Garg 1 Department of Statistics, Punjabi University, Patiala, India This paper studies a feedback queueing system with correlated departures. Departures take place only at transition marks. Inter-arrival times and inter-transition times follow exponential distributions. Transient-state queue length probabilities and laplace transform of the generating function of transient-state queue length probabilities are obtained. A few special cases of interest are also derived. Various probabilities relating the model are obtained numerically and are compared graphically. http://pubs.sciepub.com/ajna/2/1/5/ajna-2-1-5.pdf queueingfeedbackserverprobabilitygenerating functionnumerical solution
