(2023). Safety Assessment of Maintained Control Systems with Cascade Two-Version 2oo3/1oo2 Structures Considering Version Faults. In: Zamojski, W., Mazurkiewicz, J., Sugier, J., Walkowiak, T., Kacprzyk, J. (eds) Dependable Computer Systems and Networks. DepCoS-RELCOMEX 2023. Lecture Notes in Networks and Systems, vol 737. Springer, Cham. pp. 88–98This work presents a macro model of operation for information and control system such as NPP RTS accommodating various failure types, in particular, faults of diagnostic and supervision means in both (main and diverse) subsystems. The paper continues investigating the microprocessor and FPGA based ICSs outlined. The object of the study is the process of ICS operation under conditions of failures caused not only by hardware and software version anomalies, faults of the diagnostic and supervision means and separated recovery of the ICS components.enSafety Assessmentsystemsfailure modelmacro modelMarkov availability modelresultsArticle
