- •
Systematic approach of Markov modeling for system dependability analysis is proposed based on the independent subsystem set, its failure rate and unavailability rate.
- •
As an application example, we construct the Markov model for the digital reactor protection system configured with four identical and independent channels, and various fault-tolerant architectures.
- •
The result shows that the proposed method treats complex architecture of the system in an efficient manner with Markov model's merits such as time dependent and sequential analysis.
