The development of modern technologies and innovations provides opportunities for higher education institutions (HEIs) and directly for teachers and students to voluntarily use tools for distance and mixed learning. However, remote access in a pandemic or a state of war is necessity and has no alternatives.The purpose of this study is to determine the role of the JetIQ electronic ecosystem for Vinnytsia National Technical University (VNTU) in wartime conditions. As in all HEI of Ukraine, the educational process at VNTU changed significantly during the year of military aggression. The need for students and teachers to hide in bomb shelters during air raids, frequent and, most importantly, unexpected interruptions of the educational process, and significant complications of access to laboratory equipment negatively affect the psychological state of all participants in educational activities. In these conditions, the JetIQ electronic ecosystem brought substantial benefits and became the primary tool for the management of the educational activities at VNTU. Reliable technological support also improved the psychological confidence of students and teachers. A comparison of the interim indicators of the 2022/2023 academic year with the trends of the three previous academic years in terms of quantitative indicators of educational resources and actions of all groups of JetIQ users showed positive trends. This testifies to its stability in the conditions of martial law.

The article contains the concept of building an IT strategy for the development of a higher educational institution, its information electronic systems, and the corresponding electronic information educational environment. The IT strategy can be presented as a separate document for the development of a higher educational institution or/and as part of its general strategy in terms of digitalization. The development of the electronic university is related to its target areas. Among them are the educational process, scientific research, management processes, information technologies, etc. These directions should be combined into a single integrated system. For the effective operation of such a system and the reduction of the payback paradox, it is necessary to determine not only the strategic directions but also the steps of their implementation. The basis for the implementation of such a strategy is the definition of the university’s development specifics and scenarios for IT strategy implementation. Research and practical implementation of learning management systems in higher education institutions of Vinnytsia allowed the development of a general concept of forming IT strategy development by using contours of the interaction of its agents. Each of its contours corresponds to the definite target of the development direction. It was determined that the digitalization implementation processes correspond to the expected strategic results. It is recommended to choose implementation scenarios by using the method of hierarchies which is based on the results of expert evaluation. The research results will make it possible to formulate recommendations for building and implementing an IT strategy for a higher educational institution. These recommendations are based on the determined performance indicators of the IT strategy and the results of the practical implementation of digitalization systems of higher education institutions in Vinnytsia.

The article contains the results of a study of the processes of automation of educational and management processes of higher education. The experience of the authors of the development and implementation of learning management systems and support for management of higher education, analytical studies of the need for automation of educational and support management processes revealed the need to measure the level of maturity of learning management systems and support for management processes (LMS&SMP). The variety of activities in higher education institutions is due to the need for research, development and implementation of teaching methods, organization of various projects, etc. On the other hand, the management of a higher education institution involves ensuring the level of quality of education, proper qualification of teachers and satisfaction of applicants for higher education. The latter are the target audience for the provision of educational services and key customers of such services. From the point of view of e-learning and blended learning systems, four categories of users have needs for automation: students; teachers; management; support staff. In accordance with their functional processes, it is necessary to create an electronic information educational environment with a high level of maturity of the learning management system and support management processes. In many cases, automated management systems of the educational process and management of the institution are almost unconnected, which, requires duplication of information. A comprehensive system of learning management and management support for higher education allows to form an effective information ecosystem from the level of an individual teacher, department to management. The proposed method of assessing the maturity of LMS&SMP allows to form a catalog of processes, the level of their automation, identify “white spots” of non-automated processes and design plans to improve the learning management system.

The urgency of the research. The behavior of agents as components of a learning management systems is being investigated at all stages of the life cycle of creating and using a software product. Learning management systems are characterized by the fact that the scenarios of their operation is associated with various aspects of educational activity. Directions of functional, emotional and motivational behavior of users are especially relevant. In addition, it is expedient to introduce software agents for the detection and prevention of crisis situations. Target setting. The purpose of research is deal with the close relationship between the behavior of users and the results of their activities in blended learning. The results obtained will test the basic functions of the system and identify their impact on user behavior. Actual scientific researchers and issues analysis. Recent research in various fields of science and practice focuses on user behavior, as well as the formation of special software modules (agents) that detect the problem moments of the system and warn the user. The algorithms of human-machine interaction, communications between users of information systems are studied by scientists from various fields of science and technology. Models of behavior of agents of the management training systems allow to verify the requirements to the system at different stages of the life cycle. For example, to identify the crisis moments of functioning, to consider organizational, motivational and emotional aspects. Uninvestigated problems. We have to focus the opinion on issues that require more detailed research and adaptation for learning management systems. They are: the definition of agents of information systems and their features in learning management systems; consideration of the system as a complex agent; definition of the main agent circuits of the electronic information environment on the basis of the training management system; models of agent behavior patterns and their relevance in the interfaces of program modules and user instructions. The research objective is to shape the behavior patterns of agents in the information management education system. The statement of basic materials. This research includes refinement of such basic definitions as the e-learning management system; the agent; the agent behavior pattern. Such definitions allow us to use the theory of mirrors and to determine the main contours of the functioning of the information system for blended learning in an educational institution. Detailed models are formed for the module of test final control and portfolio of the teacher. Formalized mathematical and informational models are the basis for studying of users behavior and the research basis of university blended learning system functioning. The implementation of the system modules was carried out according to the concept of “Electronic University”. The JetIQ VNTU system is implemented as a multi-agent learning system. Conclusions. The practical result of the exploration is the bundle of formalized models, definition of contours of the blended learning system and its modules. The checklist of the main processes of user behavior patterns and their description in user instructions forms the basis for analyzing of the existence of programing modules (agents) for warning, reminding and helping the user to work in particularly risky moments.

