Drools裁定Optaplanner出错-重新分配相同的资源

如何解决Drools裁定Optaplanner出错-重新分配相同的资源

我正在尝试为到达泊位的船只制定规则。到达泊位的船只需要分配一组“ k”资源，其中“ k”取决于船只的长度。整个船只停留时间分为“ n”个时隙，目标是在所有“ n”个时隙中拥有相同的“ k”资源。 “ k”资源是有序且连续的值，并在船只到达时隙中分配，我希望其余时隙也具有与“ k”资源相同的顺序。我为此编写了以下规则，但由于我希望它起作用而无法正常工作。有人可以帮我解决为什么发生这种情况吗？

    when
        ResourceAssignment($vessel: myVessel,$resource: myResource,$resource != null,$timeSlot: myWindow,$timeSlot == myVessel.getVesselArrivalTimeSlot(),$id: id,$resourcesrequired: myVessel.getResourcesrequired())
        ResourceAssignment(myVessel == $vessel,id > $id,eval(((id-$id) % $resourcesrequired) == 0),myWindow.getTimeSlotId() > $timeSlot.getTimeSlotId(),myResource != $resource,$nextTimeSlot: myWindow.getTimeSlotId(),$nextId: id,$nextResource: myresource)
    then
        int resourceDiffPenalty =  Math.abs($nextResource.getResourceStart()-$resource.getResourceStart())*100;
        scoreHolder.addHardConstraintMatch(kcontext,-resourceDiffPenalty);
end

ResourceAssignment是我的实体类，并具有以下定义：

public class ResourceAssignment {
    private Long id;
    private Vessel myVessel;
    private TimeSlot myWindow;
    private Resource myResource; // planning variable 1
    private QC myCrane; // planning variable 2
}
