A capacity constrained industrial process consists of 2
sequential steps. Step 2 has a total setup time of 40 minutes per
batch while step 1 has no setup time. The activity time for step 1
is 2 minutes per part, for step 2 is 1 minute per part? An entire
batch must be processed at each step before the next step can begin
to work on parts from that same batch.
a) Assuming a batch size of 20, what is the capacity (flow rate) of
the entire process and what is the bottleneck?
b) What batch size will yield the optimal output rate for this
process?
