Yz. Yang et C. Knessl, THE UNCONDITIONAL SOJOURN TIME DISTRIBUTION IN THE QUEUE GI M-1-K WITH PROCESSOR SHARING SERVICE, Studies in applied mathematics, 93(1), 1994, pp. 29-91
We consider a processor shared GI/M/1 queue which can accommodate a fi
nite number K of customers. Using singular perturbation techniques, we
construct asymptotic expansions for the distribution of a tagged cust
omer's sojourn time. We assume that K is large and treat several diffe
rent cases of the model parameters.
