Blockchain Technology to Manage the Energy Supply of Real Estate
In the framework of creating a digital ecosystem of
commercial real estate objects, the main problem is the
formation of a digital environment for managing all
components of engineering systems that ensure the vital
activity of the real estate object.
The aim of this work is to develop a system for accounting
for mutual settlements for electricity consumed on the basis of
a distributed ledger using blockchain technology. To assess the
effectiveness of the system a simulation model was built using
AnyLogic system. Based on the model the system architecture
was designed and a software application of the distributed
ledger was developed.
In universities and technical colleges with relevant IT qualifications in one semester multiple streams, courses and specializations can use software products for training purposes. IT services of universities should deal with the challenge of creating the infrastructure of educational applications that can support the educational process. We note that the number of specializations which study information technology are growing every year (for example, in HSE there are disciplines-minors, which can enroll students coming from any field). Also in the recent years, online courses have started to become popular. If the load is not planned ahead taking into account future trends, the power of even the most high-tech infrastructure will be insufficient. Calculation of the corresponding load on the infrastructure must be made in the planning process of the disciplines, so that we can reserve appropriate facilities, and thus organize an effective learning process.
Software developers use a variety of benchmarking tools that are complex and do not provide the necessary information for the participants of educational process planning.
This article discusses the construction of a simulation model that supports the educational process planning. The simulation is carried out using the capabilities of the tool AnyLogic 7. The aim of this work is to develop a simulation model designed to estimate the load on the information system used in the educational process. In addition, besides the description of the model, the article presents the results of calculations used for various options of the information system (private cloud or on a server at the university). The simulation results were confirmed by data obtained during practical classes at the university. This model gives us the opportunity to plan the educational process in order to achieve uniformity of the load on the services. If necessary, the model allows us to make a decision about the location of the educational information system: on servers of the university or in a private cloud.
Developing variants of scenarios for a production enterprise’s achieving a desirable fi nancial position using simulation modeling tools requires a specifi cation and verifi cation of requirements for the simulation model. Availability of such variants of scenarios allows stakeholders to select the most effi cient solution. The verifi cation is performed by business analysts and key stakeholders; the aim is to assess readiness of the requirements for fi nal approval and to check that the requirements provide all material information for future work. Verifi cation includes evaluating the requirements regarding their compliance with the company’s business analysis standards, as well as assessment of the model’s completeness and common terminology used for description of the requirements. Understanding the desired solution, which meets all the stakeholders’ requirements, is the most important element in requirements verifi cation. For developing a simulation model, which is essential for determining variants of development scenarios and covers fi nancial fl ows of a typical production company, a list of verifi ed requirements is determined. Criteria of requirements verifi cation include not only acceptance criteria, but also the Graphical Requirements Analysis framework (GRA framework), that is used for verifi cation of functional requirements. The verifi ed requirements should be used at diff erent stages of constructing the simulation model, which is focused on development of scenarios for achieving the production enterprise’s desired future fi nancial position. Modeling scenarios of future development of the types “what will happen, if…?” and “what to do to achieve the goal?”, using simulation modeling systems allows one to dramatically increase the quality of decision making.
2020 43rd International Conference on Telecommunications and Signal Processing (TSP), IEEE Conference Record #49548, which is held during July 7-9, 2020, in Milan, Italy (virtual event), we would like to welcome you in this event and thank you for your personal support and for your papers, which are published in the proceeding. In this respect, we would congratulate you for your success since every paper has been carefully reviewed by at least two international referees. In cooperation with the Technical Co-Sponsors, IEEE Region 8 (Europe, Middle East and Africa), IEEE Italy Section, Italy Section SP Chapter, Italy Section VT/COM Joint Chapter, IEEE Czechoslovakia Section, IEEE Czechoslovakia Section SP/CAS/COM Joint Chapter, Scientific Association for Infocommunications, a Sister Society of the IEEE and the IEEE Communications Society, Media Partners, Applied Sciences, Remote Sensing, and Sensors - open access journals by MDPI, International Journal of Advances in Telecommunications, Electrotechnics, Signals and Systems (IJATES2 ), the TSP 2020 is organized by eighteen universities from Czech Republic, Hungary, Turkey, Croatia, Taiwan, Japan, Slovak Republic, Spain, Bulgaria, France, Romania, Slovenia, Greece, and Poland, for academics, researchers, and developers and it serves as a premier annual international forum to promote the exchange of the latest advances in telecommunication technology and signal processing. The aim of the conference is to bring together novice and experienced scientists, developers, and specialists, to meet new colleagues, collect new ideas, and establish new cooperation between research groups from universities, research centers, and private sectors. The TSP Conference goes back to 1977, when it was the first time initially organized by enthusiasts from the Department of Telecommunications of Brno University of Technology as a national meeting held in Brno. Because of the success of the first event it was also repeated in 1978 and this annual repetition of the conference became a tradition. In the 1980s, TSP was transformed into an international conference and was opened also to participants from around the word. In the 1990s, during the years of economic transformation in the Czech Republic, TSP extended its base of supporters also by commercial entities active in different fields of telecommunications. In 2008, in cooperation with BME Hungary, the TSP Conference was first time organized abroad. To extend the cooperation between European Universities, in 2011 the organizing committee was joined by other six universities i.e. CTU Czech Republic, KTU Turkey, STU Slovak Republic, UL Slovenia, VSB Czech Republic, ZUT Poland, which was since 2015 extended worldwide by Seikei University in Japan, TU-Sofia Bulgaria, University of Osijek in Croatia, Isik University Turkey, ITU Turkey, NTUST Taiwan, Tecnocampus Spain, and Université Paris 8 in France, etc. During the 43rd edition of TSP we are grateful for their contributions and support.
The article is devoted to the problem of development and application of information technologies in the strategic management of industrial enterprises under uncertainty based on mathematical modeling. The purpose of the article is to develop tools that support decision-making when choosing strategic guidelines for the development of enterprises using economic and mathematical methods. The study of the system of strategic management of industrial enterprises, which has the property of development, based on the application of the methodology of system analysis. A model of the strategic management process in the form of a logical structure containing a combined decisionmaking procedure for solving problems, ranging from the study of the environment and the development of the mission, and ending with the creation of economic and mathematical tools and its use to evaluate decisions. The economic and mathematical tools to support decision-making on the strategic guidelines for the development of industrial enterprises in the conditions of stochastic uncertainty.

The review discusses the political-economic aspects of the concept of distributed capitalism allowed for by blockchain technology. As opposed to the first era of the Internet, where the industry of financial and information services was dominated by intermediaries, the blockchain era is characterized by development of a new institution of trust; disruption of financial intermediation; economic inclusion of hundreds of millions of citizens in developing countries; an increase in competition and a decrease in inequality. The paper focuses on the content of key political-economic categories being redefined in the blockchain era. First, labor value gives way to creative value which is manifesting itself in cryptocurrencies. Second, exploitation of workers is replaced by digital discrimination. The blockchain revolution is a solution to the problem of discrimination against intellectual property creators, who have to hand over a large part of the value created to intermediaries. Third, capitalism characterized by information monopoly gives place to free competition based on rivalry between cryptocurrencies. Fourth, class struggle is substituted by confrontation between agents of information monopoly system and those of distributed economy. The author considers the main opposition to distributed capitalism to stem from the feudal financial system which loses ground under new conditions, where economic agents may use alternative currencies and interact directly with one other without risk and high transaction costs.
In the paper simulation models of some common types of traffic accidents are proposed. Automobile-pedestrian accident on unregulated crosswalks with one or two lanes. Statistical modeling the probability of these road accidents occurrences was implemented.
