Sectiоn D (Questiоn 5): Cоnsider а smаll post office with only one server аnd infinite buffer size. Interarrival times of customers are iid uniform (10,30) minutes (thus mean is 20 minutes and variance is 33.33 minutes2). Service times are iid normal with a mean of 18 minutes and variance of 81 minutes2 and independent of interarrival times. Show your work for all sub-problems on the scratch paper. (a) Give the most appropriate Kendall's queueing notation for the post office. [e] (b) What is the long-run fraction of time that the server is busy (i.e., utilization)? [a] (c) Calculate the squared coefficient of variation for interarrival times. [b] (d) Approximate the long-run average waiting time in queue in minutes. (Hint: WQ) [c] minutes (e) Approximate the long-run average number of customers in system. (Hint: L) [d] customers
