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. Assume Step 1 is done first, then Step 2, and Step 3 is last; there is unlimited buffer storage space between process steps; and demand is high.

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?
