<div dir="ltr"><div style="font-family:arial,sans-serif;font-size:13px">Beside the line "not Engineer(skill == $....." i managed to get close of that, but my system is way simpler, withing WorkOrder pojo, i have a skill and within Engineer pojo, also a skill field, both int field.

<div>I'm still not getting good with drools rules, i'm
trying several examples and basic ones. Some i did without any
problem and understood plenty well, but when I try to make an
approach to what i'm aiming, I'm not able to.</div>
<div><br>
</div>
<div>Right now I'm trying to compose this:</div>
<div><br>
</div>
<div>When</div>
<div> there's an workorder with skill</div>
<div> and there's and engineer with the skill and
capable of doing that workorder</div>
<div>then</div>
<div> the engineer should do it</div>
<div><br>
</div>
<div>So i tried something like this:</div>
<div><br>
</div>
<div>
<div>rule "assignSkillWOToSkilledEngineer"</div>
<div><span style="white-space:pre-wrap"> </span>when</div>
<div><span style="white-space:pre-wrap"> </span>$wo :

: Engineer(skill == $requiredSkill)</div>
</div>
</div>
</blockquote></div>
there's no restriction that the WorkerOrder is assigned to that
engineer, so it matches with every engineer of that skill?<div class="im"><br>
<blockquote type="cite">
<div dir="ltr">
<div>
<div><span style="white-space:pre-wrap"> </span>then</div>
<div><span style="white-space:pre-wrap"> </span>insertLogical(new

</div>
</blockquote></div>
the cause $engineer is a problem: If an engineer combines with 2
workorders, it will only count for 1 point due the way insertLogical
work.<br>
Normally the causes are the planning entities involved.<br>
Try <br><div class="im">
insertLogical(new
IntConstraintOccurrence("assignSkillWOToSkilledEngineer",
ConstraintType.NEGATIVE_HARD,
</div><div><span style="white-space:pre-wrap"> </span>1, <span style="white-space:pre-wrap"></span>$wo));</div>

I would write it like this (pseudo code):<br>
<br>
<div>
<div>rule "assignSkillWOToSkilledEngineer"</div>
<div><span style="white-space:pre-wrap"> </span>when</div>
<div><span style="white-space:pre-wrap"> </span>$wo :
WorkOrder( $requiredSkill : requiredSkill, $assignedEngineer :
assignedEngineer )</div>
<div><span style="white-space:pre-wrap"> </span>not
EngineerSkillRelation(skill == $requiredSkill, engineer ==
$assignedEngineer)<div class="im"><br>
then<br>
insertLogical(new
IntConstraintOccurrence("assignSkillWOToSkilledEngineer",
ConstraintType.NEGATIVE_HARD,<br></div>
1, $wo));<br>
</div>
</div>
end<br>
