Arrival rate (λ): Average number of customers arriving per unit time.
λ = 1 / E(A) E(A) = average interarrival time
Service rate (μ): Average number of customers served per unit time (per server).
μ = 1 / E(S) E(S) = average service time
Utilization (ρ): Fraction of system capacity being used. Must be < 1.
ρ = λ / (cμ) c = number of servers
Coefficient of variation (CV): Measures variability.
Cₐ = σₐ / E(A), Cₛ = σₛ
