The goal of the paper is to present the possibilities of simulating forest operation activities including cost flow prediction. The case study regarding wood flow and forest operation cost modelling was conducted in four municipalities located in western Slovenia (bordering to Italy). Input data of forest inventory and basic forest data were used in order to predict the wood flow in the test area. We modelled the available cutting volumes with the capacities of local sinks - notably sawmills. Unbalanced hinterland areas of specific sinks that do not cover the local sink capacities were changed (reduced or enlarged) on account of the adjacent hinterland areas with surplus or shortage of wood volume. The hauling distances and wood volumes for covering the sawmillsć capacities of the adopted (balanced) hinterland areas were studiedS pomočjo modela za logistiko in pridobivanje lesa smo povezali tehnološko verigo oskrbe z lesom od sečnje in izdelave, spravila ter prevoza lesa. Cilj prispevka je predstavitev možnosti predvidevanja (simulacije) aktivnosti v procesu pridobivanja lesa, vključno z vidika njihovih stroškov. Raziskava je bila narejena na primeru štirih občin v zahodni Sloveniji na meji z Italijo. Na izbranem območju je bil uporabljen gozdarski informacijski sistem, vključno z osnovnimi podatki popisa gozdov z namenom napovedovanja pridobivanja in transporta lesa. Modelno smo primerjali razpoložljive količine možnih sečenj s kapacitetami lokalnih porabnikov - predvsem žag. Na osnovi neuravnoteženih razmerij med kapacitetami porabnikov in zaledjem gozdov smo posameznim porabnikom spremenili zaledja (pomanjšali ali povečali) na račun sosednjih zaledij s pribitkom ali pomanjkanjem lesa. Na osnovi sprememb so bili analizirani stroški prevoza lesaTEXTznanstveno časopisjejournalsSlovenian National E-content AggregatorNational and University Library of SloveniaUniverza v Ljubljani, Biotehniška fakulteta
