The differentiated forest management focusing the integrated forest functions and keeping the principles of sustainability is based also on a rational (economically and environmentally appropriate) use of machinery - logging technology. For this purpose, we have developed a model for the selection of an optimal logging technology. The model is based on an evaluation of environmental, economic and ergonomic criteria for each technology. So far, it is possible to choose the optimal technology variant (machinery system) based on the evaluation of set of environmental and technological criteria (terrain accessibility, skidding distance, logging erosion, cutting method , soil bearing capacity, structure and parameters of trees, the location of loading points). The inclusion of other economic, ergonomic and energetic criteria is in preparation. Appropriate or optimal technology for each forest stand shall be selected from a wide range of commonly used technologies and devices used in Slovakia as well as advanced technologies and equipment described in the literature. Knowledge on environmental and technological evaluation criteria and parameters of technology and machinery from various sources (literature, own research results) are converted into formalized knowledge base using fuzzyfication and object approach. Created networks of dependencies are applied to the content of relevant information layers and databases, stored in GIS and database system. For their construction, we used NetWeaver software environment, directly linked to the EMDS system, which is a technological extension of the ArcGIS. The functionality of the proposed solutions was verified on large areas in belonging under management of the Krivan enterprise, an organization branch of the Slovak State Forests.
