A class of repairable fork-join queueing networks (RF .JQN) with finite queueing spacesand possible faliure and repairable servers is considered. The calculation methods for some interestedperformance measures (such as steady-state probatilities, steady-state queue length,failure probabilites of server and utilizable rates of server) in queueing theory and repairabletheory are obtained. Additionally, Parameters are optimized based on performance analysis.Finally, examples are given by simulation.
