Lightning Quiz – Lecture 17

In a priority queue system, what primarily determines the order of service?

• Order of arrival

• Random selection

• Predefined importance of users

• Time spent in the queue

All waiting users are equally likely to be served next under which queue discipline?

• First-in-first-out

• Priority service

• Service-in-random-order

• Last-in-first-out

At a ride-hailing pickup zone, passengers arrive randomly, and available drivers also arrive randomly to pick them up. Which of the following best describes this queuing system?

• M/M/m

• M/G/m

• G/G/m

• D/D/m

To ensure efficient queueing system performance, the operator should set the service rate identical to the arrival rate.

• True

• False

Suppose λ and μ denote the arrival and service rates in a queuing system, respectively. If both arrivals and service times are random, in which of the following cases there will be no queues in the system?

• λ < μ

• λ = μ

• λ > μ

• There can be queues in each case

A passenger arrives at a bus stop, waits for several minutes for the next bus, and then decides to leave to take an alternative mode of transport. This behavior is an example of:

• Balking

• Reneging

• Fixed Capacity

• FIFO Queue
