Business Quiz: Planning And Manufacturing

1.

A work center consists of two machines working eight hours a day and five days a week. Historically, utilization has been 80%, and efficiency and has been 90%. To the nearest hour, what is the rated capacity?
- A.
  
  80 hours
- B.
  
  58 hours
- C.
  
  40 hours
- D.
  
  30 hours
Correct Answer
B. 58 hours

Explanation
The rated capacity can be calculated by multiplying the number of machines, the number of hours they work per day, and the number of days they work per week. In this case, there are two machines working eight hours a day and five days a week, so the rated capacity is 2 machines * 8 hours/day * 5 days/week = 80 hours.

What term indicates the percentage of time the work center is active compared to the available time?
- A.
  
  Efficiency
- B.
  
  Effectiveness
- C.
  
  Utilization
- D.
  
  Uptime
Correct Answer
C. Utilization

Explanation
Utilization is the correct answer because it refers to the percentage of time that a work center is actively used compared to the total available time. It measures how efficiently the work center is being utilized and indicates the productivity and efficiency of the operations. Utilization takes into account both the productive and non-productive time, providing a comprehensive measure of how effectively the work center is being utilized.

What term is used for the ratio of standard hours of work produced to hours actually worked?
- A.
  
  Efficiency
- B.
  
  Effectiveness
- C.
  
  Utilization
- D.
  
  Uptime
Correct Answer
A. Efficiency

Explanation
Efficiency is the correct answer because it refers to the ratio of standard hours of work produced to the actual hours worked. It measures how well resources are utilized to complete a task or achieve a goal. A high efficiency indicates that the work is being done in a timely and productive manner, while a low efficiency suggests that there is a waste of resources or inefficiencies in the process.

4.

What term is used for calculating (available time) x (utilization) x (efficiency)?
- A.
  
  Effectiveness
- B.
  
  Useful capacity
- C.
  
  Demonstrated capacity
- D.
  
  Rated capacity
Correct Answer
D. Rated capacity

Explanation
Rated capacity refers to the maximum output that a system or process can achieve under ideal conditions. It is calculated by multiplying the available time, utilization (percentage of time the system is used), and efficiency (percentage of rated capacity achieved). This calculation helps in determining the maximum potential output of a system or process.

Rate this question:
5.

Which of the following shows the capacity required at each work center based on planned and release orders for each time period of the plan?
- A.
  
  Work center profile
- B.
  
  Load profile
- C.
  
  Scheduled order profile
- D.
  
  Work-to-be-done report
Correct Answer
B. Load profile

Explanation
A load profile shows the capacity required at each work center based on planned and release orders for each time period of the plan. It provides a detailed breakdown of the workload at each work center, allowing for better capacity planning and resource allocation. The load profile helps in identifying potential bottlenecks and optimizing the production schedule to ensure efficient utilization of resources.

Which of the following must production activity control do when planning the flow of work?
- A.
  
  Be sure the material and tooling needed are available
- B.
  
  Advise the plant supervisor of future orders
- C.
  
  Refer to the production plan for what orders to run
- D.
  
  Complete a materials requisition plan
Correct Answer
A. Be sure the material and tooling needed are available

Explanation
Production activity control must ensure that the material and tooling needed for the work are available. This is crucial for a smooth flow of work as without the necessary materials and tools, production cannot proceed efficiently. By ensuring availability, production activity control can prevent delays and interruptions in the production process, allowing for timely completion of orders.

Which of the following is concerned with very short-term detailed planning of the flow of orders through manufacturing?
- A.
  
  Production planning
- B.
  
  Master production scheduling
- C.
  
  Material requirements planning
- D.
  
  Production activity control
Correct Answer
D. Production activity control

Explanation
Production activity control is concerned with very short-term detailed planning of the flow of orders through manufacturing. This involves monitoring and controlling the production activities on a day-to-day basis to ensure that orders are being processed efficiently and according to the schedule. It involves tasks such as assigning work to specific machines or workstations, tracking the progress of orders, and making adjustments to the production schedule as needed. Production activity control plays a crucial role in maintaining smooth operations and meeting customer demand in a timely manner.

Which of the following is an element of manufacturing lead time?
- A.
  
  Design time
- B.
  
  Delivery lead time
- C.
  
  Wait time
- D.
  
  Purchase lead time
Correct Answer
C. Wait time

Explanation
Wait time is an element of manufacturing lead time because it refers to the amount of time a product spends waiting in between different stages of the manufacturing process. This can include waiting for materials or components to arrive, waiting for machines or equipment to become available, or waiting for quality control checks to be completed. Minimizing wait time is important in order to increase efficiency and reduce overall lead time, ensuring that products are manufactured and delivered to customers in a timely manner.

What is the name given to a scheduling system in which the last operation on a routing is scheduled first and for completion on the due date?
- A.
  
  Forward scheduling
- B.
  
  Backward scheduling
- C.
  
  Infinite scheduling
- D.
  
  Finite scheduling
Correct Answer
B. Backward scheduling

Explanation
Backward scheduling is the name given to a scheduling system where the last operation on a routing is scheduled first and for completion on the due date. This approach allows for better coordination and planning as it ensures that all preceding operations are completed in a timely manner to meet the final deadline. By working backwards from the due date, it helps to prioritize tasks and allocate resources efficiently, ultimately improving the overall efficiency and on-time delivery of projects.

Which of the folliwng statements is most accurate?
- A.
  
  Work centers located after a bottleneck should work at full capacity
- B.
  
  A time buffer should be established after a bottleneck
- C.
  
  Work centers feeding a bottleneck should work at full capacity
- D.
  
  A bottleneck will control the throughput of all products processed by it
Correct Answer
D. A bottleneck will control the throughput of all products processed by it

Explanation
A bottleneck in a production process refers to a point where the capacity of the system is limited, causing a slowdown in the overall throughput. This means that the bottleneck will determine the maximum rate at which products can be processed. As a result, the statement "A bottleneck will control the throughput of all products processed by it" is the most accurate. The other options, such as work centers working at full capacity or establishing a time buffer after a bottleneck, may be strategies to manage or mitigate the impact of a bottleneck, but they do not directly address the control of throughput by the bottleneck itself.
