What does more specific means? You have a fleet of N vehicles, a list of M locations. You have to visit all in the shortest amount of time. Now add time windows for the locations, now add the constraint that out of these M locations you have pickups which need to be delivered (one location needs to be visited before the other on the same vehicle ride). Add another constraint - several drivers need to meet at the same time at one of the locations.
