ch16 Student: ___________________________________________________________________________ 1. "Flow-shop scheduling" is used in high volume systems. True False 2. Line balancing is a major factor in the design and scheduling of low volume systems because of batch processing. True False 3. Scheduling in intermediate-volume systems has three basic issues: run size, timing, and sequence. True False 4. When operations are often bottlenecked, additional planned idle time will improve the throughput in those areas. True False 5. When orders exceed our capacity, priority rules are used to select which orders will be accepted. True False 6. The term loading, as used in scheduling, refers to choosing the order in which jobs will be processed in low-volume systems. True False 7. Loading is the determination of which work centers should perform which jobs. True False 8. A Gantt chart is a basic scheduling tool but works best for high-volume systems. True False 9. A Gantt chart is a basic scheduling tool that is most useful in low-volume systems. True False 10. A schedule chart depicts the loading and idle times for a group of machines or departments. True False 11. The output of the system cannot exceed the output of the bottleneck operation(s). True False 12. The elimination of idle time on both bottleneck and non-bottleneck operations must be accomplished to optimize output. True False 13. As long as the bottleneck operations are used effectively idle time in non-bottleneck operations will not affect the overall productivity of the system. True False 14. The quantity sent to a bottleneck operation could be split into two or more process batches to better utilize a bottleneck resource rather than process the entire batch. True False 15. Splitting a large lot after one operation beyond a bottleneck operation would reduce the overall waiting time of the bottleneck operation. True False

16. Input/output (I/O) control refers to monitoring the productivity changes since productivity is determined by the ratio of Output to Input. True False 17. Infinite loading and finite loading are two major approaches used to load work centers. True False 18. A schedule chart can be used to monitor job progress. True False 19. The assignment model seeks an optimum matching of tasks and resources. True False 20. Sequencing is concerned with the order in which jobs are done, while loading is concerned with assigning jobs to work centers or workstations. True False 21. Priority rules are widely used to sequence jobs in high-volume systems. True False 22. The assignment method is limited to a maximum of two jobs per resource. True False 23. Priority rules generally assume that job setup cost is independent of processing sequence of jobs. True False 24. In a single work center, makespan improvement can be accomplished by selecting the optimal sequencing rule.
