Hierarchical Models of Markov Chains: Optimizations with Limited Pessimism
Original language description
Dependability models allow calculating the rate of events leading to a hazard state - a situation, where safety of the modeled dependable system (e.g. railway station signalling and interlocking equipment, automotive systems, etc.) is violated, thus thesystem may cause material loss, serious injuries or casualties. A hierarchical dependability model based on multiple Markov chains allows expressing multiple redundancies made at multiple levels of a system consisting of multiple cooperating blocks. Thehazard rates of the blocks are calculated independently and, when combined, they are used to calculate the hazard rate of the whole system. The independent calculations are significantly faster than the calculation of a single model composed of all models of the blocks. The paper shows a method of reducing Markov chains and using them to create hierarchical dependability models and its extensions allowing more accurate results to be achieved. An example study is used to demonstrate the i
