<br> The usual way to model that in production rules is to have each of your scores calculated in distinct rules, and have a rule with a lower salience to check the total scoring and decide if it should fire or not.<br>
<br> Another way to model this is to have support for uncertainty reasoning. Davide Sottara, a PhD student from Italy, is working on uncertainty reasoning for Drools, but his research is not ready for productization yet.<br>

<div dir="ltr">Hi,<br><br>We are in the process of evaluating JBOSS Drools for our software and so far Drools found to be a perfect match for most of our requirements.<br><br>Recently our customer has requested for a very interesting and important requirement and its synopysis is given below<br>
<br>Rule<br> LHS <br> Condition 1 / Condition Group 1 (assoicated weightage is 20)<br> Condition 2 / Condition Group 2 (assoicated weightage is 50)<br> Condition 3 / Condition Group 3 (assoicated weightage is 30) <br>
<br> RHS<br> Rule Action / Output<br><br>While calling the Rule Engine, the Rule Engine client will say "Give me all the Rule Output for the Rules matching 50% of the LHS"<br><br> i.e. We need to know the percentage of LHS match in the RHS<br>
Using this percentage, we will call the Rule Action / Output <br>Sample:<br> <br>if Condition 2 / Condition Group 2 and Condition 1 / Condition Group 1 are satisfied, then we need to have 70% (50% + 20%) match in the RHS.<br>
<br>Thanks a lot for your help and time.<br>-- <br>Waleed Zedan<br>
