solution

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

Task 1 (3) —> Task 2 (4) —> Task 3 (2) —> Task 4 (10).

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

i. What is the actual throughput rate out of task 4 in units per minute?

1. Less than 1
2. Greater than or equal to 1 but less than 2
3. Greater than or equal to 2 but less than 3
4. Greater than or equal to 3 but less than 4
5. Greater than or equal to 4 but less than 5
6. Greater than or equal to 5

Refer to Scenario :

ii. What is the utilization for task 1?

1. 0%
2. Greater than 0% but less than 10%
3. Greater than or equal to 10% but less than 25%
4. Greater than or equal to 25% but less than 50%
5. Greater than or equal to 50% but less than 75%
6. Greater than or equal to 75% but less than 100%
7. 100%

Suppose you have a two-activity sequential process: Task 1 —> Task 2.

Task 1 has a throughput capacity of 10 units per hour; task 2 has a throughput capacity of 15 units per hour. There are no inventory buffers between tasks.

iii. Which of the following would be true?

1. Task 1 would encounter blocking
2. Task 2 would encounter blocking
3. Task 1 would encounter starvation
4. Task 2 would encounter starvation
