Purpose of the study. The purpose of the study is to develop proposals for the formation of a neuroeducational environment that ensures that students acquire the competencies necessary to solve the problem of introducing end-to-end digital technologies within the framework of the digital economy program. The analysis showed that improving the training of specialists in the field of neurotechnology and artificial intelligence in the digital economy is an urgent and demanded task. The paper discusses an approach to solve the problem of improving the training of specialists in the field of neurotechnologies, taking into account the requirements of the federal project “Personnel for the digital economy” by creating a technological platform for a neuroeducational environment that ensures the acquisition of the necessary competencies by students. Materials and methods of research. In the process of carrying out the research, theoretical provisions in the field of the theory of neural networks were developed, a new class of neurons and neural networks was proposed, which are close in functions to biological neural networks and are called selective. The technology of training and application of selective neural networks has been developed. The advantage of selective technologies in comparison with classical neural networks is shown. Hardware models of neural networks, which are part of the neuroeducational system, have been developed and used in the educational process. A general methodology for teaching neural network technology as one of the end-to-end technologies of the digital economy has been developed, as well as a methodology for using neural networks in solving economic problems in the context of digital transformation. Results. A technological platform for a neuroeducational environment has been developed, including software, hardware models of classical neurons and perceptrons (McCulloch-Pitts), as well as neurons and perceptrons of a new class, called selective. A software tool for teaching standard and selective neurotechnologies was developed and proposed, for which a certificate of state registration of a computer program was obtained. For the assimilation of theoretical material and the acquisition of practical skills, methodological materials, author’s practical tasks and author’s laboratory works have been developed, which are part of the technological platform. The approaches proposed in the article can be used in organizing the study of the theory of neural networks and methods of applied application of neurotechnologies in solving the problems of introducing end-to-end digital technologies within the framework of the digital economy program. The development results are confirmed by 4 patents for inventions. In order to more effectively master the theoretical provisions and features of the practical application of neurotechnologies, the main attention is paid to the physical meaning and presentation of the processes occurring during the functioning of a neural network in the form of formal descriptions that provide a more effective assimilation of the foundations of the theory of neural networks and neurotechnologies using existing standard neural network architectures, as well as architectures built on the basis of selective neural networks. Conclusion. The architecture and components of the technological platform of the neuroeducational environment based on neuroeducational complexes have been developed. A general methodological approach has been developed for teaching the basics of neurotechnology based on standard and selective neural networks and the peculiarities of their application in the framework of the digital economy program. A methodology for teaching the basics of neurotechnology based on standard and selective neural networks has been developed, which includes the mathematical theory of standard and selective neural networks, a description of the learning process for standard neural networks based on McCulloch-Pitts neurons, as well as selective neural networks based on selective neurons.

Periodic solutions of the general free-fall three-body problem are investigated for the case of equal masses. The initial conditions are chosen on a Hill surface in form space. The use of the form space reduces the dimension of the problem and makes it possible to represent the region of possible initial conditions on the Hill surface, together with a color scale. The regions obtained can be used to improve the precision of the initial conditions for the periodic orbits in the free-fall three-body problem.

В статье представлен вариант построения модели рынка труда с помощью терминов и методов системной динамики с целью изучения процессов занятости населения, а именно соотношения спроса и предложения рабочей силы. Модели в статье реализованы в программной среде PowerSim Studio и отражают некоторые процессы, происходящие на рынке труда, благодаря которым формируется спрос на труд и соответствующее ему предложение рабочей силы. С помощью модуля оптимизации PowerSim Solver найдены решения, отражающие оптимальные значения параметров модели для различных ситуаций, выявляющие пути повышения эффективности работы предприятия. Далее проведено сравнение результатов, полученных без встроенного модуля оптимизации PowerSim Studio – PowerSim Solver и с ним. Первоначальные результаты по качественным характеристикам уступили полученным с помощью модуля, что говорит об эффективности его примирения в задачах изучения процессов занятости населения и демографии. Статья будет интересна преподавателям вузов, аспирантам и всем интересующимся системной динамикой.
