摘要：
In the presented work the idea of improvement the state space method for building safety models of complex technical systems for critical application is proposed. Result of the this improvement one single model is developed on which due to the split state of critical failure state quantitative reliability and safety quantitative indicators of the system can be obtained. Unlike traditional models as in a fault trees, dynamic tree failures and FMEA/FMECA-models the proposed model to allow to take into account independencies between accidental situations. This model allows to investigate the trend of risk indicators accidental situations variance from increasing system reliability through the use of fault-tolerant configurations and maintenance usage.
