Question 1

Which of the following helps organize work orders by tracking the parts for products and the status of jobs during their scheduling,production,and quality control phases?

Accepted Answer

A route sheet typically includes information on the parts required for each product, the steps involved in production, and the status of jobs during scheduling, production, and quality control phases. This helps to organize work orders and track the progress of each job. Pareto charts are used to analyze data and identify the most significant factors contributing to a problem. Assembly charts and assembly drawings provide visual representations of how products are assembled but do not track the status of jobs during production.

Question 2

The daily output required from an assembly line is 80 units.If the line operates 4 hours a day,what is the cycle time per unit?

Accepted Answer

The answer of The daily output required from an assembly...

Question 3

The daily output required from an assembly line is 600 units.If the line operates 12 hours a day,what is the cycle time per unit?

Accepted Answer

To find the cycle time per unit, divide the total operating time by the number of units required. Operating time is 12 hours, which is 720 minutes (12 hours * 60 minutes/hour). Dividing 720 minutes by 600 units gives 1.2 minutes per unit, which is 1 minute and 12 seconds.

Question 4

A technique that provides a dynamic view of a process using computers,multiple inputs,work centers,and processing techniques to help an operations manager look at the variability of a process under different conditions is known as ______.

Accepted Answer

A process simulation is a technique used by operations managers to create a dynamic view of a process using computers, multiple inputs, work centers, and processing techniques. The simulation enables the manager to observe the variability of the process under different conditions and make changes as necessary to improve efficiency and effectiveness. A value stream map, Pareto mapping, and assembly chart are all other techniques used in operations management but do not provide the dynamic view of a process that a process simulation does.

Question 5

The relationship between two or more tasks that requires certain tasks to be done before others is known as ______.

Accepted Answer

A precedence relationship refers to the relationship between tasks wherein certain tasks need to be completed before others can begin. This implies that some tasks have a higher precedence than others and cannot be started until their dependencies are satisfied.

Question 6

A graphic used to analyze and design the flow of materials and information across multiple processes is known as ______.

Accepted Answer

A value stream mapping (VSM) is specifically designed to analyze and design the flow of materials and information across multiple processes. This allows businesses to identify areas of waste and inefficiency and make improvements. Pareto charts, assembly charts, and assembly drawings may be useful in other contexts, but they are not specifically designed for this purpose.

Question 7

The measure of how well a process uses the time available to complete it is called ______.

Accepted Answer

Balance efficiency measures how effectively the available time is utilized in a process, indicating how well the process is balanced to minimize idle time and maximize productivity.

Question 8

The time required for the line to produce one unit to achieve an output rate that allows a firm to meet its demand requirements is known as ______.

Accepted Answer

Cycle time is the time required for the line to produce one unit. It is an important measure for manufacturers as it helps them evaluate their production capacity and efficiency. Flow time measures the time it takes for a unit to move from start to finish of the production process. Idle time measures the amount of time the line is not producing due to a variety of reasons, including maintenance or equipment breakdown. Balance efficiency measures how evenly work is distributed across a production line. While all of these measures are important for evaluating a production line, cycle time is the best choice for the given statement.

Question 9

A Muther's grid ______.

Accepted Answer

A Muther's grid is a visual representation of relationship rating in which symbols or letters represent the relationships between departments, aiding in the layout planning of facilities by showing the desired closeness of different departments based on their relationship strength.

Question 10

The sum of all task times in producing a product is 72 minutes.If the cycle time is 72 minutes,then the number of workstations required is ______.

Accepted Answer

The number of workstations required is determined by dividing the sum of all task times by the cycle time. Since both are 72 minutes, the result is 1, indicating only one workstation is needed.

Question 11

Line balancing refers to ______.

Accepted Answer

Line balancing is the process of assigning tasks to different workstations in a way that the time required to complete each task is approximately equal. This ensures that the production process is efficient and avoids bottlenecks or idle workers. Option A, C, and D are not correct definitions of line balancing.

Question 12

A service blueprint refers to ______.

Accepted Answer

A service blueprint is a tool used to analyze processes that have high service content by specifying how the service will be provided. It breaks down the service process into individual steps and identifies the different interactions and touchpoints between the customer and the service provider. This helps to identify potential problems in the service delivery process and improve overall service quality.

Question 13

The time required to completely produce an item if only one unit is being produced at a time is known as ______.

Accepted Answer

The time required to completely produce an item if only one unit is being produced at a time is known as flow time. Cycle time refers to the time required to complete one cycle of an operation, and idle time refers to time during which no production is taking place. Balance efficiency refers to how well work is balanced between different workers or machines.

Question 14

Which of the following is NOT true of a process chart?

Accepted Answer

A process chart does not typically show costs and points of indifference. It primarily focuses on illustrating the flow of activities or tasks in a process, including inputs, outputs, decision points and cross-functional relationships. Cost information may be included in some process charts, but it is not a defining feature.

Question 15

The difference between the total time available and the total time used to complete a process is known as ______.

Accepted Answer

The difference between the total time available and the total time used to complete a process is known as idle time. This refers to the time when the resources or machines are not being utilized or productive. Cycle time refers to the time it takes to complete a single process, while flow time refers to the time it takes a unit to go through the entire process. Balance efficiency refers to how well a process is balanced in terms of workload distribution.

Question 16

The sum of all task times in producing a product is 15 minutes.Eighty units need to be produced in 4 hours.What is the number of workstations required?

Accepted Answer

The total time required to produce 80 units is 80 * 15 = 1200 minutes. Since there are 4 hours or 240 minutes available, the number of workstations required is 1200 / 240 = 5.

Question 17

The daily output required from an assembly line is 120 units.If the line operates 8 hours a day,what is the cycle time per unit?

Accepted Answer

Cycle time per unit can be calculated by dividing the total available time by the daily output required.

Total available time = 8 hours = 480 minutes

Daily output required = 120 units

Cycle time per unit = Total available time / Daily output required

Cycle time per unit = 480 minutes / 120 units

Cycle time per unit = 4 minutes

Question 18

A technique developed by Richard Muther used to design new layouts or change old ones based on qualitative criteria is known as ______.

Accepted Answer

Richard Muther developed the "relationship rating" technique, which is used to design or modify layouts based on qualitative criteria, often represented in a relationship chart or diagram.

Question 19

The daily output required from an assembly line is 300 units.If the line operates 5 hours a day,what is the cycle time per unit?

Accepted Answer

The formula to calculate cycle time is: 
Cycle time = Operating time available / Daily output required 
In this case, operating time available is 5 hours (since the line operates for 5 hours a day) and daily output required is 300 units. 
Substituting these values in the formula: 
Cycle time = 5 hours * 60 minutes per hour / 300 units 
Cycle time = 1 minute per unit 
Therefore, the cycle time per unit is 1 minute. Option C is the correct choice.

Question 20

Idle time is computed by using which formula?

Accepted Answer

Idle time refers to the time when a resource is not actively being used. Therefore, idle time is computed by subtracting the total time used from the total time available, giving us the formula Total time available - Total time used. Choice C is the only option that matches this formula.
