1. OPERATIONS MANAGEMENTChapter 15 – Short-Term Scheduling Classroom discussion questions to accompany Heizer/Render Principles of Operations Management, 6e and Operations Management, 8e (to be used in conjunction with wireless polling devices or other classroom interaction activities) Jay Heizer Barry Render Chapter 15

2. Scheduling is concerned with determining the quantity and timing of production for: • 0-2 months ahead. • 3-18 months ahead. • 18-24 months ahead. • 24-48 months ahead. Chapter 15

3. Which is not a direct benefit of effective scheduling? • Lower costs. • Faster delivery. • Improved quality. • Dependable delivery. Chapter 15

4. Scheduling decisions begin with: • Capacity planning. • Aggregate planning. • Master scheduling. • Job sequencing. Chapter 15

5. Which of the following is true regarding forward scheduling? Forward scheduling is the scheduling of: • The end items or finished products. • Jobs as soon as the requirements are known. • The start items or component parts. • The final operation first beginning with the due date. • Jobs according to their profit contributions. Chapter 15

6. The scheduling criterion “minimize WIP” is evaluated by: • Average completion time per job. • Percent of time facility is utilized. • Average number of jobs in the system. • Average number of late days. Chapter 15

7. The scheduling criterion “minimize customer waiting time” is evaluated by: • Average completion time per job. • Percent of time facility is utilized. • Average number of jobs in the system. • Average number of late days. Chapter 15

8. Assigning jobs to work centers is referred to as: • Loading. • Sequencing. • Dispatching. • Scheduling. Chapter 15

9. Determining the order in which jobs should be done at each work center is referred to as: • Loading. • Sequencing. • Dispatching. • Scheduling. Chapter 15

10. Which item contains important information for an item’s flow through the shop? • Item master file. • Work center master file. • Control file. • Routing file. Chapter 15

11. Gantt charts are useful for: • Loading and sequencing. • Sequencing and dispatching. • Dispatching and loading. • Scheduling and loading. Chapter 15

12. A popular use of linear programming in scheduling is for: • Loading. • Sequencing. • Dispatching. Chapter 15

13. Which sequencing rule is generally the best for minimizing job flow? • Shortest processing time. • First come, first served. • Earliest due date. • Longest processing time. Chapter 15

14. Which sequencing rule is generally the best for minimizing tardiness? • Shortest processing time. • First come, first served. • Earliest due date. • Longest processing time. Chapter 15

15. Which sequencing rule is more important in the service than the manufacturing sector? • Shortest processing time. • First come, first served. • Earliest due date. • Longest processing time. Chapter 15

16. Which sequencing rule minimizes the processing time for sequencing a group of jobs through two work centers? • Shortest processing time. • First come, first served. • Earliest due date. • Johnson’s rule. • Longest processing time. Chapter 15

17. Which technique does not help to alleviate a bottleneck? • Increasing capacity of the constraint. • Developing alternative routing, processing procedures, or subcontractors. • Moving inspections and tests to a position just after the bottleneck. • Scheduling throughput to match the capacity of the bottleneck. Chapter 15

18. A recent advance in short term scheduling that makes use of expert systems and simulation in solving dynamic scheduling problems is: • Forward scheduling. • Backward scheduling. • Infinite scheduling. • Finite scheduling. • Progressive scheduling. Chapter 15
