The advantages of paperless trade and the need to implement the main provisions of National Strategy for Sustainable Socio-Economic Development of the Republic of Belarus are indicated. The author proposes the ways of development of the export potential of the Republic of Belarus witch based on an analysis of the processes of digital transformation of Belarusian trade.

To develop innovative activities, the state offers various options for assistance and support within the framework of the innovation stimulation system. However, many of the proposed support tools remain unclaimed, since it is often difficult for organizations to evaluate and calculate the effect of their use due to the insufficient development of information systems. The level of automation of accounting is insufficient for making quick and informed decisions, which reduces the competitiveness of organizations. The main drawback of the existing systems of automation of accounting and  management in industrial organizations is their fragmentation, inflexibility, and inconsistency with modern requirements for complex information systems. Many organizations keep records in separate workstations, the so-called workstations, many calculations are carried out by means of table editors; the transition to integrated information systems has not yet become widespread. The starting point in the financial mechanism for stimulating innovation should be tools to stimulate the automation of business processes. The limiting factor for the transition to such systems is the high cost of implementation, therefore, the article considers the advantages and disadvantages of applying soft loans in order to stimulate further innovative development in this area, and also suggests expanding the practice of using such a promising tool to stimulate investment in business informatization as innovative vouchers on information technology. The advantages of such an instrument include the strengthening of the link between research, educational institutions and the real sector of the economy, and this tool also has such advantages as high transparency of spending and targeting. The relevance of the chosen research topic is also due to the fact that, according to the Concept of the National Strategy for Sustainable Development of the Republic of Belarus for the period until 2035, digitalization based on high technologies and new business models has been identified as a key element of the new model of the national economy [1].

The work is devoted to the problem of EAEU’s digital transport corridors ecosystem creating. The purpose of this article is to develop approaches to the organizational and functional structure forming of the digital transport corridors ecosystem and to identify the priorities for creating and saturating with services a National electronic transport and logistics system. The factors and conditions for the development of the international digital transport corridors and the basic developing principles of the organizational and functional scheme of their ecosystem are determined. The organizational and functional structure of the digital transport corridors ecosystem is proposed, the ecosystem's levels are described, the upper-level objectives of the ecosystem organization are determined. The author’s approach to the organization of national platform solutions in the field of transport is substantiated. Unlike the existing ones, it envisages the creation of a “Cluster” of digital platforms, both at the national and supranational levels of the ecosystem, ensuring a “seamless” integration of instrumental, infrastructure and applied digital platforms. Methodological issues of the digital platforms functionality designing for cooperation and coordination of the transportation process participants as well as state regulation have been solved. In the work, general scientific methods were used to cognize economic phenomena and processes (analysis and synthesis, a systematic approach, the dialectical method, methods of composition and decomposition of data, etc.). The main study results were systemic approaches to the organizational and functional structure formation of the digital transport corridors ecosystem, the methodology of the digital platform functionality designing and the methodology of developing services of the electronic logistics digital platform based on a map of the speed of development, significance and level of investment. The solutions to the problems of unification and interoperability of digital platforms are outlined. The using area of the proposed solutions: further creation of the National Electronic Transport and Logistics System in the Republic of Belarus, taking into account the development of the EAEU's digital transport corridors ecosystem.

The article considered the theoretical and practical examples of the Republic of Belarus on the development ofcompetition, the role of competition in the life of society is indicated. Definitions of the term «competition» are given. A brief description of the types of market structures is given: perfect competition, monopolistic competition, oligopoly, monopoly. The mechanism of development of competition in the Republic of Belarus at the present stage is considered, including through the creation of an antimonopoly structure, ifs goals, objectives, ongoing efforts to develop competition, adjust the regulatory framework, international experience, etc. The directions that promote competition have been identified: improving legislation, expanding the powers of the antimonopoly structure, further developing preventive institutions of antimonopoly regulation, advocating competition, developing exchange trading, etc. The development of competition is a tool to achieve the goals of social-economic development of the country.

In this paper, the task of assessment of numerical conditioning of multilayer perceptron, forecasting time series with sliding window method, has been considered. Performance of the forecasting perceptron with various hyperparameters sets, with different amount of neurons and various activation functions in particular, has been considered. Main factors, influencing on the neural net conditioning, have been revealed, as well as performance features, when using various activation functions. Formulas for assessment of condition numbers of individual components of the forecasting perceptron and of the neural network itself have been proposed. Comparative analysis of results of training the forecasting perceptron with various hyperparameters on modeled time series has been performed. Conditions, providing the best stability and conditioning for the neural network, have been formulated.

The article discusses current issues of virtualization of the network infrastructure of educational institutions. The analysis of the literature on this issue. A new approach to creating a cloud virtualization environment for the educational institution’s network infrastructure is proposed, which is based on the joint use of virtualization technologies and software-defined networks. This approach allows you to unify the process of creating a network infrastructure, scale the resources provided on demand with minimal organizational and technical costs. The data processing center of the Belarusian State University has implemented a model that includes virtual network segments. Using virtualization technologies and software-defined networks allows you to unify the process of creating network infrastructure, scale the resources provided on demand with minimal organizational and technical costs, adapt the virtual infrastructure to the requirements of a particular educational institution.

Significant advances in the implementation of information technology in the educational process cannot occur on their own. Success in this area is ensured by many years of hard work aimed at a gradual transition from the use of traditional teaching methods to automated ones. This transition on the example of implementing a computeraided design of technological processes is considered. The stages of the formation of this activity are described, starting with systems based on SM EVM (СМ ЭВМ, abbreviation of Система Малых ЭВМ – literally System of Mini Computers. It was the general name for several types of Soviet minicomputers produced in the 1970s and 1980s) operating under the control of a real-time operating system, and ending with electronic complexes for information support of design and technological design based on PDM systems.
