ASSESSMENT OF THE IMPACT OF THE INFORMATION AGING FACTOR ON IT CERTAINTY

The method of sequential redundancy allows to significantly reduce the probability of false alarms at “zero” economic costs, but the application of this method is limited by the time of information aging and correlation links of random self-correcting failures of equipment. The mathematical model of taking into account the influence of the factor of information aging on its reliability in control systems is developed, and correlation links between successive inputs of information are also taken into account. On the basis of statistical modeling (Monte Carlo method) the analysis of conformity of theoretical and practical results taking into account the factor of information aging is carried out. The method of sequential information redundancy is easily realized on microprocessor systems, which are now widely used.
