Consider two machines in series as would be the case on a manufacturing line where a part has an operation performed at one machine and then moves to the next one. Both machine haves an effective processing time of 1.4 hours per job and an effective SCV of 10. Jobs arrive in a steady stream at a rate of 0.65 jobs per hour, and they come from all over the plant so the SCV of arrivals is estimated to be 1.

So now our boss is interested in purchasing a new machine with the same capacity but less effective variability (still time of 1.4 hours but with an associated SCV of 0.5) that can be used at either station. If we place the machine at the FIRST station what would be the cycle time through the system. Show all work this is a longish problem so allow time.
