There are 9 (3 shifts for 3 hospitals) - Planning variable: ShiftAssignment.get/setDoctor() - Planning values for that variable: 10 doctors So Planner will put a doctor in each of those 9 ShiftAssignments and 1 doctor won't be assigned to any shift. Actually, Planner might assign the same 2 doctor to 2 different ShiftAssignments if none of the constraints are broken (such as "no 2 ShiftAssignements at the same time for the same doctor"). See nurse rostering example. Play around with it. Take a look at this video about contentious planning with nurse rostering: http://blog.athico.com/2012/08/continuous-planning-video.html Mentally replace "nurse" with "doctor" and "department" with "hospital".
