First read up on the difference between "score weight" and "score
levels":<br>
<a class="moz-txt-link-freetext" href="http://docs.jboss.org/drools/release/5.5.0.Final/drools-planner-docs/html_single/index.html#d0e3333">http://docs.jboss.org/drools/release/5.5.0.Final/drools-planner-docs/html_single/index.html#d0e3333</a><br>
Does your business want to plan higher priority workitems always (=
score level) or are there exceptions (= score weight)?<br>
Ask them this: if you can assign 1000000 low priority tasks or only
1 high priority task, what would you rather do?<br>

makes no sense to me, especially since 1) there are no restrictions
on engineer and 2) because it's the cause<br>

i know i'm far from get even closer. In order to define the
planner according to priority I think I should compare it
with entire list isn't? I noticed that in some rules, and
entire list is pointed. <br>

<br>
"Plan according to priority" is vague, here's are some suggestions
on implementation:<br>
<br>
A)<br>
When<br>
there's unassigned workorder<br>
and there's an engineer capable of doing that workorder<br>
and the engineer has a workorder with a lower priority (use
"exists" here)<br>
then<br>
the engineer should be doing the other workorder<br>
-1 (with the cause being the unassigned workorder)<br>
<br>
B)<br>
When<br>
there's an unassigned workorder<br>
then<br>
-1 * priority * 1000 (with the cause being the unassigned
workorder)<br>
