sqa 5. Consider two different machines A and B that could be used al CHR a mean effective process time t, of 1.0 hours and an SCV c2 of 0.25. Machine B has a mean effective process time of 0.85 hour and an SCV of four. (Hint: You may find a simple spreadsheet helpful in making the calculations required to answer the following questions.) 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 machines of type A at the station and double the arrival rate (i.e., double the capacity and the throughput). 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 each station, let the arrival rate be 0.95 job per a hour with c2= 1. Recompute the average time spent at the stations using both machines A and B. Compare with a. d. Consider the station with one machine of type A. i. Let the arrival rate be one-half. What is the average time spent at the station? What happens to the average time spent at the station if the arrival rate is increased by one percent (i.e., to 0.505)? What percentage increase in wait time does this represent? ii. Let the arrival rate be 0.95. What is the average time spent at the station? What happens to the average time spent at the station if the arrival rate is increased by one percent (i.e., to 0.9595)? What percentage increase in wait time does this Ve represent?
