    Notes: Abstract In this paper, we obtain strong approximation theorems for a single server queue withr priority classes of customers and a head-of-the-line-first discipline. By using priority queues of preemptive-resume discipline as modified systems, we prove strong approximation theorems for the number of customers of each priority in the system at timet, the number of customers of each priority that have departed in the interval [0,t], the work load in service time of each priority class facing the server at timet, and the accumulated time in [0,t] during which there are neither customers of a given priority class nor customers of priority higher than that in the system.

    Topics: Computer Science
    Notes: Abstract We consider a matched queueing network PH/M/c→oPH/PH/1, where the output of the first subsystem PH/M/c is regarded as one of the inputs of the second subsystem and matched with another input of PH-renewal process, and they are served by a single server with PH-service-distribution. The stationary state probabilities, the distribution of the virtual waiting times in the two subsystems, and the distribution of the total virtual waiting time are derived.

    Topics: Computer Science
    Notes: Abstract A sequence of shortest queueing systems is considered in this paper. We give weak convergence theorems for the queue length and waiting time processes when the sequence of traffic intensities associated with the sequence of shortest queueing systems approaches the critical value (ρ=1) at appropriate rates.

    Topics: Computer Science
    Notes: Abstract The computational problem of transient solutions for denumerable state Markov Processes (MP's) has been solved by Hsu and Yuan [12], who derived an efficient algorithm with uniform error. However, when the state space of an MP is of two or more dimensions, even for computational methods dealing with stationary solutions, only the case where one of the dimensions is infinite and all the others are finite has been studied. In this paper, we study transient solutions for multidimensional denumerable state MP's and give an algorithm with uniform error. Some numerical results are presented.
