Currently set-up time for a work center schedules at anytime during each selected shift. A lights out operation is functional, however a lights out operation is not manned and an operator cannot do the next set-up. This is capacity that is not utilized and cannot be utilized until the next staffed shift comes on.
If each shift selected within the work center was selectable to be manned or unmanned, then JB scheduling could allow/not allow the next set-up to be completed during that shift. If not allowed, the next set-up would continue at the start of the next manned shift.
