Consider this batch flow process consisting of process steps performed by three machines: Step 1 Step 2 Step 3 Activity time 0.25 minute/part Activity time: 0.20 minute/part Activity time 0.15 minute/part Setup time 30 minutes Setup time: 20 minutes Setup time: 45 minutes Work is processed in batches at each step. The machine must be set up before a batch may be processed at a step. 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.) 50. So Consider the styrement: "Step 1 is the bottleneck for any batch size larger than X." 4. What X makes this statement correct? (parts/batch) (B) (A) '/ 125 (C) 175 (D) 150 No X makes this statement true
