Re: [rules-users] Rules that cumulate on consequence

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 <lansyjp(a)gmail.com <mailto:lansyjp@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. Could you please advice on how this could be achieved. We run Drools 5.1.1 and Guvnor; rules are made using the guided editor with DSLs.
