Line balancing is a major factor in the design and scheduling of low volume systems because of batch processing.
|
False

|
|
Scheduling in intermediate-volume systems has three basic issues: run size, timing, and sequence.
|
True

|
The output of the system cannot exceed the output of the bottleneck operation(s).
|
True
|
|
|
Sequencing is concerned with the order in which jobs are done, while loading is concerned with assigning assigning jobs to work centers or workstations.
|
True
|
|
|
Priority rules generally assume that job setup cost is independent of processing sequence of jobs.
|
True

In the decision-making hierarchy, scheduling decisions are the final step in the transformation process before actual output occurs.
|
False
|
|
|
Makespan is the total time needed to complete a group of jobs.
|
True
|
|
|
