2 DVRP solution using Optaplanner

[Sarbajit Das (Pick Assist)]

Hello Forum,

I would request some help with a project that we are working on. I need to solve a problem where one set of vehicles will need to be serviced by engineers at a specific points. 

Constraints are:
1) One vehicle needs to go to multiple points for servicing and that order of travel needs to be decided by the system (any service station station can be reached in any order) 
2) one vehicle will not move from the service station before finishing work at that point
3) there are less service engineers than service vehicles
4) There are no fixed start or end destination for the service engineers, while there are fixed start and end point for the service vehicles

I was thinking of this as a 2 - dynamic vehicle routing problem with time window constraints. 

Need suggestions as to how this problem can be modeled using optaplanner, if at all?? are there examples or instances of using a bilevel programming for such instances?

Thanks,
Sarbajit Das
