Question 1

Which of the following is not one of the major functions of shop-floor control?
A)Measure efficiency, utilization, and productivity of manpower and machines
B)Assign a priority to each shop order
C)Load machine hours into work stations
D)Track WIP quantity by location by shop order to accounting
E)Convey shop order status information to the office

Accepted Answer

The major functions of shop-floor control include measuring efficiency, assigning priority to shop orders, tracking WIP quantity, and conveying order status information to the office. Loading machine hours into work stations is a task typically handled by production planning and scheduling.

Question 2

Assume you are sequencing jobs using Johnson's rule.A particular job requires 3 hours to assemble and then is followed by 2 hours in the painting department.Which of the following is where you would schedule this job?
A)As early as possible in the unfilled job sequence
B)As late as possible in the unfilled job sequence
C)The schedule would depend on the due date
D)Does not matter
E)Johnson's rule does not apply

Accepted Answer

Johnson's rule states that the jobs should be scheduled in such a way that the total idle time between the two departments is minimized. Since the particular job requires more time in the painting department, it should be scheduled as late as possible in the unfilled job sequence to minimize the idle time between assembly and painting.

Question 3

Which of the following is one of the major functions of shop-floor control?
A)Observing the priorities set for each shop order
B)Keeping work-in-process inventory out of the way
C)Conveying shop-order status information to the office
D)Controlling cost and materials waste
E)Keeping the workforce fully utilized

Accepted Answer

One of the major functions of shop-floor control is conveying shop-order status information to the office, allowing for coordination and adjustment of production schedules as needed. While the other choices (observing priorities, keeping inventory out of the way, controlling costs and waste, and maximizing workforce utilization) are also important functions of shop-floor control, they do not necessarily qualify as major functions.

Question 4

Assume there are five jobs (i.e., A, B, C, D and E) that need to be sequenced in a production schedule.The remaining operating time necessary for completion of job A is 3 days (i.e., job A will take 3 more days to complete), B will take 9 days, C will take 6 days, D will take 5 days and E will take 8 days.Which job should be scheduled last if using the SOT priority rule for job sequencing?
A)A
B)B

A)Last come first served
B)Last complaint first
C)First on hand first
D)Longest slack time first
E)Parts on hand first

Accepted Answer

Question 7

A job has 5 days of processing time left to do before completion and today is the 10th day of the month.If the job is due on the 14th day of the month, what is its critical ratio?
A)5
B)2
C)0.8
D)0.5
E)0.1

Accepted Answer

The critical ratio is calculated by dividing the time left to complete the job by the time left until the due date. In this case, the time left to complete the job is 5 days and the time left until the due date is 4 days (14th day of the month minus the 10th day of the month). Therefore, the critical ratio is 5/4 which equals 1.25. However, since the critical ratio is a measure of how much time is left relative to how much time is needed, it cannot be greater than 1. So, the critical ratio is actually 0.8 (5/4 = 1.25, but 1.25 is greater than 1, so the critical ratio is 0.8). The best choice is C.

Question 8

Assume you are sequencing jobs using Johnson's rule.A particular job requires 7 hours to assemble and then is followed by 8 hours in the painting department.Which of the following is where you would schedule this job?
A)As early as possible in the unfilled job sequence
B)As late as possible in the unfilled job sequence
C)The schedule would depend on the due date
D)Does not matter
E)Johnson's Rule does not apply

Accepted Answer

Johnson's rule is used for minimizing the total time taken to complete a set of jobs that are to go through two stages of production. The rule states that if a job has a shorter first operation, it should be scheduled as early as possible, and if it has a shorter second operation, it should be scheduled as late as possible. Since the given job requires 7 hours to assemble (first operation) and then 8 hours in the painting department (second operation), it has a shorter first operation and thus should be scheduled as early as possible in the unfilled job sequence.

Question 9

The assignment method is useful in solving scheduling problems that have which of the following characteristics?
A)There are "n" jobs to be distributed to "n" machines or workers
B)Each job can only be done on one particular machine
C)Speed and efficiency are important
D)The objective is to minimize cost and lateness of delivery
E)The jobs have to go through more than one process

Accepted Answer

The answer of The assignment method is useful in solving...

Question 10

Assume there are five jobs (i.e., A, B, C, D and E) that need to be sequenced in a production schedule.The remaining operating time necessary for completion of job A is 4 days (i.e., job A will take 4 more days to complete), B will take 7 days, C will take 8 days, D will take 2 days, and E will take 5 days, which job should be scheduled first if you use the SOT priority rule for job sequencing?
A)A
B)B
C)C
D)D
E)E

Accepted Answer

The SOT (shortest operating time) priority rule means that the job with the shortest remaining operating time should be scheduled first. Based on this rule, job D should be scheduled first because it has the shortest remaining operating time of only 2 days.

Question 11

Which of the following is not a priority rule used to schedule the sequence of jobs in a production operation?
A)First-come-first served
B)Shortest operating time
C)Last-in-first-out
D)Critical ratio
E)Slack-time-remaining per operation

Accepted Answer

First-come-first-served, shortest operating time, critical ratio, and slack-time-remaining per operation are all priority rules used to schedule the sequence of jobs in a production operation. However, last-in-first-out is not a priority rule commonly used in production operations. LIFO is an inventory accounting method, not a scheduling priority rule.

Question 12

Which of the following is a principle of work center scheduling?
A)Once started a job can and should be finished even if unavoidably interrupted
B)Reschedule every day
C)Achieve certainty in standards and routings
D)Give work centers less to do then their maximum
E)Assign the first worker to all of the days that require staffing

Accepted Answer

The principle of work center scheduling is to reschedule every day based on the latest information, such as updated job statuses, resource availability, and new orders. This helps to ensure that the production process remains efficient and flexible, and that the work centers are utilized optimally. A is not correct because it may lead to unnecessary waiting times and reduce the overall productivity. C is not correct because achieving certainty in standards and routings is important but not the main principle of work center scheduling. D is not correct because giving work centers less to do than their maximum may lead to underutilization of resources. E is not correct because assigning the first worker to all of the days that require staffing is not a principle of work center scheduling.

Question 13

Which of the following priority rules used in scheduling the sequence of production is calculated as the slack time remaining in the schedule divided by the number of remaining operations, with the smallest value being run first?
A)STR
B)Johnson's
C)STR/OP
D)LCFS
E)FCFS

Accepted Answer

The priority rule calculated as slack time remaining in the schedule divided by the number of remaining operations is STR/OP (Slack Time Remaining divided by Operations Remaining) which is the best choice for scheduling production.

Question 14

Assume there are five jobs (i.e., A, B, C, D and E) that need to be sequenced in a production schedule.The remaining operating time necessary for completion of job A is 3 days (i.e., job A will take 3 more days to complete), B will take 9 days, C will take 6 days, D will take 5 days and E will take 8 days.In what order will these jobs be scheduled if using the SOT priority rule for job sequencing?
A)A-B-D-E-C
B)A-D-C-E-B
C)D-C-A-B-E
D)B-E-C-D-A
E)E-D-A-B-C
