This article presents web-based information system, designed to assess the quality of forestry work performance. The web-based information system, called MojGozdar, represents and innovative approach to a more transparent service market. MojGozdar offers support in the search for forestry services. At the moment, the system incorporates over a thousand forestry contractors, offering diverse forestry services. The MojGozdar system covers a three-level sustainability assessment of the forestry contractors in a simple, clear, and objective way. On the first level, all involved forestry contractors get a formal suitability assessment following the traffic lights principle. The assessment made by a professional qualified assessor represents the second assessment level. The main principle of an independent professional assessment will be sustainable forest management and achievement of a higher standard in social, economic, and environmental aspects of work execution. Forestry contractors, who legally and formally meet the basic conditions, i.e. who were assessed as adequate at the first assessment level, can join the second level. The third sustainability assessment level is intended for the customers to present their experiences or opinions about the quality of the provided services. The comprehensive assessment system should increase motivation among the forestry contractors in competition and quality performance of works in forests. At the same time, this is a comprehensive system for the providers' quality objective assessment, also of the additional possibility for evaluating offers for work in the state-owned forests, where offered price is the only criterion at the moment.

The rationalization of working procedures during difficult market conditions is gaining increasing importance. For rational production, it is necessary to always be aware of what and how much to invest in the business process to obtain the desired products or services without economic loss. This article presents a tool for the assessment of costs in forest wood supply chains. WoodChainManager is a Web-based tool composed of three user modules intended for the assessment of material costs of individual machines or the total costs of all selected machines in a forest harvesting system. Users can test the impact of individual technologies on the total material costs of the harvesting system and thus optimize operation processes. The basic tool for describing harvesting systems is the matrix, which visualizes cutting and hauling from the standing tree in the stand to the forest products at the end user. The tool has built-in algorithms that prevent the selection of an illogical harvesting system. The selected method for calculating costs for individual machines is simple, but still reflects the state of the actually incurred costs. WoodChainManager offers cost calculations for a wide range of technologies, machines and appurtenant attachments. The authors of this paper wish to increase awareness and understanding of cost calculations and to offer the possibility to directly compare different harvesting systems.

Due to the rising prices of fossil fuels and promotion of renewable energy sources, we recently witnessed the growing demands of the public for the exploitation of renewable biomass potentials. Slovenian legislation very rigidly defines utilization of logging residues and the production of green chips. In practice, this allows uncontrolled actions that bring new technologies, which raises a number of issues particularly with regard to environmental and ecological burdens. This paper presents a methodological approach used at design of the decision-making tool for the selection of environmentally friendly harvesting system in the production of green woodchips by considering various ecological and technological factors. Basically, a threestep methodological process is used, where in the first step soil and terrain are defined, in the second step, harvesting systems taking into account the diversity in terms of economic impact and ecological suitability are proposed and, last but not least, harvesting systems are placed into decision matrix taking into account technological and environmental constraints of different harvesting systems. The article also suggests 13 harvesting systems that are arranged into decision-making matrix taking into account the ecological, technological aspects in the production of green woodchips.
