is needed. In the article it is shown that the proposed use of instrumentation and mathematical methods represent essentially new base for forecasting of discrete evolutionary processes

05.13.18 Mathematical modeling, numerical methods and software complexes
DescriptionIn the process of formation of nonlinear dynamics, the scientific society was able to refute the classical mechanisms of Newton-Laplace by justifying the chaotic nature of the phenomena of the world. However, despite the emergence of new mathematical models and tools, forecasting of nonlinear systems is a difficult task, as not only the quantitative and qualitative characteristics of the factors affecting the system are unknown, but also there is a problem of a small amount of information for forecasting. In this article, the authors consider the linear cellular apparatus as a tool for prediction the final state, to which the system will come based only on its output indicators of previous years. Since the use of a linear cellular automaton for prediction of nonlinear systems is an assumption of the authors, it should be tested on the series of stochastic systems exposed to different risk factors, which together give either a positive response of the system or a negative one. An example of such series is the time series of yields, as it is affected by climatic conditions, the appearance of which, in turn, is also difficult to predict. Prediction of stochastic systems using linear cellular automaton really makes it possible to get adequate and visual models. Due to the fact that the forecast model has a discrepancy with the real result of 0-15% (both positive and negative), the conclusion is that the predicted value will help either to take measures to ensure that the real value in the future is not lower, or to make sure that the decisions and measures taken are correct, when a value is higher than the forecast
