Development of forest resources is currently associated with significant difficulties, primarily due to unsatisfactory infrastructure in greater part of the forest area. It is necessary to create an effective, mathematically based forest infrastructure so that the forest industry will be developing actively. This will create the prerequisites for effective continuous and sustainable use of the forest. At the same time, the transport and economic availability of wood resources will increase significantly. There are many options for organizing the logging process by forestry enterprises. In most cases, they are selected by management based on personal experience. This study is a continuation of the work of the author's team on the complex problem of algorithmization and optimization of logging operations, taking into account the analysis of various moving and processing operations of wood resources. In previous publications, the authors presented a graphic-analytical model for solving the task. This article presents a description of the algorithm developed on the basis of the presented mathematical and graphic-analytical models for finding an effective technological chain of transport, loading and unloading and processing operations of the logging process in dynamic natural production conditions. The developed algorithm can be considered as a methodological basis for logging infrastructure design, taking into account the dynamically changing environment.

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.
