There is currently no core developer activity on this, and it's not
planned near term. If anyone in the community wants to take this up,
would be great if they could build it into our web based dtable tool.

I have looked at drools-chance, and my understanding is that this module is
closely tied to PMML file format, I was more looking for a generic score
models (additive/weighted/...) that can be defined using excel (and at some
point through a custom UI).
I agree that this is not a core "engine" functionality, and can be built on
similar lines as the decision tables module. My original question was not
phrased properly :(
Now that we have covered the basics of my question, can either one of you
point to any work/discussion in the drools community in this direction?
Also, if I have some thoughts on this subject (creating this framework), who
would be the person(s) to brainstorm? Who would provide me with a go/no-go
for working on this?
