Markov chains hierarchical dependability models: Worst-case computations
Original language description
Dependability models allow calculating the rate of an event leading to a hazard state ? a situation, where safety of the modeled dependable system (e.g. railway station signaling and interlocking equipment, automotive systems, etc.) is violated, thus thesystem may cause material loss, serious injuries or casualties. A hierarchical dependability model allows expressing multiple redundancies made at multiple levels of a system decomposed to multiple cooperating blocks. A hierarchical dependability modelbased on Markov chains allows each block and relations between these blocks to be expressed independently by Markov chains. This allows a decomposition of a complex dependability model into multiple small models to be made. The decomposed model is easierto read, understand and modify. A hazard rate is calculated significantly faster using hierarchical model, because the decomposition allows exponential calculation-time explosion to be avoided. The paper shows a method how to reduce Mark
