Conference paper


An approach to analysis of impacts of preventive maintenance on safety integrity level of a control system is presented in the paper. Suggested approach incorporates combination of Continuous Time and Discrete Time Markov Chain which allows full employment of advantages of Continuous Time Markov Chains as a stochastic modelling method. Deterministic behaviour of either periodic or non-periodic preventive maintenance is consecutively implemented through Discrete Time Markov Chain.
