Suppose a coffee shop order and fulfillment process is configured simply as a single queue with two steps: wait and service. Customers enter, wait their turn, and then are served, by placing and receiving their order all at once. Suppose that an average of 10 customers per hour enter the coffee shop while the shop is open. On average, there are two customers waiting in line to place their orders. It takes an average of 2 minutes to go through the service step, that is, it takes 2 minutes to complete the second step of placing and receiving the order. In steady state, O The average wait time before placing an order is 12 minutes. O The average time between customer arrivals is 5 minutes. O None of the answers are correct. There is an average of one customer being served at a time. O The average total time to wait and be served is 15 minutes.

For each of the following queuing systems, indicate if it isa single- or multiple-server model, the queue discipline,and if its calling population is infinite or finite:a. Hair salonb. Bankc. Laundromatd. Doctor’s officee. Adviser’s officef. Airport runwayg. Service stationh. Copy centeri. Team trainerj. Mainframe computer

A post office clerk operates with 75% utilization. The coefficient of variation for the service process is 0.6 and the coefficient of variation of the arrival process is 0.9. The average processing time is 4 minutes. What is the average time a customer spends in the system according to the single-server queue model? Multiple Choice ○ 7.02 minutes 4 minutes 11.02 minutes О 3.51 minutes
