The purpose of the study is to analyze the current level of development of the digital infrastructure of the urban planning sector, to identify the features of information technology support for the implementation of the BIM concept at the stages of the life cycle of the CCS and the functionality presented on the national market of solutions that support BIM technology. Method. Within the framework of the study, the methods of logical, structural, comparative, system analysis were used; modeling and graphical presentation of results.Result. It has been established that in the current period, most companies in the Russian architecture and construction industry are considering the transition to a fully integrated BIM as a long-term development format. An objective obstacle to a quick transition is the complexity of complex IT support for BIM processes and the level of current development of digital infrastructure. It has been established that the priority direction for the development of the IT industry in the context of ensuring the implementation of the BIM concept is the formation of a single ecosystem of Russian BIM software. Along with the need to develop competitive Russian software products, ensuring their interoperability and standardization of data exchange formats are highlighted as the main problems. The key parameters for assigning a software product to the BIM group are determined, the levels of maturity of the BIM data exchange process are identified, and approaches to the organization of exchange processes are considered.Conclusion. The proposed criteria for classifying software products as solutions that support the BIM concept can be used in the formation of functional requirements for the developed import-independent software products. The interpretation of the interoperability reference model in relation to BIM technology can be used to develop the integration capabilities of BIM tools in a single information technology environment of general data, and also become a methodological basis for creating an open national data exchange standard.","PeriodicalId":202454,"journal":{"name":"Herald of Dagestan State Technical University.

The purpose of the study is to identify the main causes of the growing shortage of personnel resources of territorial divisions of internal affairs bodies (ATS) and appropriate methods of their elimination.Method. When searching for the causes of the personnel shortage of the ATS, the procedures of system analysis were used, on the basis of which the central problem of the staffing of the ATS was identified, a number of tasks and goals were formulated, for the solution of which additional material resources are not required. Mathematical methods of system dynamics were used to solve most problems.Result. In the work, based on the analysis of the operational situation, regulatory and methodological support of the management activities of the internal affairs bodies, it is concluded that there is a systemic problem: the dynamism of the management system of the internal affairs bodies is disrupted, as a result of which the effectiveness of the management process decreases, leading to an increasing trend of a shortage of ATS units. To solve the identified problems, the authors propose the following technologies: calculation of the profitability of the work of territorial divisions of the Ministry of Internal Affairs of Russia, which allows to assess the necessary and sufficient level of efficiency of the use of all types of resources in the performance of official tasks; development of a methodology for calculating the personnel needs of territorial divisions of the Ministry of Internal Affairs of Russia, taking into account the complexity of their activities, workload and regional characteristics; introduction of a new approach to assessing the activities of divisions The Ministry of Internal Affairs of Russia, based on the separation of the reporting system and the evaluation system, improving personnel policy in terms of making the service in the Department of Internal Affairs more attractive, taking into account the new values of modern society. For each presented task, its own tools and solution technology have been developed.Conclusion. The solution of the identified tasks will ensure the uniformity and \"feasibility\" of the workload of its employees, the transparency of the assessment of their activities, which will increase the motivation for conscientious work. Coupled with the improvement of personnel policy to make the service in the internal affairs bodies properly attractive, the expected synergetic effect will reduce the severity of the problem of personnel shortage.","PeriodicalId":202454,"journal":{"name":"Herald of Dagestan State Technical University.

Development of automated network attack detection systems capable of adapting to the ever-changing nature of network attacks and new types of threats. Such systems should be based on machine learning algorithms and models that are able to identify complex dependencies between data in the learning process.Method. To train the models, a sample with signs of normal and abnormal traffic was prepared, and it was thinned and balanced as a result of preliminary statistical analysis. Five machine learning algorithms were selected and tested, both on a training set of features and on a real test set obtained experimentally. Based on the results of the experiments, a random forest classifier was selected, which showed the best results.Result. A model for detecting network intrusions has been developed, which showed a detection accuracy of 0.99 on real traffic.Conclusion. It is shown that a machine learning-based network intrusion detection system can solve the problem of flexible protection that could adapt to the ever-changing nature of network attacks, since one of the most important advantages of machine learning in detecting network intrusions is the ability to learn the signs of attacks and identify cases that are uncharacteristic of those that were observed earlier.","PeriodicalId":202454,"journal":{"name":"Herald of Dagestan State Technical University.

The purpose of the study is to develop a methodology for assessing the security of an automated control system of critical information infrastructure from DDoS attacks. The purpose of the methodology development is to provide the decision–maker with a scientifically sound tool for assessing the risk of implementing a DDoS attack.Method. To achieve the stated goal of the study, simulation modeling based on the Monte Carlo method was used.Result. The expediency of using Monte Carlo simulation to assess the probability of server failure under DDoS attacks is confirmed. It was concluded that the server can be considered as a queuing system, however, the flow of incoming applications under DDoS attacks is not Poisson, so the use of analytical expressions to assess the probability of failure is considered incorrect. The simulation results allow the decision-maker to assess the probability of server failure and make organizational and technical decisions to increase the level of security. Analysis of the simulation results showed the effectiveness of improving server performance by increasing service channels.Conclusion. Thus, the developed methodology will be useful in conducting an information security audit of an organization to justify the amount of its insurance premium in the framework of cyber risk insurance.

The aim of the study is to study the methods of temperature control using the Peltier element in a given temperature range.Method.

A technique for controlling the Peltier element to maintain the required temperature is obtained, which is carried out using the PWM method generated by the ATmega2560 processor. The H-bridge on the L6203 integrated circuit switches the current direction and can control the current up to 5A on the Peltier element using a PWM signal.Conclusion. The resulting control algorithm provides an increase in the heating current on the Peltier until the temperature rises to a predetermined high temperature value, and then by changing the direction of the current, a cooling current is created on the Peltier element until the temperature of the copper plate drops to a predetermined low temperature. With repeated repetition of this sequence, the regularity of temperature changes is monitored to study the process of heating and cooling the plate using the Peltier element.","PeriodicalId":202454,"journal":{"name":"Herald of Dagestan State Technical University.
