When a workstation switches to processing a unit with a different color, the workstation incurs a setup.$$So the process batch size$$ here is $4$ units.$$

Each workstation above begins processing the units currently at their workstation at time zero and passes units to the next workstation when it completes processing $4$ units of the same color.

$3.$ With process batch sizes $=4$ and transfer batch sizes $=1,$ what is the manufacturing lead time of unit $1$ in the black batch?$$Answer $3$ Question $15$

$4.$ What is the makespan of the black batch?$$Answer $4$ Question $15$

$5.$ Cutting transfer batch sizes will result in Answer $5$ Question $15$no changea decreasean increase in work$-$in$-$process inventory and Answer $6$ Question $15$an increaseno changea decrease in manufacturing lead times.

$6.$ Cutting transfer batch sizes will result$$ in Answer $7$ Question $15$an increasea decreaseno change in the makespan of the next process batch which enters the system.
