I've answered this to the user mailing list, please post any follow ups there http://www.jboss.org/drools/lists.html schumacv schreef: Do you mean work orders for machine queues as in "work queue planning"? One way that works well on vehicle routing and work queue planning is to make smarter moves. Take a look at the Move implementation in the smart version of the TravelingTournament example. Basically, the idea is to make a non-caching SqueezeWorkOrderBetweenTwoOtherWorkOrdersMoveFactory that creates SqueezeWorkOrderBetweenTwoOtherWorkOrdersMove. Where the work order is taken away, the following work orders are pulled forward, where the work order is added, the following work orders are pushed into the future. With kind regards, Geoffrey De Smet
