Description
The article considers brief theoretical information of the wavelet transform and the methods of identification of nonlinear time-varying systems using multi resolution wavelet transform. The methods of data processing based on wavelet transformation are widely used in recent times. Wavelets have significant advantages compared to Fourier transform because wavelet transform tells you about not only the frequency spectrum of the signal, but also on what point in time came one or another harmonic. With their help, you can easily analyze intermittent signals or signals with powerful bursts. Moreover, wavelets allow us to analyze data according to scale, on one of the preset levels (small or large). The unique properties of wavelets allow constructing a basis in which the representation of the data will be expressed with just a few nonzero coefficients. This property makes wavelets a useful tool for data packaging. Small expansion coefficients may be discarded in accordance with the selected algorithm without a significant impact on the quality of the compressed data. Wavelets have found wide application in digital signal processing and data analysis. There are two classes of wavelet transforms: continuous and discrete. In the article we have implemented the discrete wavelet transform with the resulting output distribution on a 3D graph. The algorithm and the results of converting a time series of indicators of integrated industrial systems of sugar subcomplex in agro industrial subcomplex. The methods of neural network modeling for improved accuracy in predicting high-frequency oscillation are applied in the research. The method of determination of cyclic patterns based on coefficients of the wavelet transform has been proposed

MATHEMATICAL MODELING IN THE SYSTEM OF STRATEGIC PLANNING OF ECONOMIC SUBJECTS IN THE TOURISM SPHERE
DescriptionThe sphere of internal tourism is one of the state priorities of the Russian Federation. The development of tourism in the Crimea will ensure the integration of the region into the Russian economy. The main instrument of using the competitive advantages of the tourist destination is Crimea - public-private partnership (PPP). The state has formed a legislative base for the use of PPP. The main role in the dynamic development of tourism business belongs to business entities. For the hospitality industry, the challenge is to build an effective management system in which strategic planning plays an important role. The analysis of the strategic planning processes at the level of economic entities in the hospitality industry revealed a number of problems, one of which is the failure to use progressive methods of strategic planning, including mathematical modeling. The purpose of the study is to determine the directions for improving the strategic planning of economic entities by developing a qualitative model of the organization's development that will allow to form an information base for making sound strategic plans. To determine the construction of a qualitative model of the development strategy of organizations in the sector under study, it is proposed to use a number of average industry indicators obtained by summarizing individual indicators: the efficiency of economic activity (Y); financial stability (X). The trend modeling (Y) indicates positive moderate dynamics, while the generalized indicator Y reaches 55.7826 in 2021. Similar results were obtained in modeling the generalized index of financial stability. Both analyzed indicators X and Y change the direction of their dynamics to the opposite - upward, starting from 2016, which indicates a favorable industry-wide situation. The results of the analysis will make it possible to increase the validity of managerial decisions when formulating strategic alternatives and choosing the optimal development strategy

DEVELOPMENT OF A DECISION SUPPORT SYSTEM FOR SUSTAINABILITY ASSESSING OF A COMPANY
DescriptionSustainability of enterprises plays an important role in the economic and social life of all industrially developed countries. Despite numerous publications devoted to the analysis of the sustainability of organizations, there are still ambiguous approaches to the methods of analysis for different authors. In addition, for companies of different industries, forms of ownership, geographically located in different regions of the border, the methods and indicators for assessing sustainability can vary considerably. In this connection, there is a need to develop a decision support system that would allow the most efficient assessment of the sustainability of the largest possible range of enterprises, with the possibility of adjusting and flexibly tuning as many parameters as possible. The article describes the architecture and algorithm of the DSS, which implements the following model of initial data generation in its functional; Model of formation of a tree-like structure of groups of indicators on the basis of which the stability is assessed; Model for specifying the fuzzy sets belonging to the recommended values of the indicators; Model for calculating the values of groups of indicators and their fuzzy estimates; The model of graphical interpretation of the organization's sustainability assessment. The developed system was tested on the basis of the company called Antey LLC

