Queueing theory is applied to analyse a model of a multi-programming operating system in which preemptive priorities are used for scheduling the service of concurrent streams of requests. Preemptions are permitted at the end of each service quantum. Mean waiting times and the Laplace transforms of waiting times in the M/G/1 system analyzed are computed. The mean waiting times have been compared for the preemptive, non- preemptive and the studied disciplines in a queueing system described by way of example.
