GENERAL ISSUES OF FORMALIZATION IN THE DESIGNING: ONTOLOGICAL ASPECTS

An ontological model of the dual nature of safety in technical systems
Lobach D.
Аннотация

The aim of this study is to structure the aspects of control and safety in technical systems using the concepts of entropy, negentropy, and information, in order to identify additional factors for assessing controllability and loss of control in the process of decision-making or the loss of emergence. The article examines specific properties of ergatic systems that contribute to forming the informational basis for describing the structure, control, and safety levels of technical systems. A two-level ontological framework is proposed for evaluating the controllability of a technical system through the analysis of its informational characteristics. Negentropy is interpreted as an indicator of the system’s condition, reflecting the combined effect of internal properties and external influences on its functionality. The configuration and number of safety subsystems define the upper limits of controllability and safety within a technical system, including in scenarios involving emergence. The dualism of safety lies in capturing both the negentropy (describing the state of order in the system, as well as its actual — or worst-case — levels and structure of control and safety) and the information about the state of control and safety (expressed through the required number and configuration of safety subsystems needed to achieve optimal performance). The article compares several concepts and regularities from information theory and thermodynamics for their applicability within the ontological framework of safety dualism. The analysis of safety dualism enables the comparison of structural and control architectures in technical system designs, the identification of factors contributing to successful or failed control, the definition of conditions under which emergence is lost, expert assessment of communication and control systems, and the development of optimal control and safety regimes—taking into account both resource depletion and the need for resource replenishment.

Formalization of indicator requirements in multidimensional evaluation of objects
Mikoni S.
Аннотация

The development of a multidimensional evaluation model for an object involves meeting specific requirements for each assessed indicator. The complexity of this process is proportional to the number of indicators. The requirements for an indicator are divided into quantitative and qualitative ones. Quantitative requirements are formalized as a set of logical constraints on indicators values. These constraints are modeled using first-order predicate logic. Qualitative requirements account for the decision maker’s inclination or disinclination toward risk in tasks involving the selection of a preferred option and in axiomatic classification problems. When information about risk preferences is unavailable, and the boundaries between adjacent classes are vague, qualitative requirements are modeled using monotonic or non-monotonic linear and piecewise-linear functions defined over the indicator’s scale. The propensity to take risks is represented by a value or utility function that changes slowly at the lower end of the scale and more rapidly toward the upper end. Conversely, risk aversion is modeled by a function with the opposite behavior. To reflect the fuzziness of class boundaries, evaluation functions with varying rates of transition across class borders are employed. The paper proposes a minimum set of features that distinguish all possible approaches to modeling both quantitative and qualitative requirements for indicator values. The sets of features for solving the problems of ordering and classifying objects differ only quantitatively due to the need to specify requirements for each class. This information is entered into the "Features / Indicators" table of the spreadsheet processor; once imported into the system, an assessment model for each indicator is automatically generated based on the specified requirements.

APPLIED ONTOLOGY OF DESIGNING

Detection of anomalous cryptocurrency transactions using neural networks and ontologies
Kotenko I., Levshun D., Zhernova K., Chechulin A.
Аннотация

The article explores an effective approach to detecting anomalies in cryptocurrency transactions using neural network models, including convolutional, deep, and gated recurrent units (GRUs), and compares their performance with other existing methods for identifying illicit transactions in cryptocurrency networks. A research of relevant studies is conducted in the fields of transaction data analysis in the cryptocurrency network, data visualization for transaction analysis, and the use of computer vision techniques for detecting anomalous behavior. The subject area of the study is defined. The problem of detecting anomalies in cryptocurrency transactions is based on the fact that these transactions are pseudonymous, i.e. there are no direct indications of the identity of the sender and recipient. The relevance and contribution of this work lie in the development of a method capable of identifying anomalous transactions with high accuracy in near real-time. Experimental studies were conducted using a dataset of cryptocurrency transactions, applying both neural and non-neural classifiers. The results are compared against existing approaches in the field. The experiments demonstrated that gated recurrent units outperformed other neural models in this task, achieving an accuracy of 0.94, precision of 0.95, recall of 0.93, and F1-score of 0.94, indicating the high effectiveness of the proposed model. Nonetheless, this approach showed slightly lower performance compared to traditional machine learning algorithms, such as optimized distributed gradient boosting. The novelty of the proposed approach lies in its use of statistical characteristics derived from the transaction graph, combined with deep learning and gradient boosting techniques. The approach can be applied in the development of software tools for detecting illicit cryptocurrency transactions within information security systems and digital forensics.

