A stamping operation is considering two options for processing its parts. Option 1 produces in a large process batch (pcs per lot, Ns) of 3600 pcs. And has an existing setup time (ts) of 2400 seconds with a coefficient of variation for the setups of 0.25. Option 2 would have reduced the process batch by 50% and process 1800 pcs in a given batch. The coefficient of variation for the setup would remain at 0.25, but would have reduced setup time by 50%. In both case the average processing time is 10 sec/pc with a coefficient of variation of 0.25. Which option is preferable?
