【 摘 要 】

This scientific paper deals with the reliability model of the symmetric system based on two data processing nodes with the functional redundancy. The simplified reliability model of the system and the advanced model offered by the authors considering nonzero time of activation of the node primary functions, nonzero times for node failure detection and switching to the function backing-up mode are presented. The formulas for calculation of stationary availability factor, mean time to failure and mean time to repair are also discussed. Finally, the examples of reliability indices calculations according to the simplified and advanced reliability models are also given.