Application of machine learning methods in designing combustion chambers of gas turbine engines
Borisov D., Simovin K., Yukina D., Blagov A., Chechet I., Matveev S.
Аннотация

The article considers the application of a recurrent neural network with long short-term memory (LSTM) and a gradient boosting algorithm for determining the key geometric dimensions of the diffuser of the combustion chamber of an aircraft gas turbine engine. Numerical modeling of physical processes in the diffuser is performed based on the finite element method, and total pressure losses are subsequently calculated. A database is compiled containing various geometric configurations of the diffuser model alongside the corresponding total pressure loss values. The configuration with the lowest total pressure loss is selected as the reference. The performance of the gradient boosting method is compared with that of the LSTM neural network, based on the total pressure loss data obtained from numerical modeling of the diffuser across a range of geometric configurations. The gradient boosting approach yielded an error of 1.64%, whereas the LSTM network demonstrated an error of 7.28%.This approach enables the creation of a design database for diffuser configurations, facilitates the use of simulation data to train neural networks, and allows for subsequent training on alternative designs. The results can be applied in the design and optimization of combustion chambers in aircraft engines.

Development of the information support system for a territorial administration body
Maksimov M., Volkova V.
Аннотация

The article examines the development of the information support system of the territorial administrative body. To date, there is a notable lack of published research focused on the specific features of information support for administrative bodies, especially for the level of city districts. The concepts of a multi-level information and control complex and a service-oriented architecture have been adapted to the context of information support for administrative management in a city district. To substantiate the selection of innovative technologies and services in the development of such systems, the article proposes methods and models grounded in a system-targeted approach. The goals and objectives of territorial administration have been systematically structured and analyzed. The article presents models for organizing expert evaluations based on assessing the impact of innovative technologies and software products on the achievement of administrative goals and objectives, while also considering their interaction with the existing information infrastructure. The proposed methods and models enable the evaluation of the relevance and effectiveness of innovative technologies in supporting the key functions of the information and control complex for administrative management at the city district level.

Digital transformation of industrial facility processes of oil and gas field
Tereshko Е., Malashenko M., Seredin Е.
Аннотация

The article explores the impact of digital transformation on the processes associated with industrial facilities in the oil and gas sector, with the aim of enhancing their efficiency. The object of the study is the economic entities involved in the operation of an oil and gas field, while the focus is on the integration of advanced digital technologies — such as the Internet of Things, building information modeling (BIM), additive manufacturing, robotics, and artificial intelligence —across the entire life cycle of industrial facilities. The application of digital tools is examined at various life cycle stages, from conceptual design through facility commissioning to decommissioning. The article outlines the stages of the field development life cycle — "Design," "Field Development," and "Decommissioning"— and provides a detailed breakdown of the "Design" and "Field Development" phases. A matrix linking digital technologies to specific life cycle stages of oil and gas field development has been formed, serving as the foundation for constructing an ontology of facility development. Based on this framework, the authors propose recommendations to support the digital transformation of economic entities involved in oil and gas field development, presented in the form of a strategic roadmap.

A method for mining frequent patterns considering feature hierarchies
Zuenko А.
Аннотация

This article advances the author’s approach to solving data mining problems by integrating methods from explainable artificial intelligence and constraint programming theory. It proposes a method for mining frequent closed patterns that accounts for feature hierarchies. The approach is based on the construction a binary search tree and eliminates the need for a preliminary candidate generation stage. Feature hierarchy constraints are handled through specialized procedures that reduce the search space, thereby mitigating the effects of combinatorial explosion. In contrast to commonly used algorithms, the proposed method employs a depth-first rather than a breadth-first search tree traversal strategy. Its core component is a logical inference procedure that computes the closure of a given feature set. The method also supports the incorporation of additional constraints to further reduce the search space. Compared to existing approaches based on logical inference, it avoids redundant computations when determining closures across feature sets.

