Re: [rules-users] Drools Planner : multiple planning entities
I have choosen the SolutionInitializer way, and am trying to make it work. However I still have two questions that will need some help from you : 1 - A variable of a planning entity class can be itself a planning entity ? I take actually the cloudBalancing for example : It's possible to make of the cloudComputer class a planning entity class with a variable ( State which change the cpuPower instead of being constant ) ? this variable takes values via /ValueRangeFromPlanningEntityProperty/ from a list defined in the computerCloud. 2 - My second question is related to the first question example, the list defined as /ValueRangeFromPlanningEntityProperty/ has to be added in the facts of the solution ? if yes, how can I do that, given that each cloudComputer has his proper list. I hope that you see clearly what I need.

[rules-users] Guvnor Uploads without Eclipse
Hi I am currently looking at building a custom maven task that uploads BPMN definitions from a project to a remote Guvnor installation. I was looking at the current Eclipse Guvnor plugin and noticed lots of code around Eclipse (which makes sense :)) . I was wondering whether there was any generic code that I could take a look at without using eclipse dependencies? Any help would be appreciated.

Re: [rules-users] Using accumulate function-Performace Issues
Hi ,
I have used the modify function. It works, but its time
consuming.Since the fact gets modified at RHS ,the rule engine reprocess
the same.But the time taken for execution is more.
If any body have better idea please help.

Your posts use several terms others aren't familiar with. It's
difficult to imagine the data model behind this rule snippet, and
that's why you don't receive any answers.

Re: [rules-users] Using Decision Tables as Lookup Tables
Be advised that the approach you are intending has a dangerous blind spot you should guard against. What if Calculate Value doesn't provide a match for a company/region combination? You'll need an additional rule detecting the missing ones. A lookup table F( x, y ) can also be implemented by inserting facts of type F, and this can be done by a single rule firing with high priority, with a RHS containing all required inserts. -W 2012/4/10 Michael Anstis michael.ans...@gmail.com: Hmmm... the only way I can see this is possible (i.e. with the use of accumulate) is to use transient facts:- This can be set-up with a decision table quite easily (and ValuedRegion can be a declarative type that extends Region adding the value field) rule setup ValuedRegions - using a decision table when $Region( $score : score ) then insertLogical( new ValuedRegion( $score, [a value] ) ); end Your rule rule Calculate Value when $c : Company() $r : Region() $val : Double() from accumulate (ValuedRegion($score : score, $value : value ) , sum($score * $value)) then // Do Something end On 10 April 2012 14:51, Davout davout1...@gmail.com wrote: Hello, I'm trying to figure out how I can use a Decision Table as a lookup table.

Re: [rules-users] [Drools Planner] Proof-of-Concept Stock-planning System
Thank you for all the tips. In the mean time I was able to locate the source of serious performance killer. These 3 rules: http://nopaste.info/3f89c43eee_nl.html I tried to reorganize and re-optimize them at least 10 times to no avail. I'd appreciate, if anyone could suggest me how to change them to get the performance up. Until now I have tried: - reducing variable bindings (e.g. resource == $resource to resource == $maxLoad.resource) - moving accumulate from constraint rules to insert momentary load - joining sum for TUs and Picks in one accumulate - and number of other less useful changes still, if I add these rules the calculate count goes down from approx 5300 to 2000 per second which is more than a half.

Most of things (resource capacity, route within the stock system, etc.) are given and constant facts. Actually there is only one planning variable - time interval of a transport unit characterizing retention period within a given Resource. Like this: TU#1 is in Resource #A from 11:00 till 11:30- the optimal interval has to be planned Is the value range something like this: (A) - 10:00 till 10:30 - 10:30 till 11:00 - 11:00 till 11:30 - 11:30 till 12:00 Or like this? (B) - 11:00 till 11:15 - 11:01 till 11:16 - 11:02 till 11:17 - 11:03 till 11:18 ... From reading further, I presume (A). TU#1 is in Resource #B from 11:45 till 12:00- the optimal interval has to be planned TU#1 is in Resource #C from 12:30 till 13:00- the optimal interval has to be planned I have following problem size and constraints: - TUs per day: 160'000 - Amount of resources a TU travel through: 3 Do the TU need to go through it's 3 resources in a specific order? (C) No (D) Yes I presume it can not go through 2 resources at the same time. - Average smallest time interval: 15 Min - Planning period: 09:00 - 16:00 = 8 hours = 32 intervals - Initial planning window: 4-6 hours - continuous planning multiple batch execution time during the day after addition and/or retraction of number of TUs: 20 minutes (E) This is repeated planning (see documentation manual if you haven't already). So the problem size would be(?): (TUs * resources) ^ intervals = (160'000 * 3) ^ 32 = 6.305500958×10¹⁸¹ That's not a big search space. In some examples I 've seen 10^6800. Of course, the search space isn't the only metric to take into account (but I haven't found a good way to measure the other metrics, such as how-constrained-is-the-problem, how-big-is-the-snowball-effect, ...). I know there is no one answer to this question. I would like only to get your feeling on this problem. Would you take on solving this sort of problem with drools planner?

== $esId)
from $cxr.carrierTransmitEarthStationAssociations
then
insert(new EsLinkedUplinkCxr($es, $cxr)); //
end
--
2. Rule Carriers transmitted to transponders on same satellite
ruleflow-group businessRulesGroup
when
$cxr: Carrier()
then
System.out.println(Carriers transmitted fired);
end
-
the problem is if I add only carriers fact then second group execute, but if
I add earth station and Carriers fact second group doesn't execute. looks
like only one group executes
my test file is like below
-
kbuilder.add(ResourceFactory.newClassPathResource(mandatoryRules.drl),
ResourceType.DRL);

I am not able to figure out why both groups not are not being executed even
after I am inserting data to satisfy all of the rules.
I would be grateful, if someone could help me to get the clue.
