I'm new Drools Planner user, so sorry if my question proved to be trivial. Simplified problem definition: Facts: Workorder Technician Planning entity: WorkorderAssignement { private List<Technician> technicianList; private Workorder workorder; } Workorder depends of his definiiton maybe assigned to variable number of technicians. So, some of them require only ONE technician, but other requires TWO technicians. Is there possible build optimized technician list in this case? -- View this message in context: http://drools.46999.n3.nabble.com/Drools-Planner-planning-variable-as-lis...
