A Pittsburgh bank is interested in improving the customer service at one of their branch offices while also reducing operating costs. The bank hasdecided that simulation could help them analyze their system.
Bank management would like to model customer arrivals accurately.
They also decided that they could provide the necessary customerservice with two full-time tellers (each having a break at designated times), one part-time teller to help during peak hours, and one manager available for the entire day.
Currently, customers arrive atthe bank and form a single line, waiting until a teller is available. Once a teller is available, the customer’s transaction is first reviewed for the next plan of action. This process usually takes 1minute, but can range between a low of 45 seconds and a high of 1.5 minutes.
Approximately 66% of the transactions require a simple transaction that the teller is able to perform alone. This simpletransaction usually takes 1.5 minutes, but can take anywhere between 1 minute and 2.25 minutes to accomplish. After this transaction, the customer exits the bank.
The remaining transactions are morecomplex and require the assistance of the manager for approval. These transactions require between 2 and 3.5 minutes. After this type of transaction, as with the simpler transactions, customers exit thebank. (Hint: Use a “Delay Release” with a delay of zero to release resources.)
The tellers and manager are scheduled as follows:
* Two of the tellers should be on duty from 9:00 a.m. to 5:00p.m.
* One of the tellers has a break from 11:00 a.m. to 11:30 a.m., while the other teller has a break from 12:45 p.m. to 1:15 p.m.
* The part-time teller will only work from 11:00 a.m. to3:00 p.m. (Hint: Remember to add zero capacity at end of work day.)
* The manager is on duty from 9:00 a.m. to 5:00 p.m. as well and takes a break when time is available (i.e., don’t worry about...
