Why not use a Fact that contains your result? In DRL terms it'd look like this:-
rule "one" when $r : Result( $score : score ) Applicant( numberOfLoans > 1 ) then $r.setScore( $score + 5 ); update( $r ); end rule "two" when $r : Result( $score : score ) Applicant( disposableIncome < 20000 ) then $r.setScore( $score + 10 ); update( $r ); end The result could equally just contain the factors influencing the score with a low salience rule then calculating the final score:- rule "one" salience 100 when $r : Result() Applicant( $nl : numberOfLoans ) then $r.setNumberOfLoans( $nl ); update( $r ); end rule "two" salience 100 when $r : Result() Applicant( $di : disposableIncome ) then $r.setDisposableIncome( $di ); update( $r ); end rule "calculate score" salience 200 when $r : Result( $nl : numberOfLoans > 1, $di : disposableIncome < 20000 ) then $r.setScore( 20 ); update( $r ); end On 23 November 2011 09:44, lansyj <lans...@gmail.com> wrote: > hi folks > > We are working on a requirement that requires us to have multiple rules > that > could fire for a given input and for all the rules that fire, we would want > to cumulate the consequence to reach the final consequence. > > As an example, if we want to identify the credit score for a person, based > on his gender you might want to assign/increment/decrement the score, then > based on nationality, and so on. > > So, considering the long list of such criteria, having rules that cover all > scenarios and are still mutually exclusive isnt a scalable solution.
