Problem $15-25($Algorithmic$)$

Burger Dome sells hamburgers, cheeseburgers, French fries, soft drinks, and milk shakes, as well as a

limited number of specialty items and dessert selections. Although Burger Dome would like to serve each

customer immediately, at times more customers arrive than can be handled by the Burger Dome food

service staff. Thus, customers wait in line to place and receive their orders. Suppose that Burger Dome

analyzed data on customer arrivals and concluded that the arrival rate is $21$ customers per hour and $1$

customer processed per minute.

Compare a multiple$-$server waiting line system with a shared queue to a multiple$-$server waiting line system

with a dedicated queue for each server. Suppose Burger Dome establishes two servers but arranges the

restaurant layout so that an arriving customer must decide which server's queue to join. Assume that this

system equally splits the customer arrivals so that each server sees half of the customers. How does this

system compare with the two$-$server waiting line system with a shared queue? Compare the average

number of customers waiting, average number of customers in the system, average waiting time, and

average time in the system. If required, round your answers to four decimal places.

Comparing these numbers, it is clear that the

results in better process performance than the
