GENERAL ISSUES OF FORMALIZATION IN THE DESIGNING: ONTOLOGICAL ASPECTS AND COGNITIVE MODELING
Modeling deviations of object quality indicators from the norm
Resumo
The concept of a norm on the scale of an object's quality indicator in the context of determining the most preferable object or its state is explored. The notions of permissible and maximum permissible deviations from the norm are utilized, with maximum permissible deviations defining the boundaries of the indicator scale. The fundamental version of the norm is represented as a segment on the indicator scale that excludes these boundaries. Point and semi-interval norms (“no more”, “no less”) are considered special cases of the interval norm, where the semi-interval norm reflects the alignment of the original interval norm's boundary with the indicator scale's boundary. For certain indicators, deviation in one direction from the norm is not only acceptable but also beneficial. An indicator satisfying this condition is termed optimized, while an indicator with undesirable deviations from both ends of the norm is termed neutral. In the model of belonging to the norm, three classes are distinguished: “norm”, “no more” and “no less” than the norm. Piecewise linear and nonlinear membership functions for these classes are proposed. In the nonlinear model, the boundaries of the interval norm are expanded to acceptable limits, leading to the intersection of membership functions of adjacent classes. Classification into these three classes is conducted separately for neutral and optimized indicators. Interpreting deviations from the norm, both unacceptable and acceptable, necessitates introducing two fictitious classes: “worse than the norm” and “better than the norm.” These classes are formed from the “not less than” and “not more than” classes. To calculate the membership function for each class across all indicators, a weighted average function is employed. Aggregated indices of belonging to the classes “norm,” “better than norm,” and “worse than norm” across all indicators are referred to as indices of stability, development, and deterioration of an object, respectively. These indices are used for a comprehensive assessment of the object, termed an indicator of its condition. An example of analyzing deviations from the norm, implemented in the modified SVIR-M selection and ranking system, is provided.

Cognitive modeling of adaptive learning processes
Resumo
An approach to modeling adaptive learning processes using signed and weighted directed graphs (digraphs) is examined. The vertices of the digraphs represent the characteristics of educational activities. The orientation, signs, and weights of the digraph arcs define the mutual influence of these characteristics. The dynamics of adaptive learning are modeled within digraphs using a specific impulse process algorithm. An external disturbance is introduced into a particular vertex of the digraph, and the propagation of this impulse is analyzed, enabling the prediction of values at other vertices of the digraph. The problem of optimizing the weights of digraph arcs is formulated, and an algorithm for solving it is proposed to achieve stability in the impulse process. Computational experiments on a digraph revealed that the objective function for optimizing the arcs of a weighted digraph is multiextremal. The occurrence of a local minimum is determined by the initial values of the vector of design variables (weights of digraph arcs) and constraints on these variables. Consequently, the qualifications of the developer of the adaptive learning model who assigns these values are crucial. Cognitive models of adaptive learning can be classified as prescriptive and descriptive. Prescriptive models outline what the adaptive learning process should be, while descriptive models depict existing adaptive learning processes and can be utilized to study their effectiveness. The developed methodology for cognitive modeling of adaptive learning processes allows for the prediction of learning outcomes and can be employed in the research, design, and implementation of adaptation mechanisms and intelligent control in e-learning systems, as well as in the didactic training of teachers in the field of e-learning.

Ontology of institutional design of modern social movements
Resumo
The article offers an ontological conceptualization of the institutional design of social movements and outlines its functioning mechanism in modern society. The purpose of the article is to identify the specifics of the institutional design of contemporary social movements. Institutional design is described as an integrated unity of virtual and real practices, incorporating a technological component. The core of this design is the project activity of social movement participants, and the construction of the reality through their participation in social and political life in both online and offline spaces. An ecosystem of design is presented, which includes a structure of opportunities and conditions for the creation, functioning, and institutionalization of social movements. Within this ecosystem, participants interact with an institutional environment that contains rules and regulations, as well as opportunities for participation in socio-political life. In a digital society, social movement participants have tools to create new algorithms for constructing reality using mobile applications and social networks. The ecosystem of institutional design expands as social movements gain political opportunities and organize both offline and online interactions with government authorities to address social issues.

APPLIED ONTOLOGIES OF DESIGNING
Ontological approach to managing adaptive training for specialist groups
Resumo
An integrated approach to solving the problems of managing the adaptive training process for groups of specialists is proposed, allowing for the consideration of changing external and internal factors, as well as the dynamics of changes in the specialists' training levels. This approach enables rapid adjustment of the training scenario to current situations. The implementation is based on ontological and predictive modeling of the adaptive training process. The article describes the meta-ontology for adaptive training of specialist groups in organizational and technical systems for automated training process management. It discusses an approach to solving problems of collecting, summarizing, and analyzing the cycle of intelligent management of adaptive training for specialist groups using meta-ontology. The developed meta-ontology enables automatic determination of trainees' knowledge and skills, stored in their profiles and updated based on completed training stages. This increases the efficiency of forming control actions (educational and training tasks) and improves the quality of training.