Description
The approaches to the intellectual capital evaluation and its components, such as structural capital, client capital and human capital of the agro-industrial complexes’ enterprises are revised in the article. The problems of the quantitative evaluation of the human capital, the client capital and the organizational capital are revealed for enterprises of the agro-industrial complexes. The examples of the structural, client and human capital’s components are proposed. The authors propose the method of the evaluation of the enterprise potential based on the development of the evaluation of the enterprise’s market value, regarding the influence of the human, client and organizational capital on its process. To develop the income approach it is proposed to regard the sum of the net present value of most preferable projects and to regard the potential residual value of a particular subject to the end of its projects’ planning period. The implementation of proposed method of potential’s evaluation allows estimating intellectual capital for expanded range of enterprises including the companies of the agro-industrial complexes. Moreover, it helps to solve tasks to potential dealings of mergers and acquisitions’ evaluation in the sphere of the agroindustrial complexes, as well as the evaluation of dealings devoted to the negotiations of some parts of company’s assets

Description
In the article, we analyze the measures that the lawenforcement authorities of the Soviet Russia and the USSR undertook against the process of bringing the criminal income into the economy of the country and using it for the destabilization of the economy and supporting criminal activities. This work reveals the true essence of criminal funds and the degree of its danger to the state and society. The author suggests that the present-day crisis in the state and political order is, largely, related to the criminogenic component of the country development, i.e. the criminal revolution in Russia in the mid 90-s of the XX century. The criminality has always been a serious problem for the society, but only in some countries it reached the level when it became a threat to national security. The factor contributing to such situation is, in the first place, the lack of action on the part of the society and the state. This allows the criminality to penetrate in all social and public institutes and create the political and economic chaos. For obvious reasons, such social context results in the dissolution of the state and the formation of smaller state structures, the introduction of external control, the loss of sovereignty and the annexation of its territories by more powerful states

Description
In the context of implementing programs on reducing budget expenditures for the social sphere utilities, it is urgent to intrude renewable energy sources into the practice of their energy supply. However, despite all their diversity, not all constructions based on renewable energy sources can be used under conditions of urban development. Besides, the mutable nature of the solar radiation coming on the Earth's surface requires specific forecasts and calculations of its intensity. Accurate estimation of the area solar energy potential of the generating plant proposed location allows not only to justify its parameters at the design stage, but also to predict its operating mode and to evaluate its technical and economic efficiency. The purpose of the article is to estimate the level of solar radiation for Volzhsky, Volgograd Region, at the initial stage of designing and justifying the implementation of power plants transforming renewable solar energy in urban areas. In the article, it is proposed to apply method for estimating the solar energy potential of at a specific geographic point, based on a combination of the calculation method for determining the solar radiation characteristics and actinometric measurements. Volzhsky of the Volgograd Region, like most settlements in the Lower Volga region, has a high solar energy potential: 1228.8 kWh / m² for the horizontal surface of the southern orientation of the receiving surface of power plants, which can be increased by 16.2% at its optimal orientation relative to the horizon and the sides of the world. However, the expansion of the utilization of the solar energy potential of the district may be limited to the location of the existing buildings and structures at which power plants may be located in urban development conditions

INDUSTRIAL CONSTRUCTION OF TATARSTAN: MAIN TRENDS
DescriptionThe article describes the main trends in industrial construction in the Republic of Tatarstan, as well as analyzed the costs of the Republic, its major projects for industrial construction. The result of construction, as a type of production activity, is construction products - finished or prepared for operation buildings or structures for production or non-production purposes. The construction ensures the creation of fixed assets and production capacities of the economy. And the result of investments in fixed capital is the construction of new facilities and upgrading of equipment, purchase of necessary vehicles and tools, i.e. investment in different sectors of the economy that will facilitate the acquisition, establishment, expansion of fixed assets of enterprises, and thus contribute to the development of economic entities and economy as a whole. The Republic takes leading positions in the ranking, not only in terms of housing, but also for industrial construction. The shortage of capital in the field of investment and construction activity and the weak development of the construction industry will not be able to implement large industrial and infrastructure projects. The article describes the main steps of the Republic, aimed at attracting investment and ensuring development of the construction industry, particularly industrial construction
