Application of analysis of hierarchies in the choice of a method of automation of a companyAutomating a company’s business processes is an important part of optimizing its operations.
The automation process is a project activity based on the principles of achieving the goal, spending
resources and meeting deadlines. The choice of automation method depends on many criteria (preferences,
desires, technical and cost components) that must be considered in the planning of the project.
The method of analyzing hierarchies will make it possible to organize in the best way the decisionmaking
process regarding the choice of an automation method.
The hierarchy analysis method, developed by the American mathematician Thomas Saaty about
30 years ago, is still widely used in practice for making decisions in all subject areas. In matters of choosing
how to automate business processes of a company, this method is the best fit, because It makes it possible
in the best way to take into account in the project all the requirements for the future system, to ensure
the most acceptable functionality, to organize the most effective implementation and further support.
The effectiveness of its use in the selection of automation systems is demonstrated by the example of the
construction company PSK «Dom-skazka» engaged in automatization of business processes. To solve our
problem, six criteria were chosen. As a result of the analysis, a response was received, allowing to decide
on the choice of how to automate the production process. In the article, the authors consider an example
of applying the hierarchy analysis method in solving the problem of choosing an automation method.
The task has been set, alternatives have been chosen, selection criteria have been described, mathematical
calculations have been carried out and the results have been obtained, on the basis of which a reasonable
choice of the best alternative (automation method) has been made for the company in question.

Development of the architecture of an intelligent information system oracle programs blockchain management systemsOracle programs are a key link in the interaction of blockchain systems with the outside world. They must ensure the authenticity and security of data transmitted over a computer network to blockchain smart contracts. It is possible to increase security by creating a blockchain network for oracle programs, and a consensus of independent assessments of the authenticity of data in oracle programs will ensure the security of data transmitted to the main blockchain. Blockchain control systems in real time take several milliseconds to verify the authenticity of data, to data mining and to develop a control effect on the actuators. The consensus mechanism, which requires much more time, is not acceptable in these management systems.

Development of the architecture of a complex of industrial Internet of Things systems based on intelligent sensors and touchsensorsIn IIoT (Industrial Internet of Things) systems designed for enterprise management in real time, it is required to perform operational and intelligent processing of Big Data and issue a control signal to the actuators in a predictable time (on the order of several milliseconds). The high speeds of Big Data continuously generated by sensors of the industrial Internet of Things system make it difficult to obtain a control effect at a predictable time. The purpose of the study is to develop the architecture of a complex of IIoT systems to obtain a control effect at a predictable time in real time. The central issue of the task is the high-speed processing of structured data at the place of their occurrence to solve the contradiction between a large number of continuously generated necessary data and the need to process them at a predictable time. The decomposition of the IIoT system into separate IIoT systems according to the structures of the data used by them, followed by synthesis into a single complex of enterprise IIoT systems, is applied. The developed architecture of the IIoT system complex makes it possible to effectively implement distributed management of production processes in a predictable time, perform operational and intelligent processing of huge amounts of data of various formats continuously generated by industrial facilities. The complex of IIoT systems consists of separate systems of the industrial Internet of Things, each of which has its own structure of transmitted data and is implemented on the basis of a multi-level bus, which provides a high data transfer rate in a structured form, the ability to attach to the bus any IIoT device and any program used, including the Big Data system to identify hidden patterns in the work of the enterprise. The proposed solution of the architecture of the IIoT system complex based on intelligent sensors and touchsensors allows for effective management of enterprise equipment and technological process operations in real time with the immediate use of the new patterns found in the continuously incoming new data. The solution can be used by developers of industrial Internet of Things systems for the effective launch and implementation of projects, for the development and commissioning of IIoT systems.
