(A) The feeder-selector device at one of the workstations of anassembly machine has a
feed rate of 45 components/min and provides a throughput of onepart in five. The ideal
cycle time of the assembly machine is 6 sec. The low-level sensoron the feed track is set at
10 components, and the high-level sensor is set at 25components.
(a) How long will it take
for the supply of components to be depleted from the high-levelsensor to the low-level
sensor once the feeder-selector device is turned off?
(b) How long will it take for the components
to be resupplied from the low-level sensor to the high-levelsensor, on average,
after the feeder-selector device is turned on?
(c) What are the time proportions that the
feeder-selector device is turned on and turned off?
