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.

1) 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
