Question 1

Which one of the following is NOT common to repetitive and product-oriented layouts?

Accepted Answer

Repetitive and product-oriented layouts are designed for high volume and standardized output, which makes them less flexible and responsive to changes in demand. Therefore, the ability to adjust to changes in demand is not a common characteristic of these layouts.

Question 2

The assumptions necessary for a successful product-oriented layout include all EXCEPT which of the following?

Accepted Answer

The other assumptions (A, B, and D) are necessary for a successful product-oriented layout. However, volatile product demand can make it difficult to efficiently use equipment and raw materials, causing delays and reducing productivity.

Question 3

In assembly-line balancing,the theoretical minimum number of workstations is:

Accepted Answer

The theoretical minimum number of workstations is calculated by dividing the sum of all task times by the cycle time (A), rounding up to the next integer if it's a fraction (B), and it may not always be possible to achieve this minimum due to task assignment constraints (C).

Question 4

Cycle time is computed as:

Accepted Answer

Cycle time is calculated as the daily operating time divided by the scheduled output, which is how long each operation in the process takes to complete in order to meet the day's production goals.

Question 5

If the schedule calls for the production of 120 units per day and 480 minutes of production time are available per day,the cycle time would be 4 minutes.

Accepted Answer

Cycle time can be calculated by dividing the available production time by the number of units required to be produced.

Cycle time = Available production time / Number of units required to be produced

In this case,

Cycle time = 480 minutes / 120 units = 4 minutes

Therefore, the statement is true.

Question 6

A production line is to be designed for a job with four tasks.The task times are 2.4 minutes,1.4 minutes,0.9 minutes,and 1.7 minutes.After line balancing,the largest possible assigned cycle time is ________ minutes,and the smallest possible assigned cycle time is ________ minutes.

Accepted Answer

The answer of A production line is to be designed...

Question 7

A production line is to be designed to make 500 El-More dolls per day.Each doll requires 11 activities totaling 16 minutes of work.The factory operates 750 minutes per day.What is the required cycle time for this assembly line?

Accepted Answer

The answer of A production line is to be designed...

Question 8

A production line is to be designed for a product whose completion requires 21 minutes of work.The factory works 400 minutes per day.Can an assembly line with five workstations make 100 units per day?

Accepted Answer

To produce 100 units per day, each unit must be completed in 4 minutes (400 minutes / 100 units). With 21 minutes of work required per unit, even with a perfectly balanced line, each of the five workstations would need to work for 4.2 minutes per unit (21 minutes / 5 workstations), which exceeds the 4-minute requirement. Therefore, it's not possible to meet the target with five workstations.

Question 9

Product-oriented layouts tend to have high levels of work-in-process inventories.

Accepted Answer

The answer of Product-oriented layouts tend to have high levels...

Question 10

One drawback of a product-oriented layout is that work stoppage at any one point ties up the whole operation.

Accepted Answer

In a product-oriented layout, each workstation is specialized to perform a specific task in the production process. Therefore, if one workstation experiences a work stoppage, it can impact the entire production process and result in a delay in the completion of the final product.

Question 11

Which of the following is TRUE regarding fabrication lines?

Accepted Answer

The answer of Which of the following is TRUE regarding...

Question 12

A product-oriented layout would be MOST appropriate for which one of the following businesses?

Accepted Answer

A product-oriented layout is best suited for businesses that involve heavy manufacturing or processing, such as steel making. This layout focuses on the efficient flow of materials and resources to produce a specific product, rather than accommodating customer traffic or service. Fast food and grocery stores, on the other hand, may use a combination of different layout types to facilitate customer service and product display. Insurance sales and clothing alterations typically do not rely heavily on physical product production, making a product-oriented layout less necessary.

Question 13

Cycle time is the maximum time that the product is allowed at each workstation.

Accepted Answer

Cycle time is the maximum time that the product is allowed at each workstation, so the statement is true.

Question 14

Which of the following is one of the main advantages of a product-oriented layout?

Accepted Answer

One of the main advantages of a product-oriented layout is that it typically results in lower variable cost per unit, as the focused and efficient production process allows for economies of scale.

Question 15

Which of the following is a disadvantage of product-oriented layout?

Accepted Answer

All of the options listed are disadvantages of product-oriented layouts. These types of layouts are designed to produce high volumes of a specific product, which can lead to inflexibility in handling different products or production rates. Additionally, any work stoppage can disrupt the entire operation and the large investment required to establish the process can make it difficult to adapt to changes in demand or market conditions.

Question 16

In a product-oriented layout,what is the process of deciding how to assign tasks to workstations?

Accepted Answer

The process of deciding how to assign tasks to workstations in a product-oriented layout is called assembly-line balancing. This involves determining the optimal sequence of tasks and the number of workstations needed to complete the production process efficiently. This is different from station balancing (A), which involves assigning tasks to specific workstations already determined by the assembly line layout. Process balancing (B) and task allocation (C) are not specific to product-oriented layouts and may refer to a variety of different production systems. Work allocation (E) is a general term that could be used in different contexts but does not specifically refer to product-oriented layouts.

Question 17

In assembly-line balancing,cycle time (the ratio of available production time to scheduled production)is the:

Accepted Answer

Cycle time is the maximum time that a product is allowed at each workstation in assembly-line balancing. It determines the rate at which the workstations must operate to meet the production demand. The other options do not accurately describe cycle time.

Question 18

Heuristics are problem-solving procedures that mathematically optimize the solution.

Accepted Answer

Heuristics are problem-solving procedures that may not find the optimal solution, but rather find a satisfactory solution in a reasonable amount of time.

Question 19

The central problem in product-oriented layout planning is:

Accepted Answer

The central problem in product-oriented layout planning is minimizing the imbalance in workloads among workstations. This is important for efficient and effective production processes.

Question 20

Four hundred and eighty minutes of production time are available per day.Scheduled production is 120 units per day.What is the required cycle time?

Accepted Answer

Cycle time = Total production time available / Scheduled production= 480 minutes / 120 units= 4 minutes
