Consider the following batch flow process consisting of three process steps performed by three machines:
Step 1 Step 2 Step 3
Processing Time: 1 min/part 2 min/part 1.5 min/part
Setup Time: 20 mins No Setup No Setup
Work is processed in batch 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. There are no inventory buffers between steps.
