The paper deals with complementary changes in scientific research and real economy (exemplified by the farming industry) taking place when using the holistic approach to the industry”s digital transformation resulting in the appearance of precise agrarian technologies that require a comprehensive., system-based combination of research and production resources that are able to ensure increased productivity in the industry. We demonstrate that among these new technologies, the artificial intelligence methods have a special significance. They have to, however, go through integration transformations to become standards for the proposed common digital farming management platform

This work addresses the problems of analysis and synthesis of software and data ware for distributed data processing systems operating in real time. The paper presents formal models and algorithms for calculating the average and maximum processing time of various requests

The problem of stabilizing a chain of three integrators subject to a phase constraint is studied. Continuous constrained control in the form of nested sigmoids, which guarantees the fulfillment of the phase constraint, is synthesized. A Lyapunov function is constructed, and necessary and sufficient conditions of global stability of the closed-loop system are established. The discussion is illustrated by numerical examples.

The article is devoted to the technology of constructing generalized risk factor for evaluation of objects considering their expert probability, including technical projects, enterprise development strategies, construction of regional facilities, and so on. The construction of a generalized risk factor assessment of objects with a multi-level structure results an issue of constructing the result-ing scale. The relative degree of losses is generally characterized by weights of risk factors. The level of risk consequences and respective subjective probability are usually presented as the form of a square matrix - a risk map. Risks areas with verbal interpretation are accepted as a general-ized assessment. The article proposes a new method for transitioning from the initial assessment of risk factors considering the expert probability to point estimates on the resulting difference scale based on the technology framework of constructing a generalized risk assessment of objects with a multi-level structure. The essence of the method is originally reduced to the transition from the initial point estimates in the point scale to the interval gradations of the resulting scale. Subsequently, given the subjective probability, one transits to point estimates of the resulting dif-ference scale.

Исследуется устойчивость системы с переключениями, возникающей при применении обратной связи в виде вложенных сатураторов для стабилизации интегратора 2-го порядка. Использование обратной связи в виде вложенных сатураторов позволяет легко учесть ограниченность ресурса управления и обеспечить выполнение фазового ограничения на скорость приближения к положению равновесия, что особенно важно при больших начальных отклонениях. Построена функция Ляпунова замкнутой системы, с помощью которой доказана ее глобальная асимптотическая устойчивость при любых положительных коэффициентах обратной связи
