The article discusses the optimization of transport costs and storage costs of wood biomass using mathematical modeling methods. The considered mathematical models allow to optimize transport costs by building the most efficient routes closed.

Keywords: transport timber, storage timber biomass, mathematical models, optimization

This paper presents mathematic model of optimization of expenses of stock-piling of timber and logging timber from felling areas to timber consumers by transport networks. This model optimize technological processes which appears during the process of stock-piling of timber and logging timber. 

Keywords: log truck, rail transportation in timber processing complex.

the analysis of foreign researches, which consist of processes of functioning timber lorries is given. Decrease transport expenses with minimization of empty run of timber lorries and formations of rational structure of this park has been proved.

Keywords: timber lorries, functioning

It article contains information about mathematical models which taking into account more factors affecting on the performance of logging trucks. Presenting the methodical approach that allows engineers to make management decisions that control of forest real-time and determination: the optimal composition of logging trucks, their technical and economic indices, charts of wood hauling, the volume of construction, reconstruction and maintenance of logging roads, the costs for these purposes and etc.

Keywords: Automobile forest transport, logging truck, haul road, scheduling, performance of the logging truck.
