[rules-users] Planner and optional rules

Hello.

I'm working on a planning system and my customer is requesting to use a rule
engine. Of course, we are gonna use Drools and we are considering planner.

The customer already talked about having hard and soft constraints, however,
one request of the users is to enable them to inactivate specific
constraints for some specific one-shot calculation when required.

I've been thinking of using specific RuleFlows in order to not use the
different constraints selected by the user, but is seems a bit long and
risky as the number of selectable constraints could be high therefore
increasing the number of combination (RuleFlows) to write.

Is there any native solution to this issue knowing that performances are in
the spotlight as well?

Thanx in advance.

Nico
