Hi, There are some rule attributes like: salience, agenda-group or activation-group etc. Read more about them on : http://labs.jboss.com/jbossrules/docs/index.html I think that you probably need salience attribute (integer value - default is 0) in order to controll your rules. rule "ruleName" salience 10 when conditions then actions end The rules with greater salience attribute value will be executed first. Even without salience attribute, the order of rules is not randomize. It depends on the order of facts assertion on working memory ( this will cause some rules activation).

If it is fired in random, there is any method or keywords to control the order of firing the rules? -- View this message in context: http://www.nabble.com/Order-of-firing-rules-tf3866064.html#a10952429 Sent from the drools - user mailing list archive at Nabble.com. _______________________________________________ rules-users mailing list rules-users(a)lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users --------------------------------- Choose the right car based on your needs.
