INTELLIGENT INFORMATION SYSTEMS FOR SOLVING PROBLEMS OF TERRITORIES INTEGRATED DEVELOPMENT: APPROACHES AND SOLUTIONS REVIEW
Annotation: The article provides a review of various approaches to defining integrated territorial development and classification of the effects of their use. The experience of using intelligent information systems as the main tool for planning and implementing integrated territorial development projects is analyzed. The practices of using intelligent information systems, including geographic information and expert systems, and decision support systems are considered. An analysis of practices and trends in the use of artificial intelligence to solve integrated territorial development problems was carried out. Evaluation of the socio-economic efficiency of integrated urban development activities is an important stage in project planning and implementation. This allows us to determine how useful and beneficial these activities will be for the city and its residents. The evaluation methods used have a number of shortcomings related to the insufficient completeness and reliability of the initial information, as well as insufficient consideration of mutual cause-and-effect relationships. The use of special methods allows for a more objective and high-quality assessment of the development of the territory, as well as an assessment of the effectiveness of investments and decisions made. This is important for both government agencies and business structures that participate in the development of the territory. Intelligent information systems play an important role in the development of cities and territories, providing opportunities for analysis, forecasting and decision making based on various data and methods. When analyzing data, the relationships and dependencies between various factors of territorial development are taken into account, as well as probabilities and risks. A comparative analysis of intelligent information systems used in the world was carried out. Each of these systems has its own characteristics and capabilities, which may be important when planning the integrated development of territories depending on the tasks set. But there are currently no systems that would completely cover the management and economic processes in urban development. Their advantages and disadvantages are considered. In conclusion the prospects for using intelligent information systems for making management decisions that ensure the integrated development of territories.

METHODS OF DATA ACQUISITION AND PROCESSING FOR CONSTRUCTING EARLY DIAGNOSTICS ALGORITHMS OF AIRCRAFT ELECTROMECHANICAL SYSTEMS
Annotation: Modern and future aircraft are characterized by an increased degree of electrification of onboard systems and the use of electromechanical systems to ensure critical functions of the aircraft flight control system. Widespread implementation of onboard electromechanical systems requires their safe and efficient operation, for which purpose it is assumed that the aircraft is equipped with an early diagnostics system for faults. Electromechanical systems of an aircraft, the closed control loop of which is implemented based on feedback signals for the speed or movement of the output link, are subject to high requirements for the quality of regulation, including under the action of mechanical load. Deterioration of the characteristics of an electromechanical system is associated with degradation processes that develop in individual components and can be determined based on data obtained both in the passive mode during a typical flight and in the active mode when processing specified control signals between flights in ground conditions. Modern artificial intelligence methods allow their effective use in creating algorithms for early diagnostics of electromechanical systems for classification and forecasting of technical condition using big data containing valuable information about work processes associated with the development of faults. To obtain such data, the main scenarios of operation of electromechanical systems were studied in the work, allowing to obtain representative samples. To ensure an automated data collection process using signals transmitted via standard interfaces of information interaction of the integrated control system with end devices, as well as from additionally used sensors, data accumulation methods were developed and studied using the results of modeling, testing and operation. Based on the obtained data, it is possible to assess the degradation of static and dynamic characteristics of electromechanical systems and determine their significance in classifying the technical condition for localizing malfunctions and performing condition-based maintenance. For this purpose, methods for processing the obtained data were developed and studied and the practical application of the results for subsequent on-board integration of the diagnostic system was assessed.

APPLICATION OF STANDARD PERSONAL COMPUTER INTERFACES FOR INTEGRATION OF COMPUTING DEVICES IN SOFTWARE&HARDWARE COMPLEXES
Annotation: The article discusses the design of software and hardware systems based on personal computers using locally connected hardware accelerators based on graphics processors (GPUs) or programmable logic integrated circuits (FPGAs) with FPGA or APSOC architecture. Since the set of peripheral devices included in a personal computer is limited, it determines the achievable data transfer rate. Thus, the computing performance of hardware accelerators added to the complex must be consistent with the technically achievable speed of transmitting input data to the accelerator and returning the calculated values. Interfacing with a personal computer also requires the presence of a corresponding interface controller in the connected accelerator. Options for connecting FPGA-based accelerators to a personal computer using the PCI Express interface to form a software and hardware complex designed for tasks such as digital signal processing, information security and regular expression recognition, implemented on the basis of an accelerator with parallel architecture, are considered.

PROPOSALS FOR A STANDARD DESCRIBING THE ARCHITECTURE AND DATA FORMAT OF SMART STANDARDS
Annotation: Nowadays work is underway on a series of preprinted national standards that should prepare the normative and formalized field for the implementation of SMART standards. With the intensive development of this area of domestic standardization, a number of proposals arise related to the approaches on which the authors of this series of preprinted national standards rely. The article makes some suggestions, based on the best practices of modern software engineering, to improve the overall level of the field under consideration. During the development process, it is necessary to pay special attention to such aspects as the development of a typing system over the space of standardization objects, as well as the organization of a system of connections between similar objects. In addition, it is also important to dwell on the division of levels of abstraction and responsibility between each of the levels of the model structure of such documents. In addition, the article is based on the results of the review of the revision of the "Smart (SMART) standards. Architecture and data formats" from January 2024 and relies on the well-known experience of implementing and researching requirement-oriented formats, namely their focus on the degree of expressiveness of the requirements themselves. At the time of publication, this preprinted national standard has been revised based on the results of public discussion.
