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
