Question 1

In the context of operations management,_____ refers to the assignment of start and completion times to particular jobs,people,or equipment.
A) scheduling
B) appointing
C) statistical forecasting
D) demand planning

Accepted Answer

Scheduling is the process of assigning start and completion times to specific jobs, people, or equipment. Appointing refers to choosing individuals to take on specific roles or responsibilities. Statistical forecasting and demand planning involve predicting future demand for products or services. Therefore, scheduling is the best choice for the given context.

Question 2

Two examples of process-focused performance measures for sequencing rules are tardiness and lateness.

Accepted Answer

False

Question 3

The Clarke-Wright Heuristic Method is used to solve the common scheduling problem in logistics that involves determining routes from a central depot or warehouse to many customers.

Accepted Answer

The Clarke-Wright Heuristic Method is commonly used to solve the vehicle routing problem in logistics, where routes are determined from a central depot or warehouse to multiple customers.

Question 4

In the context of sequencing,_____ is the difference between the completion time and the due date of a job.
A) flow time
B) makespan
C) lateness
D) tardiness

Accepted Answer

Lateness is defined as the difference between the completion time and the due date of a job. Flow time is the time it takes for a job to complete from start to finish, regardless of the due date. Makespan is the total time required to complete a set of jobs in a specific order. Tardiness is a specific type of lateness that occurs when a job is completed after its due date. Therefore, the correct answer is C, lateness.

Question 5

In priority dispatching rules,the acronym FNO stands for feasible number of operations remaining.

Accepted Answer

FNO stands for "Fewest Number of Operations remaining," not "Feasible Number of Operations remaining."

Question 6

A requirement of two-resource sequencing rule is that:
A) all jobs must begin at the same time.
B) each job must be processed first on the first resource and then on the second.
C) a maximum of two jobs can be processed at a time on each resource.
D) total processing time must be minimized.

Accepted Answer

Two-resource sequencing rule requires that for each job, it must be processed first on the first resource and then on the second resource. This rule ensures that each job's processing is properly ordered and resources are utilized efficiently. Therefore, option B is the correct choice.

Question 7

Gantt charts are used to:
A) develop a factory layout.
B) track inventory levels over time.
C) monitor planned schedules.
D) forecast personnel requirements.

Accepted Answer

Gantt charts are commonly used in project management to visually represent the planned schedule, tasks, and progress of a project. They are not typically used for developing factory layouts, tracking inventory levels, or forecasting personnel requirements.

Question 8

In the context of sequencing,the earliest due date (EDD)rule:
A) minimizes the maximum jobs past due.
B) maximizes average flow time of jobs past due.
C) maximizes resource utilization of jobs past due.
D) minimizes the average processing time of jobs past due.

Accepted Answer

The EDD rule prioritizes jobs with the earliest due dates, which helps in minimizing the maximum lateness or the number of jobs that are past due.

Question 9

Different industries use different software packages for scheduling because every industry has different problem structures.

Accepted Answer

Different industries have different needs and constraints when it comes to scheduling, and therefore require different types of software packages to address their specific problem structures. A software package that works well for one industry may not be suitable for another.

Question 10

In the context of sequencing,_____ is the time needed to process a given set of jobs.
A) flow time
B) makespan
C) lateness
D) tardiness

Accepted Answer

Makespan refers to the total time required to complete a set of jobs, including processing, setup, and any other necessary tasks. It is a commonly used measure of performance in sequencing problems.

Question 11

In the context of sequencing,the _____ minimizes the average lateness of a set of jobs.
A) shortest processing time rule
B) earliest due date rule
C) first come,first serve rule
D) fewest number of operations remaining rule

Accepted Answer

The shortest processing time rule minimizes the amount of time that each job spends in the system, which ultimately leads to a reduction in the average lateness of the set of jobs. It is one of the most widely used sequencing rules and is effective in reducing the average completion time, regardless of the size or complexity of the job set.

Question 12

In the context of sequencing,the shortest processing time (SPT)rule tends to:
A) maximize the number of jobs in the system.
B) maximize average flow time.
C) minimize resource utilization.
D) minimize work-in-process inventory.

Accepted Answer

The shortest processing time (SPT) rule involves processing the job with the shortest processing time first. By doing so, the SPT rule minimizes the work-in-process inventory, as jobs are completed more quickly and spend less time waiting in the queue. This results in faster throughput and shorter lead times. Therefore, the best choice is D.

Question 13

In the context of sequencing,_____ is the amount of time by which the completion time exceeds the due date of a job.
A) flow time
B) makespan
C) lateness
D) tardiness

Accepted Answer

Tardiness is the amount of time by which the completion time exceeds the due date of a job. Flow time is the total time a job spends in the system, while makespan is the total time needed to complete all jobs. Lateness is the difference between the completion time and the due date, regardless of whether it is positive or negative.

Question 14

In a two-resource sequencing problem,_____.
A) the processing time for each job on each resource is unknown
B) flow time is maximized
C) the goal is to minimize makespan
D) a job can be processed by either of its resources in any sequence

Accepted Answer

In two-resource sequencing problem, the goal is to minimize makespan, which is the time between the start of the first job and the completion of the last job. A and D are incorrect because the processing time for each job on each resource is known, and a job can only be processed by either of its resources in a specific sequence. Option B is also incorrect as flow time is not the objective in this problem.

Question 15

In the context of operations management,triage nurses deciding on the order in which emergency patients are to be treated is an example of _____.
A) appointing
B) sequencing
C) statistical forecasting
D) demand planning

Accepted Answer

Triage nurses deciding on the order in which emergency patients are to be treated is an example of sequencing, which involves determining the order in which tasks or jobs will be performed. The triage nurses take into account the severity of the patient's condition and prioritize them accordingly, making sure that the most critical patients are treated first.

Question 16

Customized scheduling spreadsheets use readily available software such as Microsoft Excel,but may be rather expensive to develop.

Accepted Answer

Customized scheduling spreadsheets can be created using Microsoft Excel, but the development cost may be high due to the need for customization.
