Cleaning Cost Per Ha / Hour
Depending on choice above, the options Cleaning Cost Per Ha or Cleaning Cost Per Hour will be displayed.

Biofuel Thinning
For biofuel thinning, specific cost functions and settings are used (Figure 2).
Forest Fuel Harv Cost Function
For harvesters, several functions are pre-set (1), but you can also add new functions. Click on the right of Forest Fuel Thinning Cost Function and select “Configure Coefficients…” (Figure 3) to open the form (Figure 4).
HarvesterCostThinFF
Hourly cost (per G15-hour) for harvesters.
ForwarderCostThinFF
Hourly cost (per G15-hour) for forwarders.
Forest Fuel Thin. Corridor Width
Corridor width at multi-tree handling (1 or 2 m).
G15 Prod. Corr. Forest Fuel Harv
Conversion factor for productivity in G0-time (which the functions are based on in this case) to G15-time for harvesters.
G15 Prod. Corr. Forest Fuel Forw
Conversion factor for productivity in G0-time (which the functions are based on in this case) to G15-time for forwarders.
Forest Fuel Forw Cost Func
Cost function (coefficients) for forwarding.
