Suppose a fruit stand has two bank tellers, call them Sam and Paul. Sam services one queue, and Paul services another queue. The two employees consider whether the average number of customers waiting in the queue will decrease if they merge their queues. Sam recalls the PK$-$

Formula for the G$/$G$/$c queue is

Iq $2($c$+1)1-$ CA$2+$ CS$22$

and that this is the most general formula learned in COMM$204.$ Sam and Paul can use the

previous formula to determine the average number of customers in the merged

Queue.
