The server serves customers only in batches of two, and the service time (for a batch) has an exponential distribution with a mean of 1 unit of time. Thus if the server is idle and there is only one customer in the system, then the server must wait for another arrival before beginning service. The customers arrive according to a Poisson process at a mean rate of 1 per unit of time. (1). Draw the rate diagram. (Hint: think about how the state will change after one service completion.) (2). Set up the rate balance equations. (Hint: use the rate balance equations 1.) (3). Compute pn and L. (4).
