Project job scheduling (a form of job scheduling) minimizes the total project delay when multiple projects share resources.

Love it! thanks!

Has this been compared with the MISTA entries to see how it would fare against the 9 who were finalists?

How can I solve the problem of
scheduling jobs on identical parallel machines using optaplanner?!

[@JC-rb1nc]

hi, has this progressed in the last 10 years? is it more efficient/faster? also, is there documentation so we can see how we can do the same exercise/test?

I know this is not the place to ask. When will the final release for 6.X.X be available?

[@cgfulton]

***** Thanks for the quick response. I have been developing my elastically scalable scheduling application since May. Everything is working great! I just needed to go through the process to satisfy product management.

This is the great solution, of this task, but i cannot find the documentation about how to create my own xml file. Maybe anyone can share some information?

[@cpcetic]

I advise trying the txt format which is more abstract and human readable

[@ivanalieskovska9350]

I would need that as well.

There is absolutely no explanation for the examples. There is just bunch of uncommented code which is totally useless. Would be fine if you could comment every line so people can actually understand what it does and why is it written the way it is. For example: what is job type (source / standard / sink)?

@@GeoffreyOptaPlanner Hi Geoffrey,
thank you for reply. Unfortunately this information is nowhere to be found. Not even in the challenge you've been referring to. This exact example is pretty complex and it makes me desperate when I can't find any information about it. I understand you can't comment every line, but at least the important ones would be nice. Cheers

the project job scheduling is optaplanner's worst example. We'd remove it if it wasn't that popular. It works and people do use it in production...
It will be replaced by a proper "job shop scheduling" example in optaplanner-quickstarts one day (not in 2021). First the "VRP simplification" work needs to land (probably end of this year), then it's time to make a simple, beautiful job shop scheduling quickstart.

@@GeoffreyDeSmet I hope the job shop scheduling quickstart could come as soon as possible, thanks.
