Harvest costs - model

Allows you to control how the costs of harvests are simulated.

Cost Model

Indelningspaketet/FMPP: a less detailed time consumption function is used in the simulations. The function is the same as that used in the old FMPP software. The cost functions are described on page 83-65 in "Dokumentation av Indelningspaketet" (Report 528, 2003, Skogforsk). see Excerpt from the report (in Swedish only)
Skogforsk: Time consumption functions from Skogforsk (Brunberg 1995[2], 1997[3], 2014[4]). The implmentation of these models are described here: Media:Time_consumption_harvester_and_forwarder.pdf
If you provide a plugin cost function, it will also be listed here.
