Later on, a GUI should be designed to allow a user to interact
with the model.
That's what Drools Guvnor is for.
Design your constraints in Guvnor, and solve your NP-hard problem with
Planner.
The integration in Planner for Guvnor needs to be improved and
documented though,
but people have already made it work by applying a small hack.

Andrei,
You should take a look at Drools Planner, which is designed to provide
a framework for solving NP-hard problems using local search. I don't
know how "user-friendly" you would consider it to be and there's no
GUI, but it sounds like it may be a good fit for you.

*Subject:* [rules-users] Using Drools to model and solve a production
scheduling problem with changeovers
Dear All,
I am looking for a user-friendly platform which would allow me to
model and solve a
*production scheduling problem with changeover times*. Since it's an
NP-Hard
problem, I am getting convinced that a CP formulation would be most
appropriate. Later on, a GUI should be designed to allow a user to
interact
with the model.
Is "drools" a proper platform for this? Are there any examples of this
type of problem solved with Drools?
I need to tackle a problem with 4 parallel machines, over 100 jobs and
100 changeovertypes (sequence dependant setup times between each job).
I would appreciate any help on this! Thanks
Kind Regards,
Andrei
