Normiranje gozdnih del pri izvedbi drugega redčenja v spremenjenih gorskih gozdovih na Pohorju : diplomsko delo - visokošolski strokovni študij - 1. stopnja = Normalisation of forestry operations based on the performance of second thinning in secondery forests in Pohorje : B. Sc. Thesis - professional study programmesVrabič, LukaPri izračunavanju stroškov gojitvenih del v mladem gozdu pogosto ne razpolagamo s podatki, ki so zbrani v postopku odkazila. V tem primeru je smiselna uporaba sistema normiranja, kjer namesto drevesa ... kot enote mere za ugotavljanje učinkov nastopa površina. Raziskava obravnava primernost gostote izbrancev in gostote konkurentov kot kazalcev potrebne količine dela v primerjavi s prsnim premerom, kot uveljavljenim kazalcem pri enoti mere drevo. Za ta namen je bila opravljena časovna študija izvedbe redčenja v smrekovem drogovnjaku s primesjo jelke in bukve, kjer je bilo skupno posnetih 72 popolnih ciklusov sečnje in izdelave, od tega 57 na iglavcih in 15 na listavcih. Zastavljeni sistemi normiranja temeljijo na modelu funkcijske odvisnosti, kjer poznavanje neodvisne spremenljivke omogoča bolj ali manj zanesljivo napovedovanje odvisne spremenljivke. Uporaba linearne aproksimacije se je izkazala kot ustrezna metoda za napovedovanje predvidene porabe časa. Prsni premer se je izkazal kot najnatančnejši kazalec, medtem ko sta bila kazalca gostota izbrancev in gostota konkurentov po natančnosti enakovredna. Ugotovljena je struktura delovnega časa in težavnost dela po operacijah v produktivnem času. Na podlagi ugotovljenih učinkov je v povezavi z načinom nege opravljena kalkulacija stroškov ukrepa. Podana je ocena potencialnih izboljšav sistema normiranja, ki je ključnega pomena za racionalizacijo nege.Type of material - undergraduate thesis ; adult, seriousPublication and manufacture - Ljubljana : [L.
