File: ch17, Chapter 17: Scheduling True/False 1. Scheduling specifies when labor, equipment and facilities are needed to produce a product. Ans: True Difficulty: Easy Feedback: Objectives in Scheduling 2. Scheduling is considered the last stage of the planning process. Ans: True Difficulty: Easy Feedback: Objectives in Scheduling 3. The wide variety of jobs in a job shop makes scheduling difficult. Ans: True Difficulty: Easy Feedback: Objectives in Scheduling 4. Managers typically use multiple objective when constructing a schedule. Ans: True Difficulty: Easy Feedback: Objectives in Scheduling 5. Minimizing overtime is one of several objectives that could be considered when constructing a schedule. Ans: True Difficulty: Easy

Feedback: Objectives in Scheduling 6. Job shop scheduling is usually performed by skilled machine operators. Ans: False Difficulty: Easy Feedback: Objectives in Scheduling 7. The process of assigning work to limited resources is known as scheduling. Ans: False Difficulty: Moderate Feedback: Loading 8. Sequencing involves determining the order in which jobs are released to the shop floor. Ans: False Difficulty: Hard Feedback: Sequencing 9. The sequence in which jobs should be processed is determined using linear programming. Ans: False Difficulty: Moderate Feedback: Sequencing 10. Determining the optimal allocation of jobs to machines or workers can be solved using the assignment method of linear programming. Ans: True Difficulty: Moderate Feedback: Sequencing

11. The process of prioritizing jobs that have been assigned to a resource is called sequencing. Ans: True Difficulty: Easy Feedback: Sequencing 12. The time required for a job to move through the system is referred to as flow time. Ans: True Difficulty: Moderate Feedback: Sequencing 13. All sequencing rules strive to optimize both processing efficiency and due date performance. Ans: False Difficulty: Moderate Feedback: Sequencing 14. Johnson’s rule gives an optimal sequence for jobs processed serially through a two step system. Ans: True Difficulty: Moderate Feedback: Sequencing 15. The shortest processing time (SPT) rule is most useful when the job shop is not congested. Ans: False Difficulty: Moderate Feedback: Sequencing

16. The longest processing time (LPT) rule tends to complete larger jobs in-house when subcontracting is anticipated. Ans: True Difficulty: Moderate Feedback: Sequencing 17. The first-come, first-served (FCFS) sequencing rule should be only used when operating at high levels of capacity. Ans: False Difficulty: Moderate Feedback: Sequencing 18. Gantt charts show the planned and yet to be completed activities against total activities. Ans: False Difficulty: Moderate Feedback: Objectives in Scheduling 19. Increasing the capacity of a work center that is a bottleneck increases output. Ans: True
