Abstract The somewhat overlooked queuing model of Mn/G/1 is like the well-known M/G/1 (single server with a Poisson arrival process) but with one key distinction: The Poisson arrival process has queue-length dependent rates. This model was dealt with by Yoav Kerner. In particular, a recursion for the distribution functions of the residual (remaining) service time given the number of the customers in the system was derived. In this paper we add the feature that the server takes (repeated) vacations whenever he becomes idle. The arrival rate vary both with the queue length and with the status of the server. We derive the corresponding recursions for this model. We note that the importance of having such results is in assessing the waiting time given how many are ahead upon arrival. *** Important *** Note the unusual day, time and location.
