Queueing Model Calculator — PSO Petrol Pump

Select a queueing model → Enter arrival/service inputs → Choose distributions (where applicable) → Calculate

Core Inputs
All times/rates below are interpreted in this unit — no manual conversion needed.
For record/reference — steady-state formulas below assume an infinite population.
Arrival Input
λ = 1 ÷ this value.
Service Input
μ = 1 ÷ this value. (Also the mean used for Normal service.)
λ (Arrival Rate)0.3333 /min
μ (Service Rate)0.5000 /min
ρ (Utilization) = λ / μ — must be < 1 0.6667
