An order for 100 of a product is processed on operation X and operation Y. The setup time on X is 50 minutes, and the run time per piece is 9 minutes. The setup time on Y is 30 minutes, and the run time is 6 minutes per piece. It takes 20 minutes to move a lot between X and Y. Since this is a rush order, it is given top priority (president's edict) and is run as soon as it arrives at either work center. It is decided to overlap the two operations and to split the lot of 100 into two lots of 60 and 40. When the first lot is finished on operation X, it is moved to operation Y where it is set up and run. Meanwhile, operation X completes the balance of the 100 units (40) and sends the units over to operation Y. These 40 units should arrive as operation Y is completing the first batch of 60; thus, operation Y can continue without interruption until all 100 are completed. How much time is saved in manufacturing lead time (MLT) with overlapping? O 200 minutes O 150 minutes O 360 minutes O 450 minutes 300 minutes +

Transcribed Image Text:An order for 100 of a product is processed on operation X and operation Y.
The setup time on X is 50 minutes, and the run time per piece is 9
minutes. The setup time on Y is 30 minutes, and the run time is 6 minutes
per piece. It takes 20 minutes to move a lot between X and Y. Since this is
a rush order, it is given top priority (president's edict) and is run as soon as
it arrives at either work center. It is decided to overlap the two operations
and to split the lot of 100 into two lots of 60 and 40. When the first lot is
finished on operation X, it is moved to operation Y where it is set up and
run. Meanwhile, operation X completes the balance of the 100 units (40)
and sends the units over to operation Y. These 40 units should arrive as
operation Y is completing the first batch of 60; thus, operation Y can
continue without interruption until all 100 are completed. How much time
is saved in manufacturing lead time (MLT) with overlapping?
O 200 minutes
O 150 minutes
O 360 minutes
O 450 minutes
O 300 minutes
