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.

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!
