Time left 1:15:26 2 Queues and Space Allocation This is very similar to the first exam (with the key difference coming in questions 21 and 22). An auto parts company is in the construction phase of a new plant in Lake Charles, LA. The center- piece of the operation is a stamping machine that in its basic configuration) can process p = 40 parts per hour (on average). Parts arrive at an average rate of 1 = 36 units per hour. Assume all processing (service) times and interarrival times are exponentially distributed. How busy is the machine, on average, p? a 0.5 b. 0.9 C. 0.8 d. 0.4 What is the probability distribution of L (the number of parts in the system)? 3. Geometric(02) 6. Geometric(0.1) c. Geometric (0.4) d. Geometric (0.5) 14 What is the mean number of parts in the system, E [L]? 11 LA
