Re: [rules-users] [Drools Planner] Multi depot CVRP / CVRPTW
Interesting. You mean that I could add another rule in the vrp example
that checks the vehicle TimeWindow of the customer against
CustomerVisitArrivalTime?
In that case is the CustomerVisitArrivalTime a planning variable and
in which domain class does it belong?
I'm still trying to wrap my head around the concepts. :-)

Hi,
I've been looking at the VRP example in Drools and I'm thinking about using
it for multi depot cvrp and / or capacitated vrp with time windows.
Has anyone else tried planner for these use cases and can maybe shed some
light on their implementation?
The VRP example is already capacitated.
Multi-depot is pretty easy: just assign different a different starting
Location for every Vehicle.
Unless you want Vehicles to change Depot sometimes, then it's a bit more
complex.
Time windows is more difficult if you don't want to break incremental score
calculation.
Doing an insertLogical() for the arrival time of every CustomerVisit should
work.
Then it's just a matter of checking if that logically inserted fact
CustomerVisitArrivalTime falls within the TimeWindow of the customer.

Mats
