Suppose you have a four-activity sequential process. Throughput capacities are shown in parentheses:

Task 1 (6) ---> Task 2 (5) ---> Task 3 (4) ---> Task 4 (6).

No buffers exist between tasks, so an upstream task must wait if the downstream task is busy.

Use this information to answer the next 3 questions.

What is the actual throughput rate out of task 4? Pick the closest answer.

a. 1

b. 2

c. 3

d. 4

e. 5

f. 6

2. What is the utilization for task 1? Pick the closest answer.

a. 10%

b. 25%

c. 33%

d. 50%

e. 66%

f. 75%

g. 90%

3. Which task(s) would be blocked? Check all that apply.

a. 1

b. 2

c. 3

d. 4

e. 5