Blended learning is a modern trend in education. It enables the formation of synergies between traditional educational communications, electronic information dialogues and appeals to electronic resources. System algorithms of blended learning allow to use the method of “small steps” and to create a composition of interrelated educational processes. The purpose of the study is to identify key processes, roles of learners, learning situations and outcomes. A number of scientific and practical knowledge of authors and their practical experience are the base of this research and the introduction of its results into a practical educational process. Among them are the implementation of the method of “inverted class”, the active involvement of specialists and the formation of simulation model of practical activity students for future. The peculiarities of self-development in the direction of the management education platform and the teaching experience of the authors are the basis for making changes in the well-known approaches in blended learning of IT education. The purpose of the study is to identify key educational processes, to find algorithms of using internal and external electronic resources. The introduction of the proposed algorithms is tested during the teaching of disciplines “Algorithms and Data Structures”, “Fundamentals of Software Engineering”, “Project Management”, “Computer Networks” etc. The main changes in educational processes are: using of special network simulation software and project management software; using new approaches tests construction and encouraging students their mastering; the students' individual and teamwork in an education management system environment. The results of the research consist of determining role-based behavioural educational processes in management of education systems. The new opportunities for dynamics of improving of educational resources is based on involving practitioners, the using of open distance courses and the using of new forms of work with students. The question of activating the role of employers in the educational process and involving them in the evaluation of students' work, as well as the introduction of real cases, is an important issue.

Theoretical study of the photoelectric converter of light flux into voltage based on a pair of photodiode-operational amplifier is conducted. It is proved that the output voltage of the photoelectric converter based on the pair of photodiodeoperational amplifier linearly depends on the illuminated area of the photosensitive photodiode layer. A primary measuring converter of liquid level based on the considered photoelectric converter, in which the area of the illuminated photosensitive photodiode layer linearly depends on the level, and thus its output voltage are a linear level function, is proposed. Based on the proposed primary measuring level converter, a means of milk level measuring for a portable farmyard milking machine is implemented. The algorithm for its operation and algorithms for indirect measuring of milk yield, milk ejection intensity, latent period duration and other zootechnical animal parameters are considered. Absolute methodical error of measuring conversion of level and the absolute error of the proposed means of level measuring are determined. Modern means of individual milk yield measuring for farmyard milking machines, unlike stationary measuring means for milking parlors do not provide the accuracy, necessary for calculating and predicting certain zootechnical parameters. Therefore, measuring means that provides metrological indicators, similar to equipment, which is used in milking parlors, is created. As a result of implementing the created measuring means, the accuracy of indirect measuring of milk yield is increased, as confirmed by results of experimental studies. As a result of increasing the measuring accuracy of individual milk yield on farmyard machine, there is the possibility to abandon time-consuming procedure of control milking. Besides, accuracy of indirect measuring of other zootechnical animal parameters and further milking process optimization increases.

As a result of theoretical and experimental research, our statistic models of milking duration determine a functional connection between statistic parameters of the duration of conveyor milking machines operation, statistic parameters of preparing and milking a cow, parameters and varieties of milking machines, and the number of animals in the herd. The suggested models are based on a new approach to the estimation of statistic parameters of preparation and milking time. The models permit a more precise estimation of milking machines productivity at the stages of their design and modernization. The findings facilitate working out methods for designing information and measurement systems of milking technology parameters and automatic farm management systems and underlie further development of a theoretical background for such systems. The increased adequacy of the devised models in comparison with the current ones is proved through determining a relative estimation of the divergence between the theoretical findings and experimental data.
