6. Consider the following process. All steps (A, B, C, D, and E) are necessary to create each finished unit. Each step employs a single worker. Task times are shown for each step.

What is the hourly capacity/throughput rate/flow rate of the process above?

a. 12

b. 5

c. 6

d. 48

e. 31

7. A motherboard workstation produces 1,000 motherboards in 20 seconds. Bottleneck time of the motherboard workstation is 50 motherboards per second.

a. True

b. False

8. Consider a five-workstation, worker-paced line, with five manual tasks to be performed before the product is completed, as diagrammed below:

Management is contemplating adding a seventh experienced senior worker, as a floater, to this line. This worker is fully trained to do any of the five tasks, and would move around freely, doing whatever was best to maximize the output of the process. What would then be the lines MAXIMUM capacity/throughput rate/flow rate, in units per eight-hour day?

a. 60

b. 54

c. 72

d. 64

e. 40

9. An assembly line has 5 stations with times of 1, 5, 7, 4, 10, respectively. What is the bottleneck time?

a. 37% of the throughput time

b. 100% of the throughput time

c. 2.7% of the throughput time

d. 27% of the throughput time

10. Consider a five-workstation, worker-paced line, with five manual tasks to be performed before the product is completed, as diagrammed below:

The times shown are the times, in minutes, that it takes one worker to perform that task for one unit of product. This line is staffed with six workers, two of whom are assigned to Workstation D. For the next three questions, assume that each of the Tasks A through E are never split among multiple workers. Thus, the two workers doing Task D work on every other unit, each doing all of Task D on the particular unit on which he or she is working. (Assume there is ample equipment so that all workers can perform their tasks). What is the lines capacity in 8 hours day?

a. 96

b. 12

c. 40

d. 51

e. 5
