When flights get assigned at my newly built airport, vehicles such as airside buses and service cars often get scheduled in a order that I consider to be wrong. Very often these vehicles for remote stands have vehicles for flights that will not be leaving for multiple hours being prioritised over flights with under an hour until scheduled pushback. This often leads to kind delays for flights on remote stands as they are unable to get passengers or ramp agents to the stand.
The only solution to this problem that I have found is to have separate remote bus stops and service car stops for each remote stand, though this takes up a lot of room.
