Thanks for the comprehensive response.
Just for the sake of comparison, can you tell me which products would be similar to OptaPlanner? I did some digging and only came across some Constraint Programming products, but they didn't look like they could handle the planning like OptaPlanner.
Best regards - Barry

For OptaPlanner (=Drools Planner) this is the correct mailing list :)Hi - Forgive me if this not the correct mailing list for my questions.
We 'll be moving to our own mailing list / webforum soon.
Yes, task assignment (~ workforce scheduling) is a common problem talked by OptaPlanner.
I'm looking for information about OptaPlanner, but first some background. I am using Activiti for BPMN workflows. Activiti uses RESTful services to retrieve tasks. I also use Alfresco to check a calendar against resources to prevent double tasking, etc.
So I am wondering if OptaPlanner can be used to create a schedule
That calendar resource(s) is probably part of the planning problem, because it sounds like your constraints need it.
See the quick start (docs) and the curriculum course example for inspiration.
That glue code you'll need to write yourself. Since it's all POJO based, that shouldn't be hard.and push it into Activiti.
OptaPlanner doesn't care where those POJO's come from and where they go to: XML (XStream, JAXB, ...), JPA (Hibernate, ...), ... it's all good.
If you want a lot of features in that integration glue code, camel might be a good idea. One day we might create optaplanner-camel to expose OptaPlanner as a REST/SOAP service (but that's pull based, not push IIRC).
Yes, that's a typical use case: Generate the planning with OptaPlanner but allow user's to change the result afterwards.I don't necessarily want complete automation as I'd like to be able to use a user interface to view what the scheduler came up with and allow users to change as needed 9even if there are scheduling errors).
In OptaPlanner you can even go further: You can make specific assignments "immovable" (see docs), so OptaPlanner doesn't move them if the user has locked an assignment.
Or even semi-immovable: OptaPlanner can move it, but at the expensive of a Score penalty (so only if there's enough gain in moving it).
Also look for "guiScoreDirector" in the docs.
Thanks for any assistance. - Barry
