On average, 100 customers arrive per hour at the Gotham City Bank. The average service time for each customer is one minute. Service times and interarrival
times are exponentially distributed. The manager wants to ensure that no more than 1% of all customers will have to wait in line for more than five minutes. If
the bank follows the policy of having all customers join a single line, how many tellers must the bank hire?

- Zimmerman’s Bank is the only bank in the small town of St. Thomas. On a typical Friday, an average of 10 customers per hour arrive at the bank to transact business. There is one teller at the bank, and the average time required to transact business is 4 minutes. It is assumed that service times may be described by the exponential distribution. A single line would be used, and the customer at the front of the line would go to the first available bank teller. If a single teller is used, find: The average time in the line. The average number in the line. The average time in the system. The average number in the system.

- An average of 36 customers per hour arrives at a bank branch office (Poisson arrival) and wait in a single line to be served by the first available teller. The average time for each teller to service a customer is 4 minutes (exponentially distributed). Each teller earns $160/day and the bank branch office assesses a waiting cost of $50/day that a customer waits in the system. How many tellers should be on duty in this bank branch office to minimize the total cost of this waiting line system? 2 4 5arrow_forwardMarty's Barber Shop has one barber.

- Queuing theory refers to the fundamental concepts of a phenomenon that we constantly experience, the concept of queues. These queues are in production processes, such as in banks, service providers, etc.Based on the concepts of Production Modeling and Simulation, do the following: a) Assuming that cars arrive at a toll, on average, every 0.5 minutes, and the toll has only one payment window, and both the time between arrivals and the time between calls follow an exponential distribution. The toll attendant takes an average of 0.3 minutes to collect. Calculate the system performance measures, ie the car arrival rate and the toll service rate.arrow_forwardA small bagel stand known as Andres by the Sea offers drive-thru service to customers in Sants Barbra. Andres by the Sea has two customers arrive every hour on average. Suppose that this bagel stand follows an M/M/1 FIFO queuing system with no limits on queue length. They have one employee working at all times that spends 15 minutes per customer. Assume that the employee is paid $10 per hour and a customer’s waiting cost in queue is estimated to be $12 per hour. The average number of customers in the queue (before rounding up), and the total cost per hour are: a. 0.4; $15. b. 0.8; $18. c. 0.6; $21. d. 0.3; $17. e. 0.5; $16.arrow_forwardNeve Commercial Bank is the only bank in the town of York, Pennsylvania.

The arrival rate is 60customers per hour, and the average service time is fourminutes. The cost of each teller is easy to gauge at the$11.50 per hour wage rate. However, because estimatingthe cost per minute of waiting time is difficult, the bankmanager decides to hire the minimum number of tellersso that a typical customer has probability 0.05 of waitingmore than five minutes in line.a. How many tellers will the manager use, given thiscriterion?b. By deciding on this many tellers as “optimal,” themanager is implicitly using some value (or some range of values) for the cost per minute of wait-ing time. That is, a certain cost (or cost range) would lead to the same number of tellers as sug-gested in part a. What is this implied cost (or cost range)?arrow_forwardIn an M/M/1 queueing system, the arrival rate is 8 customers per hour and the service rate is 11 customers per hour.
