java - Optaplanner 不使用其他 BinAvailabilty 来获取分配给事件

Question

        @PlanningEntity
        public class BinAvailablity {
            private int id;
            private Interval interval;
            private Bin bin;
            private int roomMax;
            @InverseRelationShadowVariable(sourceVariableName = "binAvailablity")
            private List<Event> events = new ArrayList<>();
            private List<Interval> nonAvailablity;
        }


    public class Event {

        private int id;
        @CustomShadowVariable(variableListenerClass = IntervalAssigningListener.class,
                sources = {@PlanningVariableReference(variableName = "binAvailablity")})
        private Interval interval;//assignning listener variable
        private boolean isPinned;
        private TotalTime totalTime;
        @PlanningVariable(valueRangeProviderRefs = "binAvailablities")
        private BinAvailablity binAvailablity;//plannig variable
        private List<Staff> staffList;
        private List<Equipment> equipmentList;
        private List<Interval> nonAvailability;}

我的配置是:-

@PlanningSolution 公共(public)类 EventBinAssignation {

private String id;

@PlanningScore
private HardSoftScore score;

@ProblemFactCollectionProperty
@ValueRangeProvider(id = "binAvailablities")
List<BinAvailablity> binAvailablities;

@PlanningEntityCollectionProperty
List<Event> events;

}

我已经使用 Event 和 BinAvailability 创建了两个实体。我需要将事件分配给 binAvailability。但 Optaplanner 仅将事件分配给第一个 binAvailability。 Optaplanner 没有使用任何其他 binAvailability 来分配分数卡住的事件，但它不使用任何其他 binAvaillbity 来分配具有某些特定条件的事件。所以请帮忙。

Answer 1

如果 OptaPlanner 仅将事件分配给第一个 binAvailability，则可能是因为您的硬约束不匹配(在您的 ScoreDrl 中)。打开 TRACE 日志记录并查找每个 CH 移动期间的分数 数字。

或者将 System.out.println 放入 DRL 中该约束的 then 中。 或者迁移到 ConstraintStreams 并在 penalize() matchWeighter lamdba 中放置一个调试器断点。
