Letter to the Editor—Some Remarks Concerning the Departure Process of a Queue with Poisson Arrivals and no Balking

This note gives a technique to obtain for a queue with Poisson arrivals and no balking, the joint distribution of the number of departures during (0, t⌋ and the queue length at t from the marginal distribution of the queue length at t. As an illustration the joint distribution for the queuing system M/G/1 is given.
