Question

Job candidates are leaving an office every 50 minutes. Each candidate goes through three activities during the office visit: verification, written test, and interview. Verification takes 1 minute, the written test takes 40 minutes, and the interview takes 10 minutes. Assume there is only one resource dedicated to each activity. What is the utilization of the bottleneck resource?

Answer 1

Answer:

80%

Explanation:

Calculation to determine the utilization of the bottleneck resource

First step is to calculate the Flow rate

Flow rate = 1/50

Flow rate = 0.02 customer per minute.

Second step is to calculate the Bottleneck capacity

Bottleneck capacity = Min(1, 1/40, 1/10)

Bottleneck capacity= 0.025 customer per minute.

Now let determine the Utilization of the bottleneck resource using this formula

Utilization of the bottleneck resource = Flow rate/Capacity

Let plug in the formula

Utilization of the bottleneck resource= 0.02/0.025

Utilization of the bottleneck resource= 80%.

Therefore the utilization of the bottleneck resource is 80%
