There is provided a remote server (5) that receives position information, information on a harvest amount, information on an applying amount of a fertilizer, and information on an instantaneous fuel consumption amount. The remote server (5) calculates a revenue/expenditure distribution map (55) by a total of the revenue and expenditure, using a distribution of the harvest amount in a working area as the revenue and a distribution of the instantaneous fuel consumption amount as the expenditure based on position information of a tractor (3) in one farm field, and using a distribution of the applying amount of the fertilizer and the instantaneous fuel consumption amount as the expenditure based on position information of a combine harvester (4). |
