Hi Bernd,

is it possible to instruct xTour 1 not to generate the dima with roadbased routing but to calculate the dima with airlinedistance and airlinespeed? I think the good old eTour was able to do that?

Regards,
Volker

thats pretty easy: just don't provide a DIMA ID at the vehicle

BaseVehicle says:

dimaId Integer
The unique key to identify the distance matrix used with this vehicle (see DistanceMatrixCalculation). If the direct velocity is used, this parameter can be left empty.

You do actually have to set the directVelocity or else xTour will complain that you are not providing dima information. You can find the parameter on the PlanningParams . Common value we use is 64.

Hello Volker,

Taken from the planning params...

• Integer directVelocity : Assumed this speed ([km/h], > 0) for calculating the distances as the crow flies. If this parameter is set, the array of distance matrices will be ignored.
• Double directDistanceFactor : This factor is used if directVelocity is set (optional, >= 0). If set to 0.0, the default value from conf/TourOpt.ini is taken.

Bernd

Thanks alot!!!!
