Abstract :
This paper deals with the performance analysis of a queueing system with rejuvenation controls. In particular, we describe the arrival process by the Markov-modulated Poisson process (MMPP) and consider a gradually degraded sever system. Under this situation, we discuss the system throughput of the queueing system and the optimal rejuvenation strategy maximizing the throughput based on the semi-Markov decision process in the case where the arrival and service rates are observable.
