(Setup Everywhere) Consider the following batch-flow process consisting of three process steps performed by three machines:

Work is processed in batches at each step. Before a batch is processed at a step, the machine at that step must be set up. ( During a setup, the machine is unable to process any product.) Assume that there is a dedicated setup operator for each machine (i.e., there is always someone available to perform a setup at each machine.)

a. What is the capacity of step I if the batch size is 35 parts?

b. For what batch sizes is step I (2, 3) the bottleneck?

Step 1 Activity Time: A 0.25 Minute/Part Setup Time: 30 Minutes Step 2 Activity Time: 0.20 Minute/Part Setup Time: 20 Minutes Step 3 Activity Time: 0.15 Minute/Part Setup Time: 45 Minutes
