| Summary: | In the given paper the problem of Cyber-Physical Systems behavior analysis in the occurrence of faults is investigated.
To present the fault-free behavior of the investigated Cyber-Physical System as well as its behaviors in the presence of admissible faults, some Finite Discrete-Time Markov Chain is proposed and analyzed.
It is shown that a single stationary probability distribution exists for the proposed model.
This distribution is applied for characterization the behaviors of the investigated Cyber-Physical System in terms of the distance from the current fault to the set of critical faults.
Besides, the algorithm for bounded probabilistic reachability analysis of the target set of faults is proposed. |
