Question 1

The Gantt layout chart shows the job schedule at each facility and the state of completion of all jobs.

Accepted Answer

The Gantt chart displays the job schedule and progress of each job at a facility.

Question 2

Small benefits in highly repetitive environments can add up to a substantial cash savings or profit accumulation.

Accepted Answer

Small benefits in highly repetitive environments can add up over time, resulting in increased efficiency and potentially substantial cash savings or profit accumulation. For example, small improvements in a manufacturing process that save a few seconds per unit can add up to significant time and cost savings over the course of producing thousands or millions of units. Similarly, small changes in a customer service process that reduce call times by a few seconds or increase upsell rates by a small percentage can lead to higher customer satisfaction and increased revenue over time.

Question 3

When there are many jobs and facilities,sequencing rules have diminishing economic importance.

Accepted Answer

Sequencing rules become more important with more jobs and facilities as they help in optimizing the order of operations, reducing wait times, and improving overall efficiency.

Question 4

Shop loading is required to assign specific jobs or teams to specific facilities.

Accepted Answer

Shop loading is the process of assigning specific jobs or teams to particular facilities or workstations. This helps to ensure that the right people are in the right place, with the right equipment and tools, to complete the required tasks efficiently and effectively. Without shop loading, there can be confusion and inefficiencies in the production process, leading to delays, rework, and extra costs.

Question 5

Bottlenecks need to be taken into account,and the goal of synchronized manufacturing requires coordination of the entire job shop with respect to the mix of jobs that is being orchestrated.

Accepted Answer

The statement expresses the importance of considering bottlenecks and coordinating the entire job shop for synchronized manufacturing, which is true.

Question 6

Variability of the order mix is a factor in planning capacity which requires taking corrective actions during aggregate scheduling.

Accepted Answer

Variability in the order mix can lead to fluctuations in demand, which can impact capacity planning. Adjustments may need to be made in aggregate scheduling to handle this variability and ensure that capacity requirements are met.

Question 7

Shifting of job requirements can lead to an unbalanced load among departments which often happens after decisions have been made which tend to be irreversible.

Accepted Answer

Shifting of job requirements can disrupt the balance within departments which could lead to an unbalanced workload for some departments. This is often a result of decisions that have already been made and cannot be easily reversed.

Question 8

Often the revenue is rⱼ because it is a function of the job,j,and not the machine,i.

Accepted Answer

The statement is true. The revenue generated depends on the job and not on the machine used to complete the job.

Question 9

The assignment model provides solutions when jobs compete for facilities and where it is desirable to split some job assignments.

Accepted Answer

The assignment model is used when jobs compete for facilities, but it does not allow for splitting job assignments; each job is assigned to one facility.

Question 10

A major objective of loading is to spread the load so that waiting is minimized,flow is smooth and slow,and congestion is avoided.

Accepted Answer

A major objective of loading is to spread the load so that waiting is minimized, flow is smooth and efficient, and congestion is avoided, not to make the flow slow.

Question 11

Sequencing inflexibility occurs when the updating of charts (redrawing them) is supported by software.

Accepted Answer

Sequencing inflexibility refers to the difficulty or inability to change the order of operations or processes, not the updating or redrawing of charts by software.

Question 12

P/OM decisions must often be made with fast data scans,also know as eyeballing,that rely on the assistance of charts such as the Gantt load chart.

Accepted Answer

P/OM decisions often require quick analysis of data, and the Gantt load chart is a helpful tool to visually represent the data for efficient decision-making.

Question 13

The systems approach is called for so that the total number of assignments that are made by the scheduler is minimized.

Accepted Answer

The systems approach is called for to optimize the overall performance and efficiency of the system, not specifically to minimize the total number of assignments made by the scheduler.

Question 14

By using a ratio,the production scheduler who is doing the sequencing gains greater control over the factors.

Accepted Answer

Using a ratio allows the production scheduler to compare different factors and make informed decisions about the sequencing process. This can lead to greater control over production and better optimization of resources.

Question 15

The Gantt layout chart is updated once a week.

Accepted Answer

The frequency of updating a Gantt chart can vary depending on the project's needs, the project manager's preferences, or the organization's practices. It is not fixed to a weekly schedule and can be updated daily, weekly, monthly, or at any other interval as required.

Question 16

If the average completion tim  e is as small as possible,the average customer's order is delayed the minimum necessary time.This can be a primary objective in determining rational loading priorities.

Accepted Answer

The answer of If the average completion tim  e...

Question 17

When determining flow times,beginning at time zero with the first job is the same as saying that release time,called rᵢ,equals zero.This might be the start of a new day,week,etc.

Accepted Answer

When starting at time zero with the first job, it is assumed that the release time of the job is also zero. This release time could be the start of a new day, week, or any other relevant timeframe.

Question 18

The assignment of work and its timing need to be orchestrated.

Accepted Answer

Assigning work and timing it properly is crucial to ensure smooth workflow and effective outcomes.

Question 19

Production scheduling plans are accomplished by the shop loading function and the sequencing function for the job shop.

Accepted Answer

The shop loading function and sequencing function are both important components of production scheduling plans for job shops. The shop loading function involves determining which jobs will be processed and when based on available resources such as equipment and personnel. The sequencing function involves determining the order in which operations will be performed within a job. Both functions are necessary for creating an efficient production schedule in a job shop environment.

Question 20

For each machine,when the SMH index is divided by the actual machine hours available per week,the standard machine hours (SMH) available per week are obtained.

Accepted Answer

Dividing the SMH index by the actual machine hours available per week does not yield the standard machine hours available per week; instead, it typically involves calculating the efficiency or utilization rate of the machines based on their standard and actual operating hours. The standard machine hours available per week are usually predetermined based on the machine's capacity and operational planning.
