Analysis of the structure of an intellectual information system based on the concept of functional stability

Abstract

The development of modern society requires intensive development of information technologies with a high degree of autonomy. This issue is especially acute for production enterprises that operate under the influence of destabilizing factors. In this work, research on the property of functional stability continues. Functional stability means the property of an information system to maintain its functioning, possibly with a decrease in quality, during the specified time under the influence of external and internal destabilizing factors. External and internal destabilizing factors mean failures, failures of system modules, mechanical damage, thermal effects, errors of service personnel. The main stages of ensuring functional stability are the detection of the module that failed during control, the diagnosis of the module that failed, and the restoration of the functioning of the intelligent information system. A feature of intelligent information systems is that they must function autonomously. With their help, it is possible to ensure an increase in the labor productivity of all production centers while reducing the number of people employed in production. The purpose of the work is to build a mathematical apparatus for quantitative assessment of the functional stability of the data exchange system of the intelligent information system. In addition, this article shows the advantages of using quantitative methods of assessing functional stability based on such indicators as the limit and margin of functional stability. On the basis of these assessments, recommendations can be made for building an intelligent information system. In addition, the evaluation data will help to more clearly formulate the requirements for the structure of the intelligent information system, which will be designed for uninterrupted data transmission.
