The article proposes a reliability model of a fault-tolerant majoritarian system with the {2 of 3} voting rule. In this model the effect of aging of both: the first set of core modules and reserve modules, which are included in the core during operation, is taken into account in an original way. Also, the traditional "false" determination of core failure rate of the majoritarian structure has been corrected. Consideration of the listed features in the model provides significant improvement of veracity the reliability indicators of such a system. The high level of adequacy of the reliability model makes it usable for solving problems of reliability synthesis of fault-tolerant majority-type systems. For example, to define the needed (minimum) number of redundant modules for a specified duration of operation of a fault-tolerant majoritarian type system without maintenanceDownloads
