21.3 Cost Parameters
The cost parameters are used in the optimization calculation. Therefore define these
parameters before doing the calculation.
Open the menu and select [Cost Parameters] from the [General] menu to show the
[Cost Parameters] page. Set each item according to ship’s plan, etc.
At the [Cost] window, enter the cost/hour and cost/ton for heavy fuel oil and diesel oil.
At the [Fuel Consumption] window, define the fuel consumption figures for up to 12
different speeds. Before entering the data, plot the data on a graph, like the one shown
below. Use a second graph if, for example, diesel oil consumption is different from that
of heavy fuel oil. Reset the power to effect the settings.
