Deck 15: Operations Scheduling and Sequencing

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

Answer 1

scheduling

Question 2

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

Answer 2

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.

Answer 3

True

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

Question 5

In priority dispatching rules,the acronym FNO stands for 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.

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.

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.

Question 9

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

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

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

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.

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

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

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

Question 16

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