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?

Solutions

Expert Solution

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

Customers arrive at a two pump system at Poisson rate two per hour. An arrival finding the system empty is equally likely to enter service with either pump. An arrival finding one customer in the system will enter service with the idle pump. An arrival finding two others in the system will wait in line for the first free pump. An arrival finding three in the system will not enter. Two service times are exponential with rates one per hour...
