Estimation of one indicator of functional stability in case of periodic effects on elements of information system

Nowadays, assessing the dynamics of functional stability in information systems is a highly relevant task across various fields. This issue becomes especially important when the information system operates autonomously. In such cases, accounting for random effects is crucial, necessitating the development of methods for evaluating functional stability indicators that consider this factor. In this work, the authors propose a method for estimating the probability of connectivity under periodic random effects during the operation of the considered information system.
