Consider two different machines A and B that could be used at a station. Machine A has a mean effective process time te of 1.0 hours and an SCV C2 = 0.25. Machine B has a mean effective process time of 0.85 hour and an SCV of 4. (a) For an arrival rate of 0.92 job per hour with c = 1, which machine will have a shorter average cycle time? (b) Now put two identical machines of type A (in parallel) at the station and double the arrival rate. What happens to cycle time? Do the same for machine B. Which type of machine produces shorter average cycle time? (c) With only one machine at a station, let the arrival rate be 0.95 job per hour with c = 1. Recompute the average time spent at the stations for both machine A and machine B
