Question: Consider a single - machine workstation. Parts arrival at a rate of 1 5 parts / hr . Arrival CV is 0 . 5 .

Consider a single-machine workstation. Parts arrival at a rate of 15 parts/hr. Arrival CV is 0.5. The station has a mean effective process time 3 mins and the standard deviation is also 3 mins. Assume an M/M/1 queue, compute , CT and WIP. How would these numbers change if we added an identical machine into the workstation.
