A model for the selection of security system alarms

It was found that search engines provide a wide selection of detectors with technical characteristics. A significant range of characteristics ensures the use of detectors for solving problems in security systems. A search and sorting mode for security system alarms has been developed. It is based on the necessary and sufficient characteristics of detectors, which ensure their selection depending on the tasks set for security systems. Criteria for their selection are formed on the basis of user requirements and technical characteristics of detectors.

Methodological Recommendations for Digital Rating of Economic Indicators of Enterprises

The introduction of the economic rating will contribute to the centralization of control over the activities of economic entities by various state bodies. On the other hand, the economic rating will allow to avoid subjectivity in the evaluation of the economic activity of enterprises by state bodies and other subjects of economic activity and to establish a transparent and understandable work of the state bodies themselves for subjects of economic activity and society as a whole.


In modern conditions of society development, increasing degree and pace of integration of information technology achievements in the field of human life, traditional approaches to building information systems become too cumbersome or cease to be effective. One of the ways to solve this problem is to develop knowledge-based systems. The work is devoted to ontological modeling of a new subject area "travel organization". The ontology is considered in the context of knowledge exchange. The created travel ontology is quite modern and relevant today.

Development of PI-controller optimal tuning method

Aim. The research aims to develop a method of optimal PI-controller tuning, which allows to take into account the constraints and to minimize the undesirable indicators of the automatic control quality. Method. In order to carry out the investigation, the problem of optimal PI-controller tuning was stated in a general form. The analysis of the elements of the problem has been conducted. It allowed substituting the elements to the requirements of individual minimization criteria.

Reduction of phase interactions in control processes of “arc steel-making furnace – power supply system” complex electrical technological system

The article offers system engineering solutions for enhancing the single-phase autonomy of the processes of controlling the coordinates of electrical mode (EM) in an electrical mechanical sub-system of moving the electrodes of  an electric arc steel-making furnace by including a cross-link compensator into its structure.
