Question 1

A straight-line flow pattern is considered a good layout design for back-office service operations.

Accepted Answer

A straight-line flow pattern allows for a clear and direct flow of work in back-office service operations, which can increase efficiency and reduce errors.

Question 2

A manufacturing cell groups the same or similar machines into cells to work on products that have dissimilar shapes and dissimilar processing requirements.

Accepted Answer

A manufacturing cell groups machines based on the products they produce, focusing on similar shapes and processing requirements to improve efficiency and reduce movement.

Question 3

Using the assembly-line balancing procedure, which of the following is the required cycle time if the production time in minutes per day is 1,440 and the required output per day in units is 2000?

Accepted Answer

The required cycle time is calculated by dividing the production time per day by the required output per day. Therefore, 1440 minutes / 2000 units = 0.72 minutes per unit.

Question 4

Having a lot of interstage storage of materials is considered a good layout design for a manufacturing plant.

Accepted Answer

Having a lot of interstage storage of materials can increase inventory levels and lead to waste, which is not considered a good layout design for a manufacturing plant. A lean manufacturing approach aims to minimize inventory and maximize efficiency.

Question 5

Which of the following is not considered an input to the layout decision in facility layout analysis?

Accepted Answer

Cost per square foot of alternative facilities is not directly related to the layout decision. It may be a consideration in choosing the location for the facility, but not in designing the layout itself. The other options are all important inputs to the layout decision.

Question 6

As a general rule, manufacturing workstations should not be very close together.

Accepted Answer

Workstations in manufacturing are often placed close together to improve workflow efficiency, reduce movement time, and facilitate communication among workers.

Question 7

Which of the following basic types of production layout formats is one that has similar equipment or functions are grouped together?

Accepted Answer

The workcenter layout groups equipment or functions with similar processing requirements. A production line layout arranges the workflow in a linear sequence, while an assembly line layout organizes tasks in a specific order. A group technology layout clusters items with similar characteristics or processing requirements, while a manufacturing cell layout groups together different machines to perform a specific set of tasks.

Question 8

Which of the following basic types of production layout formats is one in which equipment or work processes are arranged according to the progressive steps by which the product is made?

Accepted Answer

The assembly line layout is a production layout where equipment and work processes are arranged in a sequence of progressive steps by which the product is made. This type of layout increases efficiency and reduces waste by minimizing the movement of materials and workers throughout the production process.

Question 9

Using the assembly-line balancing procedure, which of the following is the required cycle time in minutes per unit if the daily production time is 480 minutes and the required daily output is 50 units?

Accepted Answer

The formula to find cycle time is:
Cycle Time = Production Time Available / Required Daily Output
Substituting the given values:
Cycle Time = 480 minutes / 50 units
Cycle Time = 9.6 minutes per unit. Therefore, the correct answer is (C) 9.6.

Question 10

Using the assembly-line balancing procedure, which of the following is the theoretical minimum number of workstations if the task times for the eight tasks that make up the job are 7, 4, 7, 8, 9, 4, 3, and 6 minutes, and the cycle time is 8 minutes?

Accepted Answer

To use the assembly-line balancing procedure, we need to calculate the theoretical minimum number of workstations required based on the task times and the cycle time.

Step 1: Calculate the sum of task times 
7 + 4 + 7 + 8 + 9 + 4 + 3 + 6 = 48

Step 2: Calculate the minimum number of workstations 
Minimum number of workstations = Total task time / Cycle time 
Minimum number of workstations = 48 / 8 
Minimum number of workstations = 6

Therefore, the theoretical minimum number of workstations required is 6. Choice C is the correct answer.

Question 11

Which of the following is not a basic type of production layout format?

Accepted Answer

The answer of Which of the following is not a...

Question 12

The objective of a retail service layout is to maximize net profit per square foot of store space.

Accepted Answer

The main objective of a retail service layout is to optimize the use of space and create an environment that encourages customers to make purchases, ultimately leading to increased revenue and net profit per square foot of store space.

Question 13

In a good layout design for a manufacturing facility, it is acceptable to have backtracking by personnel in the delivery of a customer's product.

Accepted Answer

Backtracking by personnel should be minimized or eliminated in a good layout design for a manufacturing facility. It can cause unnecessary delays, waste time and resources, and potentially increase the risk of errors or accidents.

Question 14

You have just determined the actual number of workstations that will be used on an assembly line to be 6 using the assembly-line balancing procedure.The cycle time of the line is 5 minutes, and the sum of all that tasks required on the line is 25 minutes.Which of the following is the correct value for the resulting line's efficiency?

Accepted Answer

The efficiency of an assembly line is calculated as the sum of task times divided by the product of the number of workstations and the cycle time. Here, efficiency = 25 / (6 * 5) = 0.833.

Question 15

Which of the following is a basic type of production layout format?

Accepted Answer

Manufacturing cell is a basic type of production layout format that involves grouping machines together by the product or product family they produce, creating a self-contained unit for the production of that product or family. This approach can lead to increased efficiency and reduced material handling time. The other options listed are not basic types of production layout formats.

Question 16

A project layout is characterized by a relatively low number of production units in comparison with workcenter and assembly-line formats.

Accepted Answer

A project layout is designed for the production of unique or customized products and involves a low volume of production units, often involving a team of skilled workers who work on specific tasks. This layout is different from workcenter and assembly-line formats, which typically involve a higher volume of production units and a more repetitive production process.

Question 17

Assembly-line balancing means assigning all necessary tasks to a series of workstations so that each workstation has no more than can be done in the workstation cycle time and so that idle time across all workstations is minimized.

Accepted Answer

Assembly-line balancing is the process of optimizing workstations in a production line by assigning tasks to each station to achieve maximum efficiency and minimize idle time.

Question 18

Using the assembly-line balancing procedure, which of the following is the theoretical minimum number of workstations if the task times for the six tasks that make up the job are 4, 6, 7, 2, 6, and 5 minutes, and the cycle time is 10 minutes?

Accepted Answer

The theoretical minimum number of workstations is calculated by dividing the total task time by the cycle time. The total task time is 4 + 6 + 7 + 2 + 6 + 5 = 30 minutes. Dividing 30 by the cycle time of 10 minutes gives 3 workstations.

Question 19

A project layout is characterized by a high degree of task ordering.

Accepted Answer

A project layout involves highly ordered tasks, with each task typically following a sequential path. This is important in ensuring efficient and timely completion of the project, as well as ensuring that each task is completed before moving on to the next.

Question 20

The objective of a mixed-model line layout is to meet the demand for a variety of products and avoid building high inventories.

Accepted Answer

A mixed-model line layout is designed to allow for the production of a variety of products on the same production line, thereby reducing the need for building up high levels of inventory for each individual product. Instead, the line is set up to efficiently produce the required amount of each product as needed, reducing the overall inventory levels and meeting demand for a variety of products.
