Question 6 (Setup Everywhere) Consider the following batch-flow process consisting of three process steps performed by three machines. Process Step Step 1 Step 2 Step 3 Processing Time 0.25min./unit Setup time 30 min 0.20 min./unit 20 min 0.15 min./unit 45 min 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 1 if the batch size is 35 parts? b. For what batch sizes is step 1 (2, 3) the bottleneck?
