摘要：

Traditional availability, reliability, and safety models face the dimension problem due to a huge number of components in modern systems, motivating further research in this field. This paper focuses on multi -fragmental and multiphase models for availability and functional safety assessment of the information and control (I&C) systems with two -cascade redundancy considering design faults manifestation during operation. The methodology of the research is based on Markov and semi-Markov chains with the utilization of multi -phase modeling. Several multi -phase models are developed and investigated considering different conditions of operation and failures caused by version faults. The case study of the research is based on the analysis of safety -critical nuclear power plant I&C systems such as the reactor trip systems developed using the programmable platform RadICS.
