A waiting line meeting the M/M/1 assumptions has an arrival rate of 4 per hour and a service rate of 12 per hour. What is the average time a unit spends in the system and the average time a unit spends waiting (in hours)?
What will be an ideal response?
Ws = 1 / ( ?- ?) = 1 / (12 - 4 ) = 1/8 or 0.125 hours; Wq = ? / [?(? - ?)] = 4 / [(12 )(8 )] = 1/24 or 0.0417 hours.