Design of an intelligent fire protection system
Resumo
Fire protection systems utilize detectors that process signals from fire sensors using threshold-based methods and generate a fire signal based on a logical function. Artificial neural networks can enhance these detectors by processing information from a network of sensors after being trained. To train these neural networks, extensive data sets are necessary, which can be obtained through fire simulations on a supercomputer. Field tests are costly, subject to random factors, limited to one or two rooms, and do not provide a comprehensive picture of fire development. Thus, designing intelligent fire systems falls under model-based design. Through modeling, large data sets were generated for training fire system algorithms, expanding the range of tasks they can address. A group of neural networks is proposed for optimizing the placement of multi-parameter sensors, identifying the type of burning material, detecting fires at early stages, and localizing the fire zone to select appropriate extinguishing agents. Artificial neural networks enable the prediction of fire development, mapping hazardous factors' distribution to find optimal evacuation routes. An example of model-based design for a ship fire protection system is provided.

Building an ontology to systematize the characteristics of the Internet of Things network
Resumo
A formalization of the Internet of Things network model designed for monitoring technological premises with telecommunications equipment at the Federal Research Center "Krasnoyarsk Scientific Center SB RAS" is presented. The network includes measuring devices, a telecommunications environment, data collection servers, and application software. For information interaction, a “publisher-subscriber” scheme and a lightweight protocol with a low load on communication channels are used. An ontology has been created that describes the network architecture and the properties of devices that collect, transmit, store, and process data. The ontology contains classes representing the concepts of the subject area, relationships, data properties, ranges of their changes, and critical values that limit the attributes of ontology elements. Ontology objects have their own digital representation in databases, including measurement results obtained by Internet of Things network sensors, precedents of anomalous data, and their statistical and frequency characteristics. This formalization made it possible to identify implicit dependencies between objects, connect them with the characteristics of processes observed by Internet of Things network devices, and solve practical tasks. The problem of selecting characteristics that influence changes in information interaction patterns is considered. A survey of experts was carried out, and a Kano model was built to prioritize the characteristics that influence decision-making on the organization of an information interaction scheme in the Internet of Things network.

ONTOLOGY ENGINEERING
Approaches to automating processes of working with ontological resources
Resumo
Ontological models are extensively used in information support systems that offer resources and services for solving management, design, and scientific and technical problems. Specifically, domain ontologies are commonly utilized in decision support systems. In the ontological modeling of complex systems, there arises a need to automate the processes of handling ontological resources. This work discusses the main software systems and methodologies for ontological modeling, approaches to automating the processes of creating, populating, and using ontological models, and considers the temporal aspect of the ontological representation of objects. The aim of the work is to explore methods for automating the life cycle of ontological resources and to analyze the extent of their adaptation in applied ontologies. The work highlights a relatively high degree of automation in the process of populating ontologies and the use of large language models in this process. However, it points out the lack of methods for automating the conversion of information from tables and diagrams into ontological models, as well as for validating and processing the content of the model. Promising directions for automating work with ontological resources are also indicated.

METHODS AND TECHNOLOGIES OF DECISION MAKING
The structure of the CDSS information repository based on the ontological approach
Resumo
The construction of an information repository for a clinical decision support system (CDSS) in the weakly formalized subject area of treating bronchopulmonary diseases is considered. An overview of approaches to creating knowledge bases in this subject area is provided. A method for extracting knowledge is described, which is based on rules from clinical recommendations and the search for dependencies between words in sentences, taking into account the sequence of rule application. The information repository of the CDSS is populated with ontological and production knowledge bases using the proposed knowledge extraction method. An ontology for the selected subject area was developed, and studies of its quality were conducted through an analysis of the graph topology using cognitive ergonomics metrics. The effectiveness of the described knowledge extraction method is demonstrated. An original architecture for a clinical decision support system has been developed.

An ensemble of ontological models for intelligent support of laser additive manufacturing processes
Resumo
Barriers hindering the use of additive manufacturing processes for metal parts production are discussed. The necessity of integrating an intelligent decision support system (DSS) into the professional activities of laser additive manufacturing engineers is substantiated. The advantages of the developed ontological two-level approach for forming semantic information are highlighted. This approach's peculiarity lies in separating ontological models from the databases and knowledge formed on their basis—target information. The ontology dictates the rules for the structured formation and interpretation of target information. An ensemble of ontological models, forming the foundation of the developed intelligent system, is presented. The composition of the ensemble, the purpose of its individual components, and possible types of connections between them are described. The ensemble includes ontologies for reference databases on equipment and materials for laser additive manufacturing, an archive of protocols for technological operations of laser processing, a knowledge base about settings for laser processing modes, and a database of mathematical models. The ensemble of ontological models is implemented on the IACPaaS cloud platform using its tools. Ontologies, databases, knowledge bases, and a decision support system are part of the Laser Additive Manufacturing Knowledge Portal. Accumulating and using the knowledge and experience from different technologists in the portal will reduce the number of preliminary experiments needed to identify suitable technological modes and lower the qualification requirements for users of technological equipment.
