The following information relates to Ramesy Manufacturing:
To produce a unit of product:
Cutting department 5 minutes per unit
Welding department 8 minutes per unit
Polishing department 3 minutes per unit
Finishing department 4 minutes per unit
There is a wait time of 5 minutes before the cutting department begins a batch, 15 minutes between the
cutting and welding departments, a move and pre-wait between welding and polishing of 12 minutes,
and a move and pre-wait between the polishing and finishing departments of 8 minutes.

23. Refer to Figure 15-2. If Ramesy produces in batches of 10 units, how much time would have elapsed
by the time the 10th unit is produced under a manufacturing cell environment (assuming the cell is
processing continuously)?
a. 65 minutes
b. 60 minutes
c. 150 minutes
d. some other amount
ANS: A
Assuming the cell is processing continuously, one unit requires 20 minutes of processing time, and
each unit starts 5 minutes after the prior unit (the time it takes each unit to complete cutting process).
Time elapsed
First unit 20 minutes
Second unit 25 minutes
Third unit 30 minutes
