Pagrindinių kirtimų sortimentinės struktūros ir pajamų prognozavimo galimybių tyrimai / Research on prognosis of assortment composition and income from final cut

Radzevičius, Sigitas 16 June 2006 (has links)
Amounts of pine sawlogs, pine pulpwood as well as spruce pulpwod can be estimated rather precisely. The accuracy of the prognosis is as high as 90%. The amount of spruce sawlogs can be prognosed with less accuracy (75%). The biggest errors are obtained by prognosis of smal dimensions softwood and hardwood as well as of birch pulpwood. Prognosis of birch pulpwood differs from actuall volume 3.7 times. When prognosed income is being compared with the actual one, very small discrepancies are found, though the assorment composition is different. The difference between actual and theoretical income were 2.4% and -0.5% respectively for 2004 and 2005.
