Is it possible to specify both weight as well as volume of vehicle as capacity ?
For each shipment/service, I can specify both weight and volume. This is to ensure that vehicle suggested is correct both from weight as well as volume perspective.
I see only one field “Capacity[]” in vehicle type section.
Sure. The capacities array is user-interpreted. The optimizer only checks that the values with the same index are not surpassed. So just define 2 indices.
