Consider the following process consisting of three process steps performed by three
resources:
Step 1
Step 2
Step 3
Step 1
Step 2
Step 3
Setup Time(min)
30
|No Setup No Setup
Processing Time(min) 1min/part 2min/part 1.5min/part
Work is processed in batches at each step. Before a batch is processed at step 1, the
machine has to be set up.
During a setup, the machine is unable to process any product.
For a batch size of 40 parts, what is the capacity of stage 1 in (parts per minute)?
0.57
For a batch size of 40 parts, what is the capacity of the process in (parts per minute)?
0.5
For a batch size of 12 parts, what is the capacity of the process in (parts per minute)?
0.28
What is the optimal batch size for the process if demand is 0.2 parts/min? 12
When we remove inventory buffers from the process and choose the batch size to
be 12, what is the process capacity (in parts per minute)? 0.6
