如何使规则引擎始终选择显着性较高的规则？

Question

我使用显着性来设置每个规则的优先级，但是当我使用fireAllRules时，它并不总是选择显着性较高的规则。如何使规则引擎始终选择显着性较高的规则？

触发规则的Actionlistener

simula.addActionListener(new ActionListener(){
            public void actionPerformed(ActionEvent e) {
                FactHandle fact1;
                fact1= new SimulaRegras(pleas, act, context.getText(), mtask, state.getText(),sal);

                ksession.insert(fact1);
                ksession.fireAllRules(1);

            }

        }
                );

Drools Main

public class DroolsTest {

        public static void main(String[] args) {
            KieContainer kc = KieServices.Factory.get().getKieClasspathContainer();
            new DroolsTest().init(kc);
        }

        public DroolsTest() {
        }

        public void init(final KieContainer kc) {
            KieSession ksession = kc.newKieSession("ksession-rule");

            TeleInterface t = new TeleInterface(ksession);
            FactHandle fact2;
            fact2 = ksession.insert(t);
        }
    }

规则结构

    rule "Num1"
            salience(sr.gSal(0))

        when 

            t: TeleInterface ()
            sr: SimulaRegras(pleasant == false && activation == false && context == "working", multitask == true, state == "stuck")

        then
            t.gMap.setEnabled(true);
            t.gMap.setForeground(Color.GREEN);
            t.background.setIcon(new ImageIcon("ponto.png"));
            t.action("gMap", false);
            t.infoBox("optimization", "add", "Adicionar ponto no grid map e fornecer o caminho");
            t.sSal(0);
end

我不太确定你想要实现什么，但使用显着性并不是可行的方法。基于事实属性中的值的显着性可以被逻辑所取代，即，通过检查不存在具有该属性值更高的该类型的其他事实。此外，修改提供显着性的属性不是一个好主意，因为Drools不会重新评估显着性。

我不打算进一步研究这一点，因为用户界面(TeleInterface)并不描述实际插入的内容。
