A timber industry complex is a complex of technological processes linked with timber harvesting, wood transport and woodworking. For their optimization are used mathematical and economic methods. The brief overview of the application of mathematical modeling methods for the analysis and optimization of technological processes in the forestry sector is given in the article. Queuing theory is used for analysis of forestry process. For example harvesting technology with the round logs production for wooden construction is considered as G/G/1 queuing system. Well-developed models of queuing theory are recommended for analyzing of forestry process. Simulation models are recommended for deep analysis of forestry process.

The results of research of raw materials of the logs production for timber construction are considered in the article. Length of logs (for 6 meters assortment), diameter of logs (model logs) and shape of butt (an average shape factor of butt) were studied. The model log is a volume of cylinder which is equal to a calculated volume of logs. The theoretical laws of the random variable for these values are found. The Research was conducted at LLC "Biogran" in Petrozavodsk, Republic of Karelia.
