the shift definition of the different processors

My quetion is：

the processor 1 need run 3 shitfs by day 3*8=24
and the processor 2 need run 2 shifts by day 2*8
the last processor 3 jusn only have one shift 8 hours/day

how can setup for these processer, thank you very much

may be you use timetables
