Q2. Three-step process
Consider the following batch flow process consisting of three process steps performed by three machines:
Step 1 Step 2 Step 3
| Processing time: 2 minute/part
No Setup |
| Processing time: 1.5 minute/part
No Setup
|
| Processing time: 1 minute/part
Setup time: 20 minutes |
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.
Find the best batch size that achieves a flow rate of 24 parts per hour.
