The correct application of the additive data aggregation mechanism in multi-criteria problems presented in various measurement scales requires that the initial estimates be transformed into the resulting homogeneous scales characterized by the same scope and number of gradations. At the same time, there is a problem of converting interval estimates into point estimates. The idea of the method for intersecting interval estimates and a large number of objects is to construct a histogram, and then equally divide the original measurement scale into segments, the numbers of which are identified with the point gradations of the resulting scale. An example of solving the problem of multi-criteria evaluation and comparison of a civil helicopter project relative to competitors in terms of tactical and technical characteristics and with interval-set sales prices is given.","PeriodicalId":504905,"journal":{"name":"Informacionnye Tehnologii","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140659335","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

IES are complex objects for design. The digital twin is a tool that allows one to integrate all the tools necessary for design in a single information space. Software tools that implement the digital twin of IES and are developed for their design require high flexibility in organizing calculations, which is due to the need to simulate a variety of equipment and involve a wide set of methods and mathematical models. Automating the construction of the computing subsystem is an effective solution to overcome the above difficulties. The article proposes a methodological approach to automating the construction of the computing subsystem of the digital twin of the IES. In accordance with the proposed approach, automated construction is performed on the basis of a software platform using modern metaprogramming tools. When building, the concept of Model-Driven Engineering is implemented and knowledge formalized in the form of ontologies is used. The article outlines the components of the proposed methodological approach to automating the construction of the computing subsystem of the digital twin of the IES, which include the following: principles of software platform development; software platform architecture; technique for automated construction of the digital twin computing subsystem; principles for ensuring the universality of software components. The digital twin obtained as a result of the practical application of the proposed methodological approach makes it possible to carry out computer and mathematical modeling of the IES in the virtual space, exploring various configurations of its construction. The implementation of modeling within the framework of the digital twin of IES makes it possible to implement flexible and efficient approaches to solving the problems of designing IES and to obtain design recommendations that can be implemented when building real IES.

We have described the sources of information to generate the data necessary for the application of AI methods. We have classified typical tasks of computer vision and navigation systems for solving using AI methods. We have analyzed the generally accepted classification of AI methods within the scope of the research subject. At the same time, special attention is paid to the features of AI methods that allow solving many well-known problems of recognition, approximation, optimization for UAS target and navigation tasks realization and effective operator support. In particular, we have considered neural networks, decision trees, support vector machines, k-nearest neighbors, genetic, ant colony algorithms, artificial immune systems. Currently, the hardware allows integrating complex algorithms based on these methods on board and widely using them in flight missions.

It is possible to improve the algorithms for generating synthetic electrocardiograms using mechanistic models and generative-descriptive neural networks (GANs). At the same time, when evaluating the effectiveness of the proposed solutions, various authors offer different quality assessment metrics from subjective expert assessment to the squared mean error. We compare two approaches to generating synthetic electrocardiograms: pseudo-ECG generation using a one-dimensional cardiomyocyte model and GAN based on long-term short-term memory in terms of machine learning metrics: accuracy, recall, f1-score. We solve the problem of binary classification with bagging method, class 0 — normal sinus rhythm, class 1 — atrial fibrillation. We found that classifier trained on synthetic ECGs generated using GAN is slightly more effective compared to pseudo-ECGs generated using mechanistic models ones. At the same time, it turned out that GANs are not stable enough. The generation of synthetic electrocardiograms using both mechanistic models and GAN can be used to enrich the training set in case of recognition of rare cardiac diseases.","PeriodicalId":504905,"journal":{"name":"Informacionnye Tehnologii","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-03-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140245362","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paradigm combines the possibilities of completely remote work of engineers in projects with deep adaptation of production and management processes (internal automation, communications visualization, risk management, etc.). To solve the actual scientific and practical task of determining the main properties of the new paradigm in the IT industry, industry studies for 2020-2023 were summarized and considered the sequence of influencing factors: from the use of geographically distributed development in software projects since the end of the last century to modern trends in workflow virtualization under the influence of the COVID pandemic and the use of artificial intelligence in software development. The paper also pays attention to the role and reasons for the emergence of a \"hybrid\" model for organizing the work of IT companies, when a team works together in the office several days a week, and several outside it. The results of the analyzed studies confirm that in 2023, fully remote work and the \"hybrid\" model are less and less dependent on the risks of a pandemic, are economically successful when used in the IT industry and create a completely new reality in the competitive struggle in the global IT market.","PeriodicalId":504905,"journal":{"name":"Informacionnye Tehnologii","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-03-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140247709","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
