Hi all, I have changed the Vehicle Routing example to suit my domain model. My domain is: - Consultant (the person that will drive to a DeliveryPlace and spent some time there, each Consultant has a max total time available, implements Appearance) - DeliveryPlace (the place where a Consultant will drive to and spent some time making a delivery, implements Appearance) - Location (a Consultant has a home and a DeliveryPlace has a location) I need the soft constraints to take into account returning from last DeliveryPlace to the home location of the Consultant. But how do I know if a DeliveryPlace is the last one so I can add that to the rule ? Right now I have a rule that just takes each DeliveryPlace and calculates minutes to previousAppearance: rule "minutesToPreviousAppearance" when $deliveryPlace : DeliveryPlace(previousAppearance != null, $minutesToPreviousAppearance : minutesToPreviousAppearance) then insertLogical(new IntConstraintOccurrence("minutesToPreviousAppearance", ConstraintType.NEGATIVE_SOFT, $minutesToPreviousAppearance, $deliveryPlace)); end -- View this message in context: http://drools.46999.n3.nabble.com/Planner-Vehicle-Routing-but-with-return...
