Consider two machines, Machine A is a flexible machine, with no setups, but has somewhat variable process times. Natural process time of Machine A is to = 1.3 hours and CV of co = 0.4. Machine B performs an average of Ns = 5 parts between setups and has natural process times with mean of to = 1.1 hours and a CV of co = 0.25. The average setup time is ts = 1 hours with a CV of cs = 0.25. Which machine is better? Calculate their effective capacity first and compare them and then compute ( ce²) values for both machine A and B and compare the effective variably for both machines in this case? Which machine has less variability?
