The disintegration of the integrated logging enterprises, as well as of the forestry enterprises and the reduced attention of the authorities to the production of specialized machinery and equipment, the logging production process, have led to a decline in the equipment of the logging enterprises with specialized machinery and the effective organization of their operation. Small, privately owned, poorly equipped with machinery logging companies have emerged. Practically we reverted to the technology of the 1960s. Foreign chainsaws are used for felling, delimbing and crosscutting. The skidding operation practically uses general-purpose tractors of МТЗ-80(82) type with the simplest technological equipment – a set of chokers. Some of the larger companies use foreign harvesters and forwarders. According to our research, forestry farms of the Republic of Bashkortostan are in a similar position. In order to increase the level of equipment and improve the organization of its work at the enterprises of the Republic of Bashkortostan we have considered and proposed for use a number of machinery sets. However, practice shows that it is not enough to acquire and equip the production with modern machinery and equipment. A production process must be set up to ensure the effective operation of these machines. Logging as a complex, multi-operated, discrete process can be carried out using a variety of technologies. The most common technology nowadays is the logging and hauling of assortments, for which various harvesting machines and equipment can be used. For the effective operation, harvesting machines performing individual operations are combined into machinery sets. However, current practice shows that it is not possible to match machines and equipment with the same or slightly different capacities. Therefore, the output of such sets is usually equal to, or even lower than, the output of the operation with the lowest capacity. In order to increase the output of the machinery set to the output of the leading machine (the machine with the highest capacity), it is necessary to calculate the modes of operation of machines for specific operating conditions. There are five sets of logging machines offered. The costs that the use of each of them will require are calculated. On the basis of the obtained data it is concluded that in the conditions of the Republic of Bashkortostan it is most economically feasible to use the following set: chainsaw for felling, choker tractor for skidding, two chainsaws for delimbing and crosscutting, lumber carrier for hauling.

This article discusses the possibility of reducing logistics costs for transportation using the genetic algorithm for solving the Traveling Salesman problem. As a solution, it is proposed to develop an algorithm of actions for optimizing cargo transportation routes and to work out some points of the algorithm that will bring the result to the desired form. Based on this, the steps that are included in this algorithm, which was developed using an application using the Electron framework (JavaScript programming language), are analyzed. Based on the proposed algorithm, a practical situation is resolved and an optimal route is drawn up for orders of the courier organization. Such an application will improve the technical and operational performance of the enterprise, strengthen coordination of work and shippers, reduce transportation costs, use road transport more efficiently.

Different variants of technological chain can be organized in logging process. Water or land types of transport can be used for transportation of timber. The use of timber landings where wood can be processed also increases the number of multiple variants of technological process. Performance of operations in various natural and production environment differs in productivity and material costs. Production efficiency depends on the choice of technology of logging operations in dynamic natural and production environment. The given research suggests the variant of the grapho-analytical model for solution of the set task. Detailed graphic models of transportation of wood from logging unit to consumer, loading /unloading and processing operations at the intermediate and lower timber landing are developed. They show possible options of technological chains of logging process. Mathematical dependences are shown on the basis of the problem of finding the maximum flow of minimum cost in the suggested dynamic network. They define the conditions for solution of the set problem.
