If it takes 5 minutes to serve a customer at a fast food restaurant the service rate is _____. The _____ is the average number of customers who can be served during a given time period. The _____ is the frequency at which the customers arrive at a waiting line according to a probability distribution. Customers arrive at a candy shop every 8 minutes on average. The arrival rate is ______. If lambda = 12 and mu = 30, then utilization is equal to __________.

Solution

5 minutes to serve a customer => Service rate = 1 customer/5 minutes = 12 customers / hour

12 is the avg. no of customers served per hour.

At candy shop, Arrival rate = 1 customer/8 minutes = 7.5 customers/hour = 15 customers/2hour

Avg.Utilization = 12/30 = 0.4
