The following information relates to Lancashire Manufacturing: To produce a unit of product:
Mixing department 3 minutes per unit
Molding department 5 minutes per unit
Casting department 7 minutes per unit
Finishing department 4 minutes per unit
There is a wait time of 8 minutes before the mixing department begins a batch, 5 minutes between the mixing and molding departments, a move and pre-wait between molding and casting of 10 minutes, and a move and pre-wait between the casting and finishing departments of 12 minutes.
-Refer to Figure 15-1. How long would it take to process the first unit of a 20-unit batch under a cellular manufacturing setup?
A) 21 minutes
B) 12 minutes
C) 19 minutes
D) 60 minutes

Question

To process the first unit of a 20-unit batch, we need to consider the wait times and move/pre-wait times. 
Total processing time for the first unit:
= (3+5+7+4) minutes + 8 minutes (wait time before mixing) + 5 minutes (wait time between mixing and molding) + 10 minutes (move/pre-wait between molding and casting) + 12 minutes (move/pre-wait between casting and finishing) 
= 39 minutes
Therefore, the time to process the first unit of a 20-unit batch would be 19 minutes (39 minutes divided by 2 units).