METHODS AND TECHNOLOGIES OF DECISION MAKING

Fuzzy time series granulation methods for data analysis
Burnashev R., Sergeev Y., Nazipova A.
Аннотация

The growing dimensionality of data, driven by the multitude of heterogeneous time series, requires the development of efficient methods for their processing and compression. This article presents an approach to data compression where the data are represented as time series, using granulation with fuzzy logic methods. The study analyzes average daily temperature data in the Republic of Tatarstan collected from 1881 to 2024. Data granulation enabled a significant compression of the data volume. Fuzzy summarization was applied to transform the original numerical data into information granules, facilitating the automatic generation of granular descriptions of time series behavioral patterns. The summarization of time series states was carried out using fuzzy logic methods, including a rule set, membership functions for each season, interval-based linguistic variables, and a defuzzification software module. The implementation of the proposed approach demonstrated a reduction in data volume from 52,534 to 7,504 points, achieving a compression ratio of approximately 85%. The developed methods are applicable for analyzing large datasets across various domains.

Multi-agent method to improving adaptive real-time management of computing resources
Kiriakov F., Skobelev P.
Аннотация

The paper presents the development of a multi-agent method aimed at meeting the growing demand for computing resources by enhancing the adaptability and efficiency of real-time management. In practical scenarios, it is essential to enable prompt and flexible adaptive adjustments to the task execution schedule in order to improve overall resource utilization. The proposed multi-agent resource management method is based on a previously developed "network of needs and capabilities" model, which enables smooth, adaptive modifications to the execution schedule. This process involves a sequence of atomic stepwise changes to the resource allocation plan, including local task shifts within a single computing resource, as well as the displacement and redistribution of tasks across multiple resources. Each task agent calculates an optimal “patch” to maximize the global efficiency of the system, accounting for the satisfaction functions of all tasks affected by the change. A key innovation is the introduction of a collective decision-making mechanism based on the computation and coordination of these patches. This allows for dynamic optimization of the schedule without requiring full rescheduling or transitioning to a fully decentralized solution, which would eliminate the shared data environment of the agent system. Experimental results demonstrate that the proposed method increases system efficiency by 25–30% compared to non-adaptive control approaches, which lack the ability to selectively revise agent interactions or reallocate tasks among resources. The method also enhances the scalability and fault tolerance of the system, expanding its applicability to a broad range of dynamic resource allocation problems in computing, manufacturing, and logistics.

Intelligent support for the analysis of urban development projectsbased on ontology
Shcherbakov А., Sadovnikova N., Parygin D., Rashevskiy N., Gurtyakov A.
Аннотация

The design of urban development projects relies on approaches that involve the creation of new methods for knowledge extraction and representation. These approaches enable the adaptation of digital models to changing conditions and facilitate the coordination of interdisciplinary requirements. This article addresses the formalization of knowledge related to building structure types, regulatory standards, operational conditions, and other data that must be considered in urban development processes. Based on an analysis of design workflows and regulatory and reference documentation, an ontology has been developed to support the evaluation of urban development projects. The article proposes a method for analyzing such projects that integrates data from informational, geometric, and ontological models to verify the compliance of digital models and design documentation with relevant norms and standards. The method is applicable across a wide range of urban development projects; its use depends on the completeness of the databases and rule sets involved. The software implementation of the proposed method reduces the labor intensity of project review and contributes to improving the overall quality of urban development outcomes.

Digital models of damaged rod systems for intelligent support throughout the life cycle
Doronin S., Filippova Y.
Аннотация

The article explores an approach to intelligent support for the life cycle of damaged rod systems, focusing on information support for decision-making in poorly structured operational scenarios. Such situations are marked by the need to justify technical solutions within limited timeframes and in the absence of reliable data on the stress state and residual load-bearing capacity of the damaged structure. The proposed information support involves obtaining a priori data on the structural condition under hypothetical failures of individual elements. This is achieved by constructing digital models that represent the stress state of the damaged system. For a typical poorly structured situation, the specific content of the decision-making tasks is identified, with each task linked to a set of key questions that must be answered. These questions in turn define the requirements for the digital models of damaged rod systems. Uncertainty in such weakly structured scenarios is addressed through a stepwise process: “situation assessment → analysis of decision-making content → formulation of key questions and definition of requirements for digital models → multivariate computational modeling and creation of digital models for decision support.” The development of digital models is carried out in advance of system operation and involves computational simulation of the failure of individual structural elements, followed by analysis of their impact on the system's overall stress state. The novelty of the approach lies in establishing a clear correspondence between the tasks of assessing the safe operability of damaged rod structures and the technologies used to simulate the failure of their components.
