Scenario: A local bank is conducting a cost review of one of its drive-in window locations. Specially it wants to know the cost of manning its drive-in window operation using various numbers of customer service personnel to man its Multichannel, single-Phase system.
Accountants have assembled the following data:
Arrival Rate (assume Poisson distribution) per hour on average = 4 customers
Average Service Rate (assume exponential distribution) per channel per hour = 7 customers
Wait-time cost per hour = $41.50
Teller Wages & Benefits per hour = $37.00
Number of hours in operation per day = 8
1) What is the total daily cost (of the system) if one teller manned the drive-in window at this location?
- $2072.00
- $1412.00
- $1136.00
- $738.67
2) Using the data from Question 22. What is the total daily cost (of the system) if two tellers manned the drive-in window at this location?
- $920.00
- $855.13
- $798.58
- $986.67
3) Using the data from Question 22. What is the total daily cost (of the system) if three tellers manned the drive-in window at this location?
- $1206.88
- $1073.65
- $1193.20
- $1079.41
4) Using the data from Question 22. If three tellers manned the drive-in window what is the utilization rate of its tellers?
Please answer all the 4 questions related to Question 22. (multiple choices are given so you can please choose one when you work out)
