Recall that the equilibriun (optimal) utilization gives us the point at which the excess capacity -puequals the mean queue size (average number in the queue) EL. To help the grocery store manager, we can solve the optimal utilization p in terms of s by expressing pas (1/8")/, since each server is expected to take on 1/s* arrivals. The result is: AVT+1) Considering any one of the individual s* queues, derive the expected number of customers waiting in line Om 81 customers O b: 3.2 customers OG 0.9 customers Od 2.25 customers For any one of the individuals queues, what is the expected waiting time minutes) spent in line for a customer? O a. 15 minutes Ob. 38 minutes Oc '10 minutes Od 4 minutes Considering any one of the individuals queres, derive the expected expected number of customers in the system (waiting plus service) O 3 customers Ob 15 customers OC 9 customers + d. 4 customers Recall that the equilibriun (optimal) utilization gives us the point at which the excess capacity -puequals the mean queue size (average number in the queue) EL.
