Research of the dependencies in variability of data reliability indicators in information and telecommunication systems

The article considers the basic control model for processes of the information reliability ensuring (ERI processes) in information and telecommunication systems (ITSs). The basic control model takes into account the temporality of reliability indicators assessment and the circulation of data resources (DRs) in the system under the set of factors influence. This article provides a solution of the problem of synthesizing the method for evaluating the data conversion operators influence on the values of information reliability criteria.
