Question

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?

• 0.190
• 0.250
• 0.267
• 0.222
