Abstract: Queueing systems with state-dependent arrival and service rates along with catastrophes are investigated. Explicit expressions for the transient probabilities of system size are obtained. The corresponding steady-state probabilities are deduced. Busy period distribution is also found. Some performance measures are obtained for the system. Extensive numerical illustrations are provided. It is observed that the limiting distributions do not exist in the absence of catastrophes.

Keywords: time-dependent analysis; chain sequences; continued fraction; steady state probabilities; busy period; Markovian queues; total catastrophes; busy period distribution; transient probabilities; system size. (search for similar items in EconPapers)
