Three-step Process with Setup Time: Consider the following batch flow process consisting of three process steps performed by three machines, one at each step (as shown in the attached pdf figure with data also provided in the table below). Step # Step 1 Step 2 Step 3 Processing Time 1 Minute/Part 2 Minutes/Part 1.5 Minutes/Part Setup Time 20 minutes No Setup No Setup 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. What batch size would you choose assuming that all units of a batch stay together for the entire process? Notes: This question is similar to the Cutting, Section 1, Section2, Finishing example in the Process Interruptions & Batching notes and examples in the practice problems. If you have understood those examples, you should be able to answer this question.
