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

Answer 1

The correct option is A increased mean time in the queue

Queuing theory deals with problems which involve queuing (or waiting).

In designing queuing systems we need to aim for a balance between service to customers (short queues implying many servers) and economic considerations (not too many servers).

The cost of providing service in a queuing system increases with increased mean time in the queue.
