Question 1

The assignment method provides an optimum,one-to-one assignment of jobs to resources.

Accepted Answer

The assignment method is a mathematical technique that can provide an optimum, one-to-one assignment of jobs to resources.

Question 2

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 that aims to optimally assign tasks or jobs to available resources. This method involves maximizing the objective function (such as minimizing total cost or time) while satisfying a set of constraints (such as resource availability or job requirements). Other options such as overloading, computerized task determination, Gantt charts, or balancing scheduling do not fully capture the essence of the assignment method.

Question 5

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 (Constant Work-in-Process) cards provide a visual signal to limit the amount of work-in-process in a work center. By not allowing production to start until the current batch is finished, the work center can prevent overproduction, reduce lead times, and improve flow. MRP, Gantt charts, Johnson's rule, and the assignment method are not directly related to limiting work-in-process in a work center.

Question 9

There are two jobs to be assigned to two workers.The profit for worker A on job 1 is $5 and on job 2 is $8.The profit 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

Using the assignment method, we create a matrix with the profits for each worker on each job:

|   | Worker A | Worker B |
|---|---------|---------|
| 1 | $5      | $10     |
| 2 | $8     | $12      |

To find the best assignment, we need to identify the highest profits in each column and assign the corresponding workers to those jobs. In this case, the highest profit for job 1 is $10 (Worker B) and the highest profit for job 2 is $12 (Worker B again). Therefore, Worker B should be assigned to job 1 and Worker A should be assigned to job 2, giving us choice B as the best option.

Question 10

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

Accepted Answer

Gantt charts are useful for both scheduling and loading jobs. They help to visualize the timeframes and dependencies for each task, allowing for better planning and allocation of resources. Additionally, Gantt charts can be used to monitor progress and adjust schedules as needed.

Question 11

Question 12

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 a scheduling technique used to achieve an optimum, one-to-one matching of tasks and resources. It involves creating a matrix that lists the tasks and resources needed to complete them, and then assigning a score to each potential pairing based on factors like cost and availability. The algorithm then selects the pairings that result in the lowest overall cost or best use of resources. Johnson's rule, the CDS algorithm, the appointment method, and the reservation method are all scheduling techniques, but they are not specifically designed for one-to-one matching of tasks and resources.

Question 13

If an assignment problem consists of 6 workers and 7 projects:
A)one worker will not get a project assignment.
B)one worker will be assigned two projects.
C)each worker will contribute work toward the seventh project.
D)one project will not get a worker assigned.
E)The problem cannot be solved by assignment method.

Accepted Answer

Since there are only 6 workers and 7 projects, one project will not get a worker assigned. This means that the problem cannot be solved by the assignment method because there will always be an incomplete assignment.

Question 14

Question 15

The constant work-in-process (ConWIP)card aids input-output control by limiting the amount of work in a work center.

Accepted Answer

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

Question 16

A Gantt load chart shows the loading and idle time of several departments,machines,or facilities.

Accepted Answer

A Gantt load chart is a graphical representation that displays the loading and idle time of various departments, machines, or facilities over a certain period. It is commonly used in production planning and scheduling to ensure optimal resource utilization and avoid overloading or underutilization of resources.

Question 17

A work center had planned outputs of 10,15,13,and 20 hours with actual outputs of 12,14,13,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

Cumulative deviation = (Planned output - Actual output) for each unit of time
For 1st unit of time, planned output = 10 and actual output = 12
Cumulative deviation for 1st unit = (10-12) = -2
For 2nd unit of time, planned output = 15 and actual output = 14
Cumulative deviation for 2nd unit = (15-14) = 1
For 3rd unit of time, planned output = 13 and actual output = 13
Cumulative deviation for 3rd unit = (13-13) = 0
For 4th unit of time, planned output = 20 and actual output = 18
Cumulative deviation for 4th unit = (20-18) = 2
Total cumulative deviation = (-2+1+0+2) = 1
Therefore, the answer is (C) -1.

Question 18

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

This method is known as the ConWIP (Controlled Work-In-Process) system, which uses cards to limit the amount of work at a work center, control lead time, and monitor backlog. The use of ConWIP cards helps to maintain flow and reduce bottlenecks in the production process. Options A, B, C, and E are not the correct answer as they do not align with the described method.

Question 19

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 in scheduling, it is not a requirement. The key factors that must be known are the sequence of work, the time required for each item, the capacity of each work center, and the availability of each work center.

Question 20
