Dear All, I'm trying to model multiple time windows of the same vendor by multiplying the vendors with different time windows and demand. This seems to work. However, I can do the same with the depot but it doesn't represent what I need. I'm using salomon tw example, but i need certain demand to be there in one time window of the depot, and other demand at the other time window of the depot. In other words, I would need to link demand at a time window of a vendor to a specific time window of the depot. Does anyone know if there is any possibility to do this? Or can somebody suggest me some further steps. I would be really thankful. Thank you all in advance, Kind Regards, Alain -- View this message in context: http://drools.46999.n3.nabble.com/Optaplanner-Linking-time-windows-of-ven...
