Abstract

Using the Continuous Time Markov Chain to analyze the reliability of a computer system, our research shows some corrections for the Constantopoulos, Doerr and Petraki’s papers. We further developed a Markov modeling for a system with 4 copies of data to fulfill the sample reliability rate set by the RLG-NARA. The Markov modeling described can be used to calculate the reliability of any systems to ensure readability of bit-streams.
