[rules-users] Rules for Hierarchical Type Calculation Formulas

[Don Cameron]

We have been using a custom rules engine successfully for our 1000+

rules for our student loans application, but these rules are decision

based types rules (if then else).

 

For assessing loan amounts for our student loan application, we have

over 400+ calculation formulas plus decision logic.  These formulas are

mostly simple:

 

TotalEligilbleLoanAmount = Min(TotalNeed - TotalResource,

MaxAllowedAmount)

      TotalNeed = Tuition + LivingAllowance + ChildCareExpenses

            ChildCareExpenses = NumberOfChildren * PerChildAmount

      TotalResource = EmploymentEarnings + Scholarships + Assets

 

(however there are 400+ formulas and the hierarchy gets up to 20 deep)

 

Is it possible to implement something like this in Drools? Will it be

maintainable and performant?

 

Thanks

Don
