Question 1

What is a scheduling technique used to achieve an optimum, one-to-one matching of tasks and resources?
A) the assignment method
B) Johnson's rule
C) the CDS algorithm
D) the appointment method
E) the reservation method

Accepted Answer

The assignment method is specifically designed to achieve an optimum, one-to-one matching of tasks and resources, making it the best choice for this scenario. Johnson's rule, the CDS algorithm, the appointment method, and the reservation method do not have this specific goal in mind.

Question 2

One of the major limitations of the Gantt load chart is that it doesn't account for production variability such as unexpected breakdowns or human errors.

Accepted Answer

The Gantt load chart only considers scheduled tasks and assumes that they will be completed on time without any disruptions. It doesn't account for unforeseen events such as machine breakdowns, employee absenteeism, or material shortages that can affect production efficiency and output. Therefore, it is not an accurate tool for planning and scheduling in complex production environments.

Question 3

Accepted Answer

The answer of Compare short-term scheduling at process-focused, repetitive, and...

Question 4

Accepted Answer

The ConWIP card is used to limit the amount of work in a work center, which helps with input-output control.

Question 5

Accepted Answer

The answer of In the sequence of decisions that affect...

Question 9

Gantt charts are useful for scheduling jobs, but not for loading them.

Accepted Answer

Gantt charts can be helpful in both scheduling and loading jobs. They provide a visual representation of tasks and their timeline, allowing for easy identification of overlapping or conflicting schedules. Additionally, Gantt charts can help with resource allocation, allowing for efficient utilization of available resources.

Question 10

A work center had actual input of 280 hours and actual output of 290 hours. What is the change in backlog?
A) 10
B) -10
C) 0
D) 1.037
E) Unable to determine with the given information

Accepted Answer

Backlog = Actual Input - Actual Output
Backlog = 280 - 290
Backlog = -10, which means there is a decrease in backlog by 10 hours. Hence, the correct answer is B.

Question 11

There are two jobs to be assigned to two workers. The cost for worker A on job 1 is $5 and on job 2 is $8. The cost for worker B on job 1 is $10 and on job 2 is $12. How should the work be divided using the assignment method?
A) worker A assigned to job 1 and worker B assigned to job 2
B) worker A assigned to job 2 and worker B assigned to job 1
C) worker A gets both jobs 1 and 2
D) worker B gets both jobs 1 and 2
E) unable to determine

Accepted Answer

The assignment method aims to minimize the total cost. Worker A assigned to job 1 ($5) and worker B to job 2 ($12) results in the lowest combined cost of $17.

Question 12

________ scheduling begins with the due date and schedules the final operation first and the other job steps in reverse order.

Accepted Answer

The answer of ________ scheduling begins with the due date...

Question 13

A work center had planned outputs of 10, 15, 13, and 20 hours with actual outputs of 12, 14, 15, and 18 hours. What is the cumulative deviation in output?
A) 0
B) 1
C) −1
D) 58
E) Unable to determine with the given information

Accepted Answer

The answer of A work center had planned outputs of...

Question 14

The assignment method is:
A) a method to highlight overloads in a given work center.
B) a computerized method of determining appropriate tasks for an operation.
C) a form of linear programming for optimally assigning tasks or jobs to resources.
D) the same thing as the Gantt schedule chart.
E) a method for achieving a balance between forward and backward scheduling.

Accepted Answer

The assignment method is a form of linear programming used to optimally assign tasks or jobs to resources. It involves identifying the objective, constraints, and decision variables, and then using mathematical algorithms to find the optimal solution. This method is often used in operations management to optimize production schedules and minimize costs. Choices A, B, D, and E are not accurate definitions of the assignment method.

Question 15

If job 5 takes 3, 4, or 6 hours to be completed by workers A, B, and C, respectively, what would the row values for job 5 be after performing Step 1A of the assignment method?
A) 0, 1, 3
B) 8, 9, 11
C) 0, 1, 2
D) 6, 7, 9
E) 1, 4/3, 1/2

Accepted Answer

Step 1A of the assignment method involves subtracting the smallest number in each row from all the numbers in that row. For job 5, the smallest time is 3 hours (by worker A), so we subtract 3 from each of the times: 3-3=0, 4-3=1, 6-3=3.

Question 16

Which of the following is NOT required to be known in order to schedule process-focused facilities?
A) the sequence of work
B) which workers are assigned to each work center
C) the time required for each item
D) the capacity of each work center
E) the availability of each work center

Accepted Answer

While knowing which workers are assigned to each work center can be helpful information, it is not necessary for scheduling process-focused facilities. The other options listed are all crucial pieces of information needed for effective scheduling.

Question 17

A work center is interested in limiting work-in-process by not allowing production to start again until the current batch is finished. The best solution most likely involves:
A) MRP.
B) ConWIP cards.
C) Gantt charts.
D) Johnson's rule.
E) the assignment method.

Accepted Answer

ConWIP cards are a tool used in the Kanban system for controlling and limiting work-in-process. They ensure that production does not start again until the current batch is finished by visually indicating when a certain amount of WIP has been reached and signaling the need for replenishment before the next batch can be started. MRP, Gantt charts, Johnson's rule, and the assignment method are not specifically designed to limit WIP in this way.

Question 18

________ is the assignment of jobs to work or processing centers.

Accepted Answer

The answer of ________ is the assignment of jobs to...

Question 19

What is a method of input-output control that uses a system of cards to limit the amount of work at a work center and also to control lead time and monitor backlog?
A) the assignment method
B) backward scheduling
C) forward scheduling
D) ConWIP cards
E) level material use

Accepted Answer

ConWIP (Constant Work In Process) cards are a method of input-output control that limit the amount of work at a work center and also control lead time and monitor backlog. ConWIP cards are used in production lines and are posted at each workstation to indicate the maximum number of parts that the station can hold at any given time. When an operator at a workstation begins producing parts, he or she moves one of the ConWIP cards from the "not started" column to the "in progress" column. This signals to the upstream workstations that they may begin producing more parts, and to the downstream workstations that they should prepare for more parts coming their way. This helps to prevent overproduction and reduce lead times.

Question 20

Which of the following is an aid used to monitor jobs in progress?
A) a Gantt load chart
B) the assignment method
C) a Gantt schedule chart
D) Johnson's rule
E) a Gantt progress chart

Accepted Answer

A Gantt schedule chart is specifically designed to monitor the progress of jobs, showing the start and finish times of each task in a project.
