Abstract
A variety of natural-production conditions, which is necessary to conduct logging activities largely complicates the choice of forest machines for each individual company in the industry having logging sites in its composition. Depending on many natural and production conditions such as: slope, bearing capacity of soils, ambient temperature, maximum investments, etc., and the wide range of forestry equipment on the market, engineering divisions of the company solving a problem about the purchase of new or replacement of lost its performance machines are more and more difficult to make the right choice. This work presents a methodology for forming the system of forest machines with the natural and production conditions in a convenient form, not requiring special expert knowledge from the field of mathematical modeling or other areas of science. According to the methodology the first step is selection of basic machine and performing the first major operation in felling trees, then switch to the auxiliary machines which are linked to the underlying performance, to reduce the number of in-process stock. Selection of basic and auxiliary machines is provided that candidates and excludes important indicators. If in the process of selecting the logging machine does not meet the screening criteria for excluding indicators then it does not participate in the selection. Significant index can be neglected in case of discrepancy of candidates to stated requirements. The performance of the model was tested on the example of harvesting sites of the enterprises of the Krasnoyarsk region in spring 2016. In the course of the experiment the system of forest machines, meeting the required selection criteria, was obtained.

Summary
Многообразие природно-производственных условий, в которых приходится вести лесозаготовительную деятельность во многом затрудняет выбор лесозаготовительных машин для каждого отдельного предприятия отрасли имеющего в своем составе лесозаготовительные участки. В рамках данной работы представлена методика по формированию системы лесозаготовительных машин с учетом природных и производственных условий в удобной форме, не требующая от специалиста особых знаний из области математического моделирования или других областей науки. Выбор базовой и вспомогательных машин производится при условии соответствия кандидатов исключающим и значимым показателям. Если в процессе выбора лесозаготовительная машина не соответствует критериям отбора по исключающим показателям далее она не принимает участие в отборе. В ходе проведения эксперимента была получена система лесозаготовительных машин отвечающая требуемым критериям отбора. Ключевые слова: методика выбора системы лесозаготовительных машин, природно-производственные условия, базовая машина, вспомогательные машины. 1 – Lesosibirskiy Branch of the Reshetnev Siberian State Aerospace University, Lesosibirsk, Russian Federation
