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 2 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

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

A. 0%

B. 10%

C. 25%

D. 33%

E. 50%

F. 66%

G. 75%

Suppose you are given the flowchart shown below (Task 5 requires input from both Task 2 and Task 4). There are no buffers between tasks. The numbers in parentheses reflect throughput capacities. Using this, answer the next 3 questions:

Task 1 (8) ------------> Task 2 (10) ------------| |------> Task 5 (18) -----------> Task 3 (15) ------------> Task 4 (9)-------------|

What is the actual throughput out of task 5?

A. Less than 8

B. 8

C. 9

D. 10

E. 15

F. 18

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

A. Task 1

B. Task 2

C. Task 3

D. Task 4

E. Task 5

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

A. Task 1

B. Task 2

C. Task 3

D. Task 4

E. Task 5
