Consider a line consisting of two machines in series. The first machine on average, te(1) = 8 minutes to complete a job. The second machine takes te(2) = 5 minutes. Both machines have exponential process times. (ce(1) = ce(2) = 1). Between the two machines there is enough room for four jobs. Using this information .

a) First consider what would happen if there were an infinite buffer. What is the arrival rate and utilization of the second machine? Use the M/M/1 formulas to compute the other performance measures for the second machine (WIP, TH and CT)

b) Consider the finite buffer case. First compute throughout for the finite buffer. Partial WIP (WIPP), CT and WIP
