1. What is Takt time?
Junior
A.available production time divided by customer demand, the pace at which one unit must leave the line
B.sum of task times divided by the number of stations times the cycle time, with balance delay as its complement
C.actual time a workstation takes to complete one unit, which must be at or below the takt time for the line to keep up
D.computing dependent-demand component needs by exploding the BOM against the master schedule, netting inventory and offsetting by lead time
A.Cycle time — availability × performance × quality of a machine, with 85% regarded as world class
B.Cycle time — computing dependent-demand component needs by exploding the BOM against the master schedule, netting inventory and offsetting by lead time
C.Cycle time — actual time a workstation takes to complete one unit, which must be at or below the takt time for the line to keep up
D.Cycle time — breakdowns, setup and adjustment, minor stops, reduced speed, start-up rejects and production rejects, the categories that pull OEE down
11. Which term means: "computing dependent-demand component needs by exploding the BOM against the master schedule, netting inventory and offsetting by lead time"?
A.Material requirements planning — actual time a workstation takes to complete one unit, which must be at or below the takt time for the line to keep up
B.Material requirements planning — computing dependent-demand component needs by exploding the BOM against the master schedule, netting inventory and offsetting by lead time
C.Material requirements planning — availability × performance × quality of a machine, with 85% regarded as world class
D.Material requirements planning — elapsed time from order release to completion, made up of queue, setup, run and move time with queue usually the largest
17. Which term means: "breakdowns, setup and adjustment, minor stops, reduced speed, start-up rejects and production rejects, the categories that pull OEE down"?
A.Six big losses — elapsed time from order release to completion, made up of queue, setup, run and move time with queue usually the largest
B.Six big losses — sum of task times divided by the number of stations times the cycle time, with balance delay as its complement
C.Six big losses — actual time a workstation takes to complete one unit, which must be at or below the takt time for the line to keep up
D.Six big losses — breakdowns, setup and adjustment, minor stops, reduced speed, start-up rejects and production rejects, the categories that pull OEE down
A.Line balance efficiency — sum of task times divided by the number of stations times the cycle time, with balance delay as its complement
B.Line balance efficiency — elapsed time from order release to completion, made up of queue, setup, run and move time with queue usually the largest
C.Line balance efficiency — theory-of-constraints scheduling where the constraint sets the pace, a time buffer protects it and material release is tied to its consumption
D.Line balance efficiency — available production time divided by customer demand, the pace at which one unit must leave the line
A.Bottleneck — availability × performance × quality of a machine, with 85% regarded as world class
B.Bottleneck — available production time divided by customer demand, the pace at which one unit must leave the line
C.Bottleneck — resource whose capacity is below the demand placed on it, so an hour lost there is an hour lost for the whole plant
D.Bottleneck — breakdowns, setup and adjustment, minor stops, reduced speed, start-up rejects and production rejects, the categories that pull OEE down
26. Which term means: "theory-of-constraints scheduling where the constraint sets the pace, a time buffer protects it and material release is tied to its consumption"?
A.Drum-buffer-rope — resource whose capacity is below the demand placed on it, so an hour lost there is an hour lost for the whole plant
B.Drum-buffer-rope — breakdowns, setup and adjustment, minor stops, reduced speed, start-up rejects and production rejects, the categories that pull OEE down
C.Drum-buffer-rope — theory-of-constraints scheduling where the constraint sets the pace, a time buffer protects it and material release is tied to its consumption
D.Drum-buffer-rope — availability × performance × quality of a machine, with 85% regarded as world class
