Question

The cost of providing service in a queueing system increases with

• A. Increased mean time in the queue
• B. Increased arrival rate
• C. Decreased mean time in the queue
• D. Decreased arrival rate

Answer 1

Answer:

C. Decreased mean time in the queue

To decrease the mean time in a queueing system, additional resources must be deployed, which ultimately increases the cost of the service. Therefore, option 3 - decreased mean time in the queue - is the correct answer as it directly impacts the cost of providing the service. An increase in arrival rate and mean time in the queue also leads to an increase in cost, while a decrease in arrival rate leads to a decrease in cost
