Customers arrive at the rate of 100 per hour. The ticket seller averages 30 seconds per customer. What is the average customer time in the system?
Arrival rate (λ) | 100 | customers per hour | ||
Service rate (μ) | 3600/30 | 120 | customers per hour | |
Ws = Average time spent in the system (waiting + service time) | ||||
Ws = 1/(μ - λ) | ||||
Ws = 1/(120-100) | Ws = 1/20 | Ws = 0.05 | hours | |
Ws = 3 minutes | ||||
