Many companies transfer their business processes to the Internet, and provide users with access to their data, solutions and services. In this regard, there is a shortage of IT specialists of this qualification — web developers. And if we take into account the rather rapid change of technologies, which concerns both programming paradigms and just the release of new versions of software, such as server, programming languages, programming system, frameworks, then methods of professional development of web developers become especially relevant. The purpose of the study is to determine the most effective way to develop a web developer in the company. This includes determining the needs of the company and the skill level of the developer and reducing the difference between these indicators. The task is to determine the method of optimal assessment of the level of qualification, offer points of measurement of this level, and analyze the effectiveness of advanced training. The article raises the problems of effective professional development of employees of web development companies. The way of development of a ready-made specialist is considered, depending on the skill level of the developer, the level of project requirements and updating of the main software. Methods used: empirical research, classification methods. The methods of evaluation and training of employees were analyzed using the example of companies leading web development. The result of the research is a model of web developer competencies, recommendations for assessing the levels of knowledge and skills of employees, recommendations on the level of implementation of new technologies.","PeriodicalId":37476,"journal":{"name":"Radioelektronika, Nanosistemy, Informacionnye Tehnologii","volume":"43 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-08-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87572191","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}

Rodzin","doi":"10.17587/it.29.423-436","DOIUrl":"https://doi.org/10.17587/it.29.423-436","url":null,"abstract":"The work is devoted to solving the scientific problem of decision support for the prevention and elimination of emergency situations (ES) consequences based on fuzzy logic and machine learning methods. The relevance of this problem is due to the need to optimize the risk of adverse effects on human health and the environment in connection with emergency situations. The increased complexity of the tasks solved within the framework of the designated scientific problem is associated with the presence of information uncertainty in the complex accounting of heterogeneous characteristics, which in some cases can’t be normalized and brought to a single measurement scale. In such conditions, information processes for predicting the occurrence of potentially dangerous chains of events in the technogenic and natural spheres must be built using artificial intelligence methods and fuzzy logic to increase the efficiency of choosing the sequence of actions performed on the available information in order to build the necessary models, methods and algorithms to eliminate negative development situations and ensure monitoring of emergencies potential development cases. The authors give formalized statements of the tasks to be solved. A conceptual data model is proposed for constructing fuzzy decision support rules for the prevention and elimination of emergencies’ consequences. One of the options for formalizing such a data model is the transition to a vector representation of the information space. This will allow in the future to solve the problem of their classification on a set of information elements for distribution by classes of emergency situations. The criterion for evaluating belonging to a certain class is the argument for minimizing the distance between information elements in the vector space. The procedure for the accumulation by an intelligent system of precedent models set for the prevention or elimination of the emergencies consequences, which is a stage of machine learning, is described. After passing it, the intelligent system becomes capable of assessing the semantic similarity of operationally obtained models with precedents that have already fallen into the category of templates. The criterion for evaluating the effectiveness of an intelligent decision support system is the semantic similarity of the operational situational emergency model and the precedent model. A heuristic algorithm for determining semantic proximity was proposed. In order to optimize the time spent on supporting decision-making on the prevention and elimination of the emergency situations consequences, the authors also propose to use decentralized bioinspired methods, the advantages of which are internal procedures that provide diversification of the search space to exit from local optima and quickly obtain quasi-optimal solutions to the problem.

In machine data formats, the digit grid of typical and specialized computers displays numerical values on which calculations are performed in various number systems. A new modular packed representation of numerical values by rational fractions with fixed denominators, previously unknown, is introduced. For such modular representations of numerical quantities, a basic algorithm for the formation of vector components of types of representations is given with an estimate of complexity. A method of optimal approximation by packed modular representations of arbitrary irregular fractions has been found.

Bochkarev","doi":"10.17587/it.29.437-444","DOIUrl":"https://doi.org/10.17587/it.29.437-444","url":null,"abstract":"In 2021, at the Obukhovo station of the Oktyabrskaya railway. testing of the technology for counting the number of operations of relay equipment began. The results of testing the technology at the Obukhovo station showed that relay equipment with a high intensity of operation generates faster the standard number of operations specified in the technical specifications for the equipment. Relay equipment with a high intensity of operation needs to be replaced earlier than the scheduled period, and equipment with a low intensity of operation needs to be replaced less often than the scheduled period. The routine method of replacing relay equipment does not take into account the intensity of its work. The article proposes a scientific approach that allows you to manage the resource of the relay equipment of railway automation and telemechanic at the stage of its operation based on the calculation of the timing of its replacement. To calculate the timing of the replacement of relay equipment, objective data on the values of their actual number of operations are used. The article proposes the calculation of the timing of the replacement of relay equipment based on its characteristics, service life under technical conditions, scheduled terms in the instructions, and the intensity of its work. The calculation of the cost of failure and maintenance of relay equipment over the entire service life is given to determine the optimal replacement period for relay equipment, for which the replacement period occurs earlier than the scheduled period. The calculation of the timing of the replacement of relay equipment makes it possible to switch from the scheduled maintenance method to maintenance based on the actual state and ensure the transition to address planning. This will reduce labor costs for maintenance and the risk of relay equipment failures.","PeriodicalId":37476,"journal":{"name":"Radioelektronika, Nanosistemy, Informacionnye Tehnologii","volume":"76 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-08-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86381700","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 article is focused on the development of the multimodal route network model that leverages on only the pertinent suite of source abstract object types, which preliminary differentiate according to the open architecture of categorized types. The main emphasis is on the detection of relevant associations, which take place into the transportation domain being modeled, and constraints on its populations. One of these restrictions is the base segment constraint, which guarantees correct instances of the specialization segment relationship. The model contains formal expressions for verifying data reliability in terms of segments specialization, coherence and sequence order of the latter in routes. Another group of constraints encompasses the terminal pool restrictions that comprise constraints of the sequence order, non-redundancy, and unique combinations of source and destination route points. All terminal constraints have been formalized by means of the relational algebra operators. Such decision is capable of supporting integrity constraints by using triggers or stored procedures of database management systems. We have also exploited the universal structural primitive for the multilevel representation of entity lists, as well as have demonstrated the role and function of dedicated datasets under the forming of links between entities.","PeriodicalId":37476,"journal":{"name":"Radioelektronika, Nanosistemy, Informacionnye Tehnologii","volume":"28 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-08-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82601404","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}
