Problem 3 Queues Let us say you are in a line at the video store or bank like I was last weekend. One line, yet there are 3 clerks/tellers which service the same line. Simulate the following, Clerk 1 - Services customers on the average 1/min Clerk 2 - Services customers on the average 0.5/min Clerk 3 - Services customers on the average 0.75/min Customers- Arrive at 4/minute intervals. When the line gets to 5 customers add one more Clerk with the same service rate as Clerk 1. Add one more clerk similarly for each 5 customers. Take tellers away when they have serviced the line according to how they were added. For instance, if a 4th clerk was added to the line because there were 5 customers waiting then remove the clerk when the customer count in line goes to zero. What is my average customer wait time? What is the max number of customers in the line. If you randomize servicing and arrival times by +-80% how does this change the results
