Revenues, costs and fuel consumption

The total cost of operating the fleet should be the sum of the six sub-parameters CREWCOST + FUELCOST + FIXEDCOST + CAPCOST + REPCOST + VARCOST listed below.



The parameter INCOME is the sum of all revenues of the company including landings, tourist trips, subsidies etc. This is not aggregated by species whereas the value parameter under landings only includes income from landings and is aggregated by species.
