The study is an analysis of the results obtained by the authors in the course of solving the problem of finding the best option for transporting wood from a harvesting point to a consumption point. The main indicators for determining the effectiveness of the supply chain, such as productivity, labor, cost, have been considered. The methods for determining the productivity of the used machines taking into account seasonality have been considered in detail: the influence of meteorological conditions, the change in the types and characteristics of the used transportation routes are considered. The methods for calculating the weighted average productivity of machines have been determined. Calculations of the performance when driving on different types of roads have been carried out based on the statistical data of the enterprises of the Krasnoyarsk Territory. The dynamics of these indicators is calculated depending on seasonality. The calculations of labor costs for the process of exporting timber in long-length stems and logs and analysis of their seasonal fluctuations have been made. The structure of the cost of the logging process by operations, as well as its change during the year, has been examined in detail. A comparative analysis of the magnitude and structure of costs for the resulting model of the optimal supply chain and traditional models used in domestic practice has been made. The values of unit costs per cubic meter of harvested timber are obtained for the calculated optimal logistic model and traditional options. A general comparison of timber transportation technologies used by domestic enterprises has been carried out. Logging sites located in the Krasnoyarsk Territory and providing wood with one of the largest enterprises in the forest industry have been used for numerical calculations.
