114. Launching work orders into production of wood enterprise with the multi-criteria decision-making methodLeon Oblak, Boštjan Novak, Igor Lipušček, Jože Kropivšek, 2007, pregledni znanstveni članek Povzetek: Quality information is crucial for planning and running of production in wood industry companies. Information of crucial importance is the following: quality in the production process according to work orders and types of product, the information on the missing materials i.e. constituent parts according to projects i.e. work orders and the information on launching work orders into production. The method of multi-criteria decision-making was used for determining the order of launching group products into production. We studied three main criteria: market factors, organisation-production factors and economic factors. For computer support, we chose the computer programme DEXi, which represents the framework of the expert system for multi-criteria decision-making.

115. Analiza pomembnosti informacij za planiranje in vodenje proizvodnje v lesnih podjetjihBoštjan Novak, Leon Oblak, 2006, izvirni znanstveni članek Povzetek: V lesni industriji ločimo tri tipe proizvodenj: kosovno, serijsko in masovno. V raziskavi smo ugotavljali, katere informacije so ključne za uspešno planiranje in vodenje posamezne vrste proizvodnje. Potrdili smo hipotezo, da ima vsaka od omenjenih vrst proizvodnje svoje specifičnosti in zato so tudi vrste informacij, ki so potrebne za odločanje v posameznih proizvodnjah, različno pomembne. Rezultati raziskave, opravljene v dvanajstih slovenskih lesnih podjetjih, prikazujejo, katere so tiste informacije, ki so pri odločitvi v zvezi s planiranjem in vodenjem proizvodnje najpomembnejše. Izsledke raziskave bi bilo smiselno upoštevati pri postavitvi informacijskih sistemov v lesnih podjetjih.

116. Annual cambial rhythm in Pinus halepensis and Pinus sylvestris as indicator for climate adaptationPeter Prislan, Jožica Gričar, Martin De Luis, Klemen Novak, Edurne Martinez Del Castillo, Uwe Schmitt, Gerald Koch, Jasna Štrus, Polona Mrak, Magda Tušek-Žnidarič, Katarina Čufar, 2016, izvirni znanstveni članek Povzetek: To understand better the adaptation strategies of intra-annual radial growth in Pinus halepensis and Pinus sylvestris to local environmental conditions, we examined the seasonal rhythm of cambial activity and cell differentiation at tissue and cellular levels. Two contrasting sites differing in temperature and amount of precipitation were selected for each species, one typical for their growth and the other represented border climatic conditions, where the two species coexisted. Mature P. halepensis trees from Mediterranean (Spain) and sub-Mediterranean (Slovenia) sites, and P. sylvestris from sub-Mediterranean (Slovenia) and temperate (Slovenia) sites were selected. Repeated sampling was performed throughout the year and samples were prepared for examination with light and transmission electron microscopes. We hypothesized that cambial rhythm in trees growing at the sub-Mediterranean site where the two species co-exist will be similar as at typical sites for their growth. Cambium in P. halepensis at the Mediterranean site was active throughout the year and was never truly dormant, whereas at the sub-Mediterranean site it appeared to be dormant during the winter months. In contrast, cambium in P. sylvestris was clearly dormant at both sub-Mediterranean and temperate sites, although the dormant period seemed to be significantly longer at the temperate site. Thus, the hypothesis was only partly confirmed. Different cambial and cell differentiation rhythms of the two species at the site where both species co-exist and typical sites for their growth indicate their high but different adaptation strategies in terms of adjustment of radial growth to environmental heterogeneity, crucial for long-term tree performance and survival.
