12-2: Suppose that the service rate to a waiting line system is 10 customers per hour (exponentially distributed). Analyze how the average waiting time is expected to change as the arrival rate varies from two to ten customers per hour (exponentially distributed). What is the Average waiting time in queue with Lambda = 2 & Mu = 10.00 ?

A.0.03

B.2

C.3

D.6

Solution

Average waiting period = Lambda / (Mu *(Mu-Lambda))

= 2/(10*(10-2))

= 1/40

=0.025

=0.03
