1 | | Scheduling is primarily concerned with the timing of operations. |
| | A) | True |
| | B) | False |
|
|
2 | | Job shop schedule by priority rules is inherently deterministic in nature; the scheduler must plan as if both the order of processing and the amount of time each job would take in each work center were known exactly. |
| | A) | True |
| | B) | False |
|
|
3 | | The assignment method will solve a wide variety of problems that have to do with flow systems. |
| | A) | True |
| | B) | False |
|
|
4 | | The hierarchy of decisions in production operations is, in order: (1) long-term capacity planning, (2) aggregate planning, (3) material requirements planning, (4) capacity requirements planning, (5) scheduling |
| | A) | True |
| | B) | False |
|
|
5 | | Johnson's rule, the assignment method, and loading and priority rules are all appropriate methods of scheduling for job shops. |
| | A) | True |
| | B) | False |
|
|
6 | | Which one of the following is not an appropriate job-shop scheduling rule? |
| | A) | Due date |
| | B) | Assignment method |
| | C) | First come first served |
| | D) | Shortest processing time |
| | E) | Johnson's rule |
|
|
7 | | Which one of the following is an optimizing technique? |
| | A) | Shortest processing time |
| | B) | Assignment method |
| | C) | First come first served |
| | D) | Loading |
| | E) | None of these |
|
|
8 | | A major disadvantage of the SPT rule is: |
| | A) | it tends to make long jobs wait. |
| | B) | it results in high in-process inventories. |
| | C) | long jobs tend to delay other jobs. |
| | D) | it does not take processing time into account. |
| | E) | none of these. |
|
|
9 | | Which statement is correct? |
| | A) | Vertical loading involves infinite loading. |
| | B) | Horizontal loading involves infinite loading. |
| | C) | Vertical loading involves finite loading. |
| | D) | a. and b. are correct. |
| | E) | b. and c. are correct. |
|
|
10 | | Finite loading, as compared to infinite loading, assumes that: |
| | A) | There are a finite number of jobs to be done. |
| | B) | Work centers can be loaded without regard to their capacity. |
| | C) | Work centers' capacity must be taken into account. |
| | D) | Work centers' capacity may be taken into account, but it's not required. |
| | E) | none of the above |
|
|
11 | | In a task assignment situation, in how many different ways can five jobs be assigned to five machines? |
| | A) | 1 |
| | B) | 5 |
| | C) | 25 |
| | D) | 120 |
| | E) | 3,125 |
