Josh Beckman (www.joshbeckman.org) Subscribe The most important notation that summarizes a queue: • ρ: utilization ratio = λ / μ Examples: • ρ = 1 means the arrival rate is equal to the service rate; the queue is staying the same size. • ρ > 1 means the arrival rate is greater than the service rate; the queue is getting larger. • ρ < 1 means the arrival rate is less than the service rate; the queue is getting smaller.
