Problem: Consider a single machine that has access to unlimited supply of raw material. The machine works continuously to process raw material one unit at a time at a rate of 30 units per hour. Does the processing time distribution affect any of your answers to the above questions? Explain why. (c) Assume from here on that the processing time at this machine (let's call it machine 1) has the exponential distribution. Machine 1 feeds into a single machine (machine 2) where the material gets processed further. What is the arrival rate to this machine (assuming there is ample waiting room at machine 2)?
