Item Functional networks for ergonomics and reliability tasks on the 90th anniversary of A. Gubinsky and V. Evgrafov(Sigurnost, 2022) Лавров, Євгеній Анатолійович; Лавров, Евгений Анатольевич; Lavrov, Yevhenii Anatoliiovych; Siryk, O.E.The paper considers the tasks of discovering ergonomic reserves for increasing the reliability and efficiency of automated systems. The authors show the necessity of using the Activity Approach and the Theory of Functional Networks, developed by the scientific school of Professor Anatoly Ilyich Gubinsky. The authors describe the history of Functional Networks approach and the current state of development of the functional networks models and show the possibilities for automating the assessment of reliability of human-machine interactions. The research describes the common ergonomics issues and its effective solution by the introduction of automated procedures for the analysis and evaluation of functional networks. The authors further present the ways of using the developed models in decision support systems in the automated systems design and operation.Item Human-centered management in polyergatic information systems. Multi-criteria distribution of functions between operators(IOP Publishing Ltd, 2022) Лавров, Євгеній Анатолійович; Лавров, Евгений Анатольевич; Lavrov, Yevhenii Anatoliiovych; Siryk, O.E.; Чибіряк, Яна Іванівна; Чибиряк, Яна Ивановна; Chybiriak, Yana Ivanivna; Zolkin, A.L.; Sedova, N.A.The article considers the problem of human factor in complex polyergatic systems with a flow of applications for functions (problem-solving) arising at random moments of time. The structure of a decision support system for the operator-manager, including subsystems of monitoring, forecasting and decision-making, is justified. The system of criteria relevant to solving the tasks of functions distribution was substantiated and its multi-criteria nature was shown. The technology of multi-criteria evaluation and choice of alternatives based on the methodology of hierarchical system analysis of problems and the method of analysis of hierarchies, Thomas Saaty has been proposed. The decision-making system, which has been tested in the operation of control systems of various complex technical and production objects, has been implemented. The proposed method differs from the known approaches in that this method is aimed at prompt decision-making, as well as in that it uses a multi-criteria approach and both pragmatic and ergonomic criteria are used as criteria.Item Creation of a software and hardware product of a real-time system for collecting, accounting and managing data transmission of an intelligent transport system in context of the IoT(IOP Publishing, 2021) Zolkin, A.L.; Munister, V.D.; Лавров, Євгеній Анатолійович; Лавров, Евгений Анатольевич; Lavrov, Yevhenii Anatoliiovych; Aygumov, K.G.; Saradzheva, V.Some aspects of the functioning of modern microcontrollers of the Internet of Things in conditions that are close to real-time systems are reviewed in the article. Attention is paid to the aspects of the theory of physical data transmission, the significance of the delay metrics in the data transmission path is substantiated and emphasized. These delays (in view of the generalization of measurement results) determine the control accuracy and controllability of the data processing system as a whole, and also affect the reliability of the results. The process of formalization of the architectural template of a data collecting and accounting system for a control device (which is widespread in intelligent transport systems and the Internet of things) is described. The practical application of the approach in synchronous control through the implementation of a web interface and a control language in a microprocessor system (which can be possible at low traffic transmission rates) is substantiated. In conclusion, a generalization of the scope of application of the developed specialized computer system in transport field is given.Item Method for assessing the information content of factors forming the cognitive independence of students(IOP Publishing, 2021) Лавров, Євгеній Анатолійович; Лавров, Евгений Анатольевич; Lavrov, Yevhenii Anatoliiovych; Logvinenko, V.; Siryk, O.; Kyzenko, V.The article describes the problem of awakening the cognitive activity of students, arising due to revolutionary transformations in teaching technologies. It shows the need to study the factors that affect cognitive activity and assesses the information content of those factors. Based on the method of pair comparisons, a technology for ranking the factors affecting cognitive activity has been developed. A mathematical model of the formation and processing of expert assessment results and an example of calculations are given, and the feasibility of including the subsystem for evaluating factors affecting cognitive activity in the computer control system of the university is shown. The structure of an adaptive e-learning system based on the technology of taking into account the factors that form the cognitive independence of students is described Experiments carried out in 3 universities of Ukraine have shown that the use of the developed mathematical model and information technology allows to increase significantly academic performance and to decrease the frequency of refusals from independent work of students using the e-learning environment.Item Issues of organization of expertise and problems of expert assessments(IOP Publishing, 2020) Padern, P.I.; Burkov, E.A.; Лавров, Євгеній Анатолійович; Лавров, Евгений Анатольевич; Lavrov, Yevhenii AnatoliiovychIn the course of preparation and carrying out of various expertises, in a number of cases methodological and organizational problems arise due to both the insufficiently high level of training of the working group members who develop the program and methodology of the expertise, and various restrictions, that could have a material impact on the credibility of the results. These restrictions generally are either financial in nature or are associated with a lack of sufficiently qualified and objective experts in the subject area. Objective: to develop a set of techniques that allow to expand the possibilities of using expert assessment methods in the preparation and carrying out of modern expertise in the presence of restrictions associated with external conditions. Methods: methods and approaches of system analysis, integration of individual expert assessments are used. Results: a comprehensive analysis of the problems faced by specialists in the organization of various expertises has been carried out. A number of techniques have been proposed that make it possible to significantly simplify the process of preparing and carrying out expertises but at the same time do not negatively affect the adequacy of the results obtained. Practical significance: the results obtained can be widely used in the course of various expertises, both in the process of selecting experts and in the process of direct obtaining and combining expert assessments. In addition, the use of obtained results in terms of different organizational and material restrictions will allow to expand the scope of possible applications of expert assessments. Prospects: the proposed approach and the set of techniques lay the methodological basis for creating a decision support system that will give specific recommendations to specialists involved in the development of program and methodology of the expertise at all stages of their activities. The introduction of such a system will greatly contribute to the simplification of various expertises, and will also increase confidence in their results.Item Информационная технология оценивания психологических факторов рабочего места человека-оператора(Сумский государственный университет, 2017) Кротевич, К.Н.; Лавров, Євгеній Анатолійович; Лавров, Евгений Анатольевич; Lavrov, Yevhenii AnatoliiovychПостановка задачи.
