Consider the following batch flow process consisting of three process steps performed by three machines.

	Step 1	Step 2	Step 3
Processing time	2 mins/unit	3 mins/unit	1.5 mins/unit
Setup Time	20 mins	No setup	No setup

1. Assume that the batch size is 10 parts. What is the capacity of the process?
2. For a batch size of 50 parts, which step is the bottleneck for the process?
3. What is the ideal batch size (i.e. one that minimizes inventory without affecting process capacity)?
