【 摘 要 】

This paper deals with a reliability model of the restorable non-stop computing system with triple-modular redundancy based on independent computing nodes, taking into consideration the finite time for node activation and different node failure rates in the active and passive states. The obtained by authors generalized reliability model and calculation formulas for reliability indices for the system based on identical and independent computing nodes with the given threshold for quantity of active nodes, at which system is considered as operable, are also discussed. Finally, the application of the generalized model to the particular case of the non-stop restorable computing system with triple-modular redundancy based on independent nodes and calculation examples for reliability indices are also provided.
