Can you do this question without excel? 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 ce $^2$of $0.25.$Machine B has a mean effective process time of $0.85$hour and an SCV of four. a $.$For an arrival rate of $0.92$job per hour with ca $^2=1,$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 hour with ca $^2=1.$Recompute the average time spent at the stations for both machine A and machine B $.$Compare with a and explain the difference in results. 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 represent?
