The Baytown Post Office has four stations for service. Cus-tomers line up in single file for service on an FIFO basis. The mean arrival rate is 40 per hour, Poisson distributed, and themean service time per server is five minutes, exponentially distributed. Compute the operating characteristics for this op-eration. Does the operation appear to be satisfactory in terms of: (a) postal workers’ (servers’) idle time; (b) customer wait-ing time and/or the number waiting for service; and (c) the percentage of the time a customer can walk in and get servedwithout waiting at all?

Question
The Baytown Post Office has four stations for service. Cus-
tomers line up in single file for service on an FIFO basis. The
mean arrival rate is 40 per hour, Poisson distributed, and the
mean service time per server is five minutes, exponentially
distributed. Compute the operating characteristics for this op-
eration. Does the operation appear to be satisfactory in terms
of: (a) postal workers’ (servers’) idle time; (b) customer wait-
ing time and/or the number waiting for service; and (c) the
percentage of the time a customer can walk in and get served
without waiting at all?
