Fleet and trips
Vehicles, trips, and the fuel that was filled.
A vehicle has a state: out, in, or in the workshop.
A trip names the vehicle, the driver, and the place it went.
Fuel filled on the trip is a row. The month can be read without collecting slips.
A service due shows before the vehicle is sent on a long run.
The dispatcher sees which vehicles have not returned.
A breakdown is a note on the vehicle and the trip. The next assignment can see it.
Drivers see their own list. The office sees the yard.
The evening desk is trips closed, trips open, and fuel against those trips.
A new dispatcher can assign a vehicle from the board.
The desk follows the yard you already run: the key, the trip, and the return.
