We have a fairly complex object model, but we’re still puzzled – I thought that the definition of “Activation” was that the data matched on all conditions of a rule, and therefore the rule was entered into the agenda (activated).

If that is true, I cannot figure out why we’re experiencing this.

As our number of rules increases, we’re seeing exponential increases in repetitive activation/deactivation pairs, even on rules where we know the data does not match the conditions.

 

Example:

The following rule (abbreviated here) creates an object of type PolicySet if there are none that match the conditions.

I would expect this rule to activate once, then fire, wherein the matching PolicySet is created, and then never activate again since the absence of a matching PolicySet object is never again true.

However, in a rule base of ~4,000 rules, we see this rule activating 975 times and deactivating 975 times. This is just one example – nearly all our rules do this, and it is seriously impacting decisioning performance.

 

Have I misunderstood the meaning of “activation”? Can anyone help me understand this?

 

rule "RS6090.1.12_RF7007_50001012"

        when

                LendingProduct ( $exitStrategyType1 : exitStrategyType )

                Features ( $lienPriority1 : lienPriority )

                DecisionResultsInfo ( $dealRiskCategory1 : dealRiskCategory )

                TransactionDetail ( $parentTransactionDetail1Id : myId )

                not

                (

                        PolicySet ( $parentPolicySet_1_Id : myId, parentId == $parentTransactionDetail1Id )

                        and

                        PolicySetIdentifier ( parentId == $parentPolicySet_1_Id

,  lienPriority == $lienPriority1

                                , exitStrategyType == $exitStrategyType1

, dealRiskCategory == $dealRiskCategory1)

                )

        then

                // Content removed… rule creates the policy set and the policy set identifier, and initializes all appropriate elements

                // After doing so, why does it activate/deactivate 1800+ times in a rule base of 4000 rules?

                System.out.println("6090 fired.");

End

 

Thanks.
