ON THE PROBLEM OF CONTROL THE RELIABILITY OF AN INFORMATION SYSTEM UNDER CONDITIONS OF INTERVAL UNCERTAINTY

In the course of the study, aspects of the power supply of information systems are considered in the case of uncertainty described by interval-type data, and the main types of errors that arise during their operation are studied. The aim of the study is to find effective approaches to ensuring reliable operation of information systems subject to the presence of uncertainty in the values ​​of parameters specified by interval data. Materials and methods. This article presents an approach to solving the problem of control the reliability of a complex information system in the presence of an uncertainty factor in the values ​​of parameters that can be described using interval type data and the corresponding mathematical methods for working with them The scientific novelty of the described approach lies in the ability to most accurately take into account the error factor that occurs when an information system operates under conditions of uncertainty and determine the optimal options for correcting the values ​​of its parameters, without allowing their changes to go beyond the permissible intervals. Conclusion. The approach proposed in the article is supposed to be used when solving the problem of ensuring reliable operation of an information system in the presence of uncertainty, which can be described using the apparatus of interval data. The developed method makes it possible to find the optimal control effect on the system parameters at a given time, at which the probability of failures will be minimized.
