چکیده

Repairable standby system’s study and analysis
is an important topic in reliability. Analytical techniques
become very complicated and unrealistic especially for
modern complex systems. There have been attempts in the
literature to evolve more realistic techniques using simulation
approach for reliability analysis of systems. This
paper proposes a hybrid approach called as Markov system
dynamics (MSD) approach which combines the Markov
approach with system dynamics simulation approach for
reliability analysis and to study the dynamic behavior of
systems. This approach will have the advantages of both
Markov as well as system dynamics methodologies. The
proposed framework is illustrated for a standby system
with repair. The results of the simulation when compared
with that obtained by traditional Markov analysis clearly
validate the MSD approach as an alternative approach for
reliability analysis.
