This article considers the issue of the efficiency of roundwood production, which depends on the formation of high-performance forest machine complexes. The authors substantiate the problem of searching for optimal logging complexes for specific natural and climatic conditions. In this paper, the authors analyze the definition of a technological parameter, its essence and types. Also, the article describes the technological process of a feller buncher. The results of the analysis of technological parameters of feller buncher under different natural conditions are presented. Dependences of the productivity of a feller-buncher machine on various natural and climatic factors have been revealed. The authors proposed the information-logic and mathematical models of the work of a feller-buncher machine. A detailed analysis of the components of the technological process of a feller buncher is carried out. Further, a formula is proposed for calculating the productivity of a feller buncher. The results of the work are presented in the form of dependency graphs. The graph of the dependence of the time of movement of the machine to the group of trees subject to cutting, from the relief of the terrain and the graph of the dependence of the time of capture and cutting of the tree on the diameter of the tree in the place of the cut are given.

Keywords: feller buncher, technological parameters, technological process, productivity, logging process, process modeling

An important direction for sustainable development of domestic production is a complex use of wood resources. In Russia there is a large amount of wood resources. Waste is generated at all stages of logging and woodworking processes. Researchers estimate in the Russian Federation annually produces about 35.5 million m3 of wood waste. Wastes produced by various physico-chemical, size, quality and other characteristics. Range of directions of development of waste from the activities of the forest industry is also great. Depending on the type of wood waste can be used in different directions of the domestic industry. The increasing use of waste wood resources is the most important link in the development of policy, resource conservation, environmental management, environmental safety. The study is supported by RFFI (grant No. 15-46-04294) and KGAU "KKFPNiNTD" (project: "Development of expert system on environmental protection and recycling of various wastes of production and consumption")

In article results of development of the mechanism of management of efficiency of use of wood resources at the timber industry enterprises are offered. It consists of five main stages, the implementation of which can decide whether the decision-making in certain areas of forestry development and individual businesses, as well as the development of strategic programs for their development. The proposed mechanism is tested on the example of Lesosibirsk’ timber industry in the region, allowing it to offer promising areas of development. Research is carried out with assistance of RGNF (grant No. 15-12-24003) and KGAU "KKFPNiNTD" ("Development of a control system of the forestry enterprise in modern conditions" project).
