Markov chain modeling for quantitative safety analysis of multi-state systems with degradation, repair, and fault tolerance. Models state transitions including healthy, degraded, failed safe, and failed unsafe states with transition rates derived from failure rates and diagnostic coverage. Supports PMHF validation for complex redundant architectures, evaluation of diagnostic intervals, and assessment of repair strategies. Includes practical model construction, tool support, and validation against simplified calculations.
Markov Chains in Safety
Model degraded states, restoration rates, and failure transitions. Use Markov models for complex architectures and to validate PMHF and coverage assumptions.
